What happened
The aircraft was operating on a personal flight when it attempted to land at Fort Knox in Kentucky. During the final approach and landing phase, the pilot contacted the ground approximately 100 yards short of Runway 36. The impact resulted in substantial damage to the airframe, specifically affecting the nose section, the left main landing gear, both wings, and the propeller assembly.
The investigation
A subsequent examination of the wreckage and flight data revealed that the aircraft was not within its certified weight and balance envelope at the time of the accident. Specifically, the investigation determined that the N6666P had exceeded its center of gravity limits during the landing maneuver. This condition likely contributed to the inability to maintain proper pitch control or flare attitude necessary for a safe touchdown on the intended runway surface.
Findings
The primary factor identified in this incident was the exceeding of center of gravity limits. Operating an aircraft outside its approved CG range can severely degrade handling qualities, particularly during critical phases such as landing. The resulting damage confirms the severity of the impact caused by the off-runway touchdown.
