A flight with seven passengers and a pilot crashed on Allen Hill after a missed approach. The pilot and two passengers were killed, while five others were injured.

Flight Details and Departure Information The aircraft departed Boston-Logan at 2028LT, carrying seven passengers and a pilot. The flight was originally scheduled to land in Rockland, but foggy conditions prevented the aircraft from landing at that destination. As a result, the flight was redirected to Augusta. The aircraft was cleared for a VOR approach at 2114LT. At 2127LT, the flight reported a missed approach and was subsequently cleared for another VOR approach. The last known transmission from the flight occurred at 2140LT, when the crew reported being four miles out. The wreckage was later located in a heavily wooded area on Allen Hill, at approximately the 520-foot level. Allen Hill is a prominent terrain feature that stands 640 feet high. It is situated approximately 4 nautical miles from the threshold of runway 17 and eight-tenths of a mile west of the approach radial. The accident resulted in the deaths of the pilot and two passengers. Two passengers sustained serious injuries, and three passengers received minor injuries.

Probable cause

The NTSB determines that the probable cause of this accident was the improper action of the pilot in discontinuing the execution of a non-precision instrument approach and attempting to maintain visual flight while operating in instrument flight conditions at an altitude below the level of obstructing terrain.
