The accident and rescue operations
The 1977 Cessna 172N registered TF-ABB took off from ReykjavÃk Airport at 10:38 on the morning of 3 February 2022. The flight plan indicated a two-hour sightseeing flight. Footage from security cameras from summerhouses near Þingvallavatn showed the plane about an hour later doing what appeared to be an attempted landing or touch-and-go on the southern part of Þingvallavatn lake which was at the time covered in thin ice. The plane hit the ice and sank. No distress call came from the plane and the plane's emergency transmitter did not send any messages. 112, the emergency line, did however receive a few-second call at 11:51 which later turned out to be from the phone of one of the passengers. When the plane did not arrive back at ReykjavÃk Airport at the right time, the plane was reported missing. The search operation that followed was the biggest of a missing plane in Iceland in over 40 years or ever since TF-ROM went missing in May 1981. Over 1,000 members of the Icelandic Search and Rescue teams, along with anCause
In the preliminary report from the Safety Investigation Authority of Iceland ( Icelandic: ''Rannsóknarnefnd Samgönguslysa'') on the accident it was reported that the plane flew for around 7 seconds at a very low altitude over the water before it landed in it. In May 2024, the Safety Investigation Authority (SIA) published its findings and attributed the accident to an intentional or unintentional landing on the frozen lake with human factors considered a contributory factor. The pilot was known to have previously landed on icy waters where he previously inspected conditions. The SIA found no evidence that he had inspected the conditions at Þingvallavatn beforehand and thus could not conclude whether the landing was intentional or not. Regardless, as soon as the plane touched the ice, the surface collapsed and the plane landed in the water and sank within two minutes. The impact of crash was not enough to activate the emergency transmitter. Despite the fact that the occupants managed to escape the plane after impact, it was concluded that due to the weather conditions that they had no chance of reaching the lake shore.Aftermath
In the aftermath of the investigation, the Safety Investigation Authority directed the Icelandic Transport Authority to implement the installation of new ADS-B transmitters in all manned aircraft flying in Icelandic airspace. It furthermore directed the Icelandic Coast Guard to establish a response plan with Coordination Center of the Department of Civil Protection and Emergency Management regarding the organization, implementation and responsibility of a search for a missing aircraft.Victims
The pilot was Haraldur Diego, chairman of the Aircraft Owners and Pilots Association (AOPA) of Iceland and a known figure in airplane photography tours in Iceland. The three passengers were from a group of ten people that were present in Iceland to participate in an advertising campaign for the Belgian clothing line ''Suspicious Antwerp''. Among the passengers was skateboarder and YouTuber Josh Neuman, along with Nicola Bellavia and Tim Alings. On 12 April 2022, Haraldur's 50th birthday, a memorial service was held with candles being lit and floated on Þingvallavatn.References
