(FAA), and the lack of standardized understandable terminology for pilots and controllers for minimum and emergency fuel states. The flight left Medellín with more than enough fuel for the journey and progressed toward JFK normally. While en route, the flight was placed in three holding patterns. Due to poor communication between the air crew and the air traffic controllers, as well as an inadequate management of the fuel load by the pilots, the flight became critically low on fuel. This dire situation was not recognized as an emergency by the controllers because of the failure of the pilots to use the word "emergency". The flight attempted to make a landing at JFK, but bad weather, coupled with poor communication and inadequate management of the aircraft, forced it to abort and attempt a

. The flight ran out of fuel before it was able to make a second landing attempt. The airplane crashed about from JFK. Hundreds of emergency personnel responded to the crash site and helped save victims. Many of those who survived were severely injured and required months or years to physically recover. NTSB investigators looked at various factors that contributed to the crash. The failures of the flight crew were cited as the probable cause of the crash, but the weather, air traffic controller performances, and FAA traffic management were also cited as contributing to the events that led to the accident. This conclusion was controversial, with disagreement between investigators, passengers, and

Background

The aircraft involved was a Boeing 707-321B, registration HK-2016. The aircraft was manufactured in June 1967, and was purchased by Avianca from
Pan Am Pan American World Airways, originally founded as Pan American Airways and more commonly known as Pan Am, was an airline that was the principal and largest international air carrier and unofficial overseas flag carrier of the United States for ...
in 1977. By the time of the crash, the aircraft was 22 years old and had over 61,000 flight hours. The 707 was equipped with four Pratt & Whitney JT3D-3B engines modified with a
hush kit A hush kit is an aerodynamic device used to help reduce the noise produced by older aircraft jet engines. These devices are typically installed on older turbojet and low-bypass turbofan engines, as they are much louder than later high-bypass ...
to reduce noise pollution. Avianca personnel reported that they factored in a 5% fuel overburn into the performance calculations due to the hush kit, along with an additional 5% overburn due to the age of the aircraft. Additionally, maintenance crews had noted recurring issues with the aircraft's autopilot, including the altitude hold function. These same issues were reported on the aircraft's penultimate flight, but maintenance was unable to fix the autopilot, and it was disabled as a result. The flight was staffed by a crew of nine, including six

Co-pilot Klotz had been employed with Avianca for three years and had 1,837 hours of flight time, with 408 hours at night. Klotz had transitioned to the 707 the previous October and had logged 64 flight hours in the airframe, including 13 at night. Flight engineer Moyano had been employed with Avianca for over 23 years and had over 10,000 hours of flight time, including over 3,000 hours in the 707 and over 1,000 hours of night flying in the same airframe (and 2,986 hours of night flying regardless of airframe). All three flight crew members had previous experience in landing at JFK.

Flight 052 entered the CAMRN holding pattern at , having been cleared to descend prior to arrival at the intersection, and the flight descended further to while in the CAMRN holding pattern. At 20:44:09, while still holding at CAMRN, the New York Air Route Traffic Control Center (ZNY) advised Flight 052 that there was an "indefinite hold" and to continue holding at CAMRN. At 20:44:43, the ZNY controller told the flight to "expect further clearance" at 21:05. The flight had previously been given two delay estimates that had passed. At that point, First Officer Klotz radioed the controller, saying, "ah well I think we need priority we're passing nintelligible. The controller inquired as to how long the flight could hold, as well as what their alternative airport was. Klotz replied at 20:46:03 that they could hold for five more minutes. The controller once again inquired as to their alternative airport and Klotz replied at 20:46:24, "It was Boston, but we can't do it now we, we, don't, we run out of fuel now." A handoff controller listening in on the conversation called the New York Terminal Radar Approach Control (NY

) at 20:46:24 and advised the TRACON controller that Avianca Flight 052 could only hold for five more minutes. The handoff controller asked whether NY TRACON could take the flight or whether to send Avianca to its alternative airport. The NY TRACON controller replied, "Slow him to one eight zero knots and I'll take him." The handoff controller later testified that he had not heard Flight 052 say that they could no longer reach their alternative airport. At 20:46:47, the NY ARTCC radar controller cleared the flight to proceed to JFK at and to slow to . Flight 052 departed the CAMRN holding pattern at 20:47.


