It was on July 8 last year that nine people died in a plane crash in Örebro when a plane crashed shortly after takeoff.
The Accident Investigation Board Norway has previously said that there is no indication that there were any serious technical faults on the aircraft.
The Accident Investigation Board chose to send two flight investigators over 600 km to be able to conduct reference flights for three days in Alaska in early May.
The accident plane is of the unusual model DHC-2 Turbo Beaver from 1966.
- There are only a few left.
But here we found one that was in a really excellent condition, says Peter Swaffer, head of department at the Swedish Accident Investigation Board.
Peter Swaffer states that the flights gave good results.
- This was a big last part in our fact collection.
We have a clear picture of everything, he says.
Rigged the cabin with cameras
After careful preparation, the flights were carried out at an altitude of several thousand meters.
When the plane crash occurred, nine people were on board.
The investigators tried to recreate the conditions that prevailed that day.
- We have no people on board.
However, we have loads, sandbags and so on, to simulate the corresponding load.
Then the entire cabin is rigged with recording equipment and gopro cameras, says Peter Swaffer.
Final report this autumn
The cost of the trip was approximately SEK 75,000.
The Accident Investigation Board used its own pilots, which according to Peter Swaffer was a great saving.
Before the summer, the Accident Investigation Board hopes to be able to inform relatives and others concerned about how the investigation went.
The goal is for the final report to be presented in September.
