Two parallel investigations were undertaken , one by HSL and one by Namdal Police District . The latter criticized the former because there were not given access to the cockpit voice recorder ( CVR ) . Since 1989 both the police and the prosecuting authority had not been represented in the accident investigations . HSL emphasized that they had no legal obligation to submit the tapes to the police , that the police had not asked for the tapes after Widerøe Flight 839 in 1990 and that the Ministry of Transport and Communications supported this line . The reason for the rules was that the Norwegian Airline Pilots Association did not want the records from the CVR to be used in criminal cases against pilots . The investigation board stated that they would forward any information which supported criminal violations , while Namdal Police District stated that it was necessary for an independent police investigation to identify any criminal violations . The Norwegian Data Inspectorate 's director Georg Apenes supported the police in their request for the tapes