Landing attempt

At 20:47:27, the NY TRACON feeder controller told the flight crew to "expect an ILS two two left" "altimeter two niner six niner proceed direct Deer Park". At 20:54:40, the feeder controller directed Flight 052 to make a 360° turn. At 20:56:16, the controller gave the flight a

procedures. At 21:09:29, flight engineer Moyano stated that the controllers "already know that we are in bad condition". The captain said, "No they are descending us", and the second officer added, "They are giving us priority". At 21:11:07, the NY TRACON final vector controller informed the flight that they were 15 miles from the outer marker and instructed them to maintain an altitude of "until established on the localizer". The flight crew began preparing for an instrument landing approach, extending flaps and discussing the appropriate airspeed. The final controller instructed the flight crew to contact the JFK tower controllers and signed off. Klotz acknowledged the transmission. At 21:15:19, Klotz contacted the tower controllers and informed that Flight 052 was "established two two left". One minute later, the captain asked if he should lower the landing gear, but the first officer replied, "No I think it's too early now." At 21:17:30, JFK tower asked Flight 052 to increase their airspeed by 10 knots to . At 21:18:11, the flight was from the outer marker. Twenty-one seconds later, the first officer remarked "glideslope alive". At 21:19:09, the captain requested the landing gear be deployed. Almost a minute later, the JFK tower cleared the flight to land on runway 22L. The captain asked the first officer to confirm that the flight was cleared to land. At 21:20:28, the first officer began informing the captain that the aircraft was below the glideslope. At 21:22:07, Flight 052 descended to . The aircraft began descending beyond the angle of the glideslope, then began climbing above it, followed by a steeper descent. At 21:22:57, the first officer commented, "This is the wind shear." The first officer warned the captain about the sink rate and noted an altitude of at 21:23:10. As he warned the captain, the

The GPWS began four "glideslope" audible warnings a few seconds later, alerting the flight crew that the aircraft was below the glideslope. In response to the captain's inquiries, the first officer replied that he did not see the runway. At 21:23:23, the flight began climbing again, having come within of crashing 2 miles short of the runway. The landing gear was raised, and the first officer announced that the flight was executing a

Crash

The JFK tower controller asked the flight to climb to and make a left turn. At 21:24:06, the captain asked the first officer to "tell them we are in nemergency". The first officer told the JFK tower controller that "we'll try once again we're running out of fuel", to which the controller replied, "okay". A few seconds later, the captain again told the first officer to "advise him we are n anemergency" and asked if he did so. The first officer replied, "Yes sir, I already advised him." The JFK controller directed the flight to contact the NY TRACON approach controller once more at 21:24:39. The TRACON controller asked the flight to climb once more to . The captain asked the first officer again to "advise him we don't have fuel". The first officer replied, "Climb and maintain three thousand and ah we're running out of fuel sir." The captain once again asked whether the first officer had advised the controller of their emergency, and the first officer replied, "Yes sir. I already advise him hundred and eighty on the heading we are going to maintain 3000 feet and he's going to get us back." A minute later, the controller instructed the flight to turn to the northeast and asked the flight crew if they had enough fuel to be directed from the airport. First Officer Klotz replied, "I guess so thank you very much." At 21:29:11, Klotz asked the controller if he "can give us

now...?" The controller said, "affirmative sir turn left heading zero four zero". At 21:30:12, the controller cleared another aircraft for landing. Klotz briefly thought the clearance was directed at Avianca and began to tell Captain Caviedes to change course before the controller corrected him. The controller then asked Avianca to climb to . Klotz replied, "negative sir we just running out of fuel we okay three thousand now okay". The controller continued to direct the flight northward, away from the airport. At 21:31:01, the controller said, "Okay and you're number two for the approach I just have to give you enough room so you make it without ah having to come out again." At 21:32:38, the

