Incident Overview
The accident occurred shortly after the pilot received clearance for takeoff. Approximately one minute and thirty-six seconds into the roll, the tower controller inquired about potential difficulties, to which the pilot responded that she might need to circle. Observers noted the aircraft was porpoising at an altitude of 80 to 100 feet above ground level while approximately 6,000 feet down a 9,000-foot runway.
Flight Dynamics and Impact
Witnesses reported that the aircraft never climbed higher than 300 feet above ground level and began drifting to the left. As it approached the end of the runway, the engine sounded as if it were at full throttle while continuing to porpoise. Near the accident site, a witness observed the engine surging before the aircraft pitched nose-up and banked left at approximately 45 degrees. This was followed by a nose-down pitch, impact with trees, and subsequent ground contact.
Investigation Findings
Examination of the engine and flight controls revealed no evidence of pre-impact failure or malfunction. Fuel testing confirmed the fuel met specifications. However, significant cargo loading errors were identified. The forward baggage compartment contained approximately 244 pounds of cargo, exceeding the 100-pound limit. Additional cargo weighing about 211 pounds was found scattered throughout the cabin and outside the aircraft.
Weight and Balance Analysis
At takeoff, the aircraft was approximately eight pounds under gross weight but was more than four inches forward of the forward center of gravity limit. The exact placement of all cargo could not be determined because the NTSB did not interview the pilot or receive her report form. For calculation purposes, unlocated cargo was assumed to be in the aft baggage compartment, though this likely understated the forward shift caused by cargo found in the cockpit and cabin.
Regulatory Context
The FAA reported that the pilot was carrying property for compensation or hire in violation of 14 CFR Part 119.5(g). The pilot had agreements to transport mail to and from the Bahamas for a yearly fee.
