Aircraft Accident/Incident Report
Mansfield, Massachusetts 02048
Saturday, September 8, 2007 10:30 EDT
NTSB Narrative Summary Released at Completion of Accident
A review of a video recording of the accident showed the airplane wavering during climb out, in a nose-high attitude, and beginning a turn to the left. The airplane reached an approximate altitude of 100 feet before increasing the turn to approximately 60 degrees. The airplane then appears to pitch nose down to a sharp roll to the left and impacts the ground. The National Transportation Safety Board's Vehicle Recorder Division Audio Laboratory conducted a sound spectrum study on video recording, which revealed that the fixed pitch propeller was spinning at approximately 2,340 RPM. During examination of wreckage it was discovered that the flaps were deployed at 10 degrees, and the airplane was about 64 lbs over the gross weight limit. The pilot's miscalculation of the gross weight limit would have resulted in a higher stall speed.
NTSB Probable Cause Narrative
The pilot's improper use of wing flaps during takeoff, which resulted in reduced climb performance and a subsequent stall. Contributing to the accident was the exceedance of the airplane's maximum gross weight.