The captain acknowledged. At 21:32:49, Klotz radioed the controller, informing him that the flight had "just ah lost two engines and ... we need priority please". The controller instructed the flight to fly southwest to intercept the localizer. Klotz acknowledged this. The flight crew selected the ILS. At 21:33:04, the controller informed the flight that they were from the outer marker and cleared them for an ILS approach on runway 22L. Klotz acknowledged. That was the final radio transmission from Flight 052. Caviedes asked if the ILS had been selected. Klotz replied, "It is ready on two" at 21:33:23. One second later, the CVR stopped recording. At 21:34:00, the controller tried to radio the flight, asking, "You have enough fuel to make it to the airport?" There was no response. The NTSB report estimates that around this time, the flight crashed. The aircraft descended without power, clipped several trees and posts, and crashed onto a hill with a 24° slope in Cove Neck, New York. The fuselage partially fragmented into three distinct pieces. The cockpit and forward cabin separated from the rest of the airframe and were hurled over the crest of the hill, coming to a stop from the rest of the wreckage. The rest of the fuselage stopped within after impact. The main fuselage came to rest on the upslope of the hill, facing south, with the forward end extending over the crest of the hill. The right side of the forward end of the fuselage fractured a residential wooden deck.


Recovery


First response

Residents of Cove Neck immediately called emergency services. Jeff Race, a paramedic and member of New York City's Emergency Medical Service, who lived half a mile from the crash site, was the first rescuer on site. He reported that most passengers were still strapped in their seats and the survivors were crying out for help. Survivors later commented that it took about half an hour for rescue teams to arrive. Initial reports to emergency services reported that a much larger

had crashed. Fire Chief Thomas Reardon of Oyster Bay Fire Company No. 1 was in charge of the initial effort to remove people from the wreckage. In his first call to the Nassau County Fire Commission dispatch, he requested all the help available. Thirty-seven fire and ambulance companies, as well as more than 700 Nassau County police officers arrived to help. Other companies that were not called showed up voluntarily to assist. The swell of support created major problems for extricating survivors. The crash was only accessible to vehicles via a single residential street. With the surge of rescue personnel who converged on the area, the roads leading to the site soon became choked with traffic. Emergency vehicle drivers abandoned their vehicles contrary to established policy in the course of the rescue efforts. This prevented other vehicles from being able to access the crash area. The road was so impassable, many rescue workers left their vehicles miles away and made it to the scene on foot. Fog also grounded rescue helicopters for two hours. As a result, many critically injured survivors were not evacuated until 23:30. Eventually, four helicopters from the New York City Police Aviation Unit evacuated 21 people from the crash site. Also, major problems occurred with communication by rescuers. Radio frequencies became overloaded, and authorities on site were unable to make command decisions in some cases. The head of surgery of the Nassau County Medical Center was present at the scene, but unable to direct patients to the best locations because many rescuers were radioing the center itself to get advice on where they should send the survivors. Medical professionals on site reported that some hospitals received the most up-to-date information by watching the news coverage. Three of the passengers found alive died of their injuries.

Firefighters and medics erected ladders next to the airframe wreckage and led passengers down on stretchers and to the triage sites. At these sites, doctors tagged the critically injured patients for immediate evacuation. At least 30 bodies were gathered on the makeshift morgue at the McEnroe property by 03:00 the following morning. Passenger Astrid Lopez was initially believed to be dead due to her severe injuries, and officials placed her body in the morgue. A rescuer soon heard her moans, and she was sent to a hospital. Some medical responders were turned away from the scene by police to help ease the congestion. By 03:30, all the survivors had been evacuated to hospitals. At least one emergency responder was hospitalized as a result of the rescue efforts. Many local New York residents showed up at hospitals with food or blankets, or to volunteer as Spanish interpreters. The

Casualties

Of the 158 people on board, 73 died as a result of the crash. The lead flight attendant was the only crew member to survive, while the remaining flight attendants and all three flight crew members died. Of the surviving passengers, 72 adults and children over three years old sustained serious injuries, while two sustained minor injuries. Of the 11 infants, two sustained minor injuries, eight were seriously injured, and one died. The surviving flight attendant testified that no communication was made from the cockpit as to the unfolding situation, thus no warning came in the end to assume

