When the Canadian company made test flights and during the aircraft's first several passenger flights for Partnair, the FDR recorded almost no abnormal vibrations. Gregersen, M.; Jensen, S. & Knudson, P.J. The metal in the bolts was not strong enough and failed when resonant vibration occurred in the auxiliary power unit.The FAA investigated false parts and captured illegal parts dealers in This entry is from Wikipedia, the leading user-contributed encyclopedia. The FAA found that there was an industry for making thousands of worn and inferior parts to look like newly manufactured parts. Investigators found the four bolts/pins that held the tail on to the fuselage. In the 2000s, Schiavo said that counterfeit parts are not proliferated as often because there is more regulation in that time period than in the 1980s and the 1990s.The crash was featured in Season 7 of the Canadian made, internationally distributed documentary series Improper maintenance, rudder malfunction due to substandard partsAir Ontario Flight 1363, Air France Flight 296, Atlantic Southeast Airlines Fl, Air France Flight 358, Ethiopian Airlines Flight 409 The unidentified objects found at a high altitude by Swedish radar were likely the shroud doors, which had separated from the aircraft tail.

The expert concluded that the needle supposed to have been recording the altitude had been shaking so much that it left another mark on the foil.
If the rudder moved in a violent manner, the weights would also move violently and hit the shroud doors. At 1640 hrs the air traffic controller tried to contact PAR 394, but there was no reply. They also discovered that one of the three mounts holding the APU was broken.The two shroud doors on the aircraft tail were not present in the recovered tail. A long and arduous journey of the investigation from the crash backward in time to find the root cause of the crash of Partnair flight 394 to be nothing more than human greed. The investigators concluded that the F-16 would have had to have been within a few metres of the Convair to have affected the passenger aircraft; the investigators had no evidence that the two aircraft were that close together, and the AIBN investigation found no connection to the accident. The airline owed so much money that, on the day of the accident flight, the Norwegian aviation authorities sent a notice to airports telling Norwegian airports to not let any Partnair aircraft take off since Partnair had not paid several charges and fees.The flight crew consisted of Captain Knut Tveiten and First Officer Finn Petter Berg. There were no identifying marks or maintenance records for the strut.
Witnesses of the crash said that they heard a loud noise as they saw the aircraft fall. Accident Investigation Board Norway (AIBN) investigated the disaster and were able to recover 50 of the 55 bodies before sending them through autopsies in Denmark. With Stephen Bogaert, Hardee T.

This told the investigators that the aircraft disintegrated in the air.
In the investigation, it was found that the crew triggered the fire extinguisher for the APU.Some initial speculation in Norwegian press stated that a bomb brought down Partnair.
