The aircraft, Flight 946, had been cleared for an approach to the Lebanon Regional Airport, West Lebanon, New Hampshire, at 1808.

Probable Cause

The Board determines that the probable cause of this accident ws the premature initiation of a descent; towards the Minimum Descent Altitude, based on navigational instrument indications of an impending station passage in an area of course roughness. The crew was not able to determine accurately its position at this time because they had performed a nonstandard instrument approach and there were no supplemental navigational aids available for their use.