s. The NTSB investigators found severe damage on the floor of the cabin, leading many of the passengers' seats to fracture where their legs met the floor track. This fracturing permitted many of the seats to come loose during the impact and aggravated the passengers' injuries. The report posits that the passengers' legs hit the lower seat frames in front of them. At the same time, the seats collapsed and twisted downward and to the left, likely causing hip and spinal fractures. As the impact progressed, the seats, now separated, flung passengers forward into each other and into other wreckage, causing head injuries and lacerations. Passengers holding onto infants reported being unable to either prevent their children from being ejected from their grasp in the impact or locate their children in the darkness afterward. The NTSB held that, had the children been in FAA-approved child seats, many injuries might have been mitigated. Rescuers remarked that one rescued baby was found smiling. The NTSB was unable to accurately chart where individual passengers were seated because Avianca only assigned seats to a few passengers, and many who were assigned reported moving after takeoff. The cockpit was severely damaged in the impact. It struck an oak tree, which penetrated the area occupied by Klotz and Moyano. All the seats occupied by the flight crew were found outside the cockpit. Neither of the pilots' seats had shoulder straps as were required by United States domestic passenger flights. At least one flight crew member was airlifted to Nassau County Medical Center. The NTSB report states that all of the flight crew "died from blunt-force head and upper torso trauma." Five flight attendants also died from blunt-force trauma to the limbs, abdomen, chest, and head.


Investigation

The NTSB commenced an investigation, which began shortly after the crash, and concluded with the issuance of its final report on April 30, 1991. Because it involved a Colombian airline, Colombia's Departamento Administrativo de Aeronáutica Civil (DAAC) also conducted an investigation into the accident. A survey of the wreckage revealed that the tail was mostly intact, and all control surfaces were connected to the pilots' controls. Both wings had been severely damaged on impact and fractured into several pieces. The flaps and

No evidence was found of any control surface failure prior to the crash. Investigators realized that none of the four engines had been under power at the time of impact.

. The FDR was an older oscillographic foil model. In 1989, the FAA began requiring domestic carriers to change to digital FDRs to minimize the errors that foil models produced. This requirement did not apply to international carriers. The Avianca FDR foil was found to have been taped down at some point prior to the flight, and thus was inoperative. The NTSB recommended in the Avianca report that the FAA take an "active role in ensuring upgraded international standards" for flight recorders. The CVR and ATC recordings became vital sources of evidence for the crash. The investigators also looked at meteorological factors that led to flight problems. The NTSB investigators found that the weather data which the flight crew received in Medellín were 9–10 hours old. Additionally, the alternate airport on the flight plan,

in Boston, was forecast to be below the minimum for safe landing. The NTSB also stated that the flight crew should have been more aware of these problems and cited these deficiencies as evidence of inadequacies in the dispatch of the airplane. The NTSB also found no evidence that the flight crew ever requested weather information en route or communicated with Avianca dispatchers about their fuel status and intents as other flights did. Flight 052 did not make contact with FAA

s or flight watch en route, and the NTSB was unable to determine why. The flight did not express any concern to ATC about their fuel situation during the first two holding patterns that the flight made. The first indication of worry came at 20:09 when the flight crew inquired about delays at Boston. The NTSB posited that the flight crew might have become confused about the "expect further clearance" (EFC) times they were given. This confusion may have been the reason that the flight continued to hold, burning up its reserve fuel to the point where it could no longer divert to Boston. Investigators also cited the flight engineer for failing to calculate the "minimum approach/landing fuel quantity." The report references the 360° turn that the flight was ordered to make at 20:54 as evidence that the crew should have known that they were being treated routinely and ''not'' given any emergency priority. Instead, the CVR revealed that the flight crew was convinced that they were being given priority. Additionally, the NTSB criticized the first officer for failing to use the word "emergency" as the captain had insisted he do. Compounded with the apparent inability of the captain to hear or understand the radio communications, the NTSB called the situation a "total breakdown in communications by the flight crew." Summarizing, the investigators cited "the flight crew's failure to notify ATC of their fuel situation while holding at CAMRN in order to ensure arrival at the approach fix with an adequate approach minimum fuel level and a breakdown in communications between the flight crew and ATC, and among the flight crewmembers" as the two main factors that led to the crash. Investigators asserted that the performances by the traffic controllers were proper and that the misunderstandings that were made were reasonable. None of the controllers involved considered the word "priority" or the assertions by the flight crew that they were running out of fuel to be indicative of an emergency. The report provided various examples of the flight crew failing to convey the danger of their situation, even moments before the engines flamed out. Although the investigators felt that the communications from the ATC personnel were "proper," the NTSB voiced concern over the controllers ''not'' placing significance on the word "priority." At a public hearing, it was revealed by an unrelated pilot that the emphasis on the word "priority" by the Avianca crew might have come from training and bulletins from Boeing that used the word in relation to fuel emergencies. Avianca also used the word "priority" in its publications on low-fuel status procedures. ATC controllers testified that "

