Investigation Summary
Flight 1 was a multi-stop transcontinental service known as 'the New Yorker'. On the night of the accident, the aircraft departed Buffalo at 21:07 for the leg to Detroit. Ground witnesses near Lawrence Station observed the aircraft flying in a manner that suggested a controlled but unusual descent. The aircraft entered a spiral to the right, completing about four full circles. As the radius of these circles tightened, the aircraft lost altitude until it was in close proximity to the ground. At the end of the spiral, the aircraft made a sudden 'zoom' or steep climb, reaching an altitude of several hundred feet before losing airspeed and stalling. The resulting dive was nearly vertical, striking the ground in a nose-down attitude. The impact and subsequent fire destroyed the airframe, leaving little evidence for investigators to determine why the crew had initiated the spiral or why they were unable to maintain level flight after the recovery from the descent.
Final Conclusions
The Civil Aeronautics Board (CAB) released its final report (File No. 5669-41) approximately four months after the accident. The board concluded that the probable cause was 'Undetermined'. While the flight path was well-documented by witnesses, no mechanical failure or crew incapacitation could be proven to explain the spiral descent and final stall.
