Even if the aircraft should be found, the chances of determining the reason for the accident are not good. Especially if it was either related to icing or lack of instrument flying skills in difficult conditions. Engine problems, which can be seen by analysing the wreckage, would probably have been communicated by the pilot who was in radio contact with ATC.