", and "emergency" were the three phrases that they would respond to immediately. The report also stated that "priority" was defined in the ATC Handbook as "precedence, established by order of urgency or importance." As a result of this linguistic confusion, the NTSB recommended that the FAA work with the

to develop a standard glossary of clearly defined terms, as well as notify foreign carriers that they must be knowledgeable of ATC rules and procedures. The NTSB also cited the captain's inability to land on his first attempt as contributing to the crash. The investigation revealed that wind shear was a significant factor in the failed approach, but that other factors probably contributed. The report cited recurring maintenance problems with the airplane's

as a possible factor. Since the pilots had been forced to fly manually from Medellín, investigators believed this might have added to exhaustion and stress in the cockpit. For evidence, the NTSB pointed to nine instances where the captain asked the copilot to repeat the ATC instructions or to confirm the aircraft configuration. This stress, investigators asserted, would have degraded the flight crew's performance on final approach. Investigators also looked at the traffic management by the Central Flow Control Facility (CFCF). The CFCF, in communication with NY TRACON, established an airport acceptance rate of 28 aircraft landings per hour that morning. Later, a CFCF supervisor contacted NY TRACON and requested a higher rate of 33 landings per hour. This acceptance rate, investigators concluded, was based on inaccurate weather conditions. The report concluded that these traffic-management problems contributed to the conditions that led to the accident but did not lead directly to the accident.


Controversy

The probable cause of the crash was determined by the NTSB to be "the failure of the flight crew to adequately manage the airplane's fuel load, and their failure to communicate an emergency fuel situation to air traffic control before fuel exhaustion occurred." However, two NTSB members filed dissenting opinions in the report. Jim Burnett voted against the adoption of the report because he felt it did not adequately address the failures of the air traffic controllers or the FAA's role in allowing more traffic than JFK could handle. Christopher Hart filed a partial dissent because he disagreed with the report's findings of a lack of standardized terminology. In his dissent, he wrote that "we do have standardized understandable terminology ... that would have adequately communicated the existence of a dangerous situation, and the problem was that the pilots failed to use this terminology with the controllers". Colombia's DAAC investigators also disagreed with some of the NTSB's findings. In a comment on a draft of the NTSB's report, the DAAC recommended that the NTSB place some responsibility on the controllers for their "inadequate handling" of the Avianca flight. The DAAC also recommended that the NTSB encourage modifying the EFC system, and that FAA regulations should require an "active flight-following system" to assist flight crews in evaluating weather and traffic delays.

after a nurse informed police that 46-year-old Antonio Zuluaga had swallowed containers filled with cocaine. Zuluaga, who had a fractured spine, broken ribs, and a dislocated hip, was the second passenger to be found in possession of cocaine packages, after doctors operating on Jose Figueroa on the day after the crash to stop internal bleeding had also discovered packets of cocaine. Zuluaga and Figueroa pleaded guilty to second-degree criminal possession of a controlled substance. Figueroa was sentenced to seven years to life in prison, and Zuluaga was sentenced to six years to life. Many crash survivors suffered long recoveries from the physical and psychological traumas they endured. A month after the crash, an orderly caravan of around 1,000 vehicles drove to JFK while some demonstrators laid wreaths in the international terminal lobby to protest the handling of the flight. Some survivors sued the FAA, accusing the agency of failing to ensure the flight's safety. In July 1990, Avianca offered $75,000 to each crash survivor or the relatives of those killed. The U.S. government eventually joined Avianca and reached a settlement estimated at over $200 million in damages to the victims. The same summer, Avianca flights declared two notable fuel emergencies. The first happened in June, when a flight declared a "minimum fuel situation" and landed with only 10 minutes' worth of fuel left. The second happened in August, when Avianca Flight 020 declared it had "only 15 minutes of fuel left". Confusion arose as to what the pilot meant, but controllers declared an emergency pre-emptively and cleared the plane to land immediately. The flight was later found to have had over two hours' worth of fuel remaining. As of 2025, Avianca has not retired the flight number. Avianca Flight 052 is now a flight from Lima to Bogotá. However, Avianca has changed the numbers for the now non-stop flights from El Dorado to JFK, designated as Avianca Flight AV210, AV244 and Flight AV020 respectively while the airline continues to operate the Medellin to JFK nonstop sector as AV042 and AV144.
