What happened
The pilot was operating an aircraft with the intent of transferring it from a friend's private airstrip to a recently constructed strip at his own property. Prior to attempting the landing, the pilot conducted a visual inspection of the runway surface. Based on this assessment, he determined that the ground conditions were sufficient for a safe landing.
The pilot executed a full flap landing, extending the flaps to 40 degrees to reduce approach speed and increase lift at low speeds. Upon touchdown, the aircraft rolled onto a section of the runway described as a soft area. The soft surface caused the wheels to sink slightly, resulting in rapid deceleration. The sudden loss of forward momentum caused the nose gear to collapse, leading the aircraft to nose over.
The investigation
Post-acc examination revealed that the primary factor contributing to the incident was the condition of the landing surface. The pilot's initial assessment of the runway as "good enough" proved incorrect due to the localized soft spots which were not apparent during the brief visual inspection. No mechanical failures of the aircraft systems were reported prior to the impact.
Findings
The accident resulted from the pilot's decision to land on a surface that could not support the weight and braking forces of the aircraft. The lack of proper runway preparation or grading at the destination airstrip created hazardous conditions. not injured
Safety message
Pilots must ensure that destination airstrips are adequately prepared and graded before attempting a landing, particularly when moving aircraft to private or newly constructed fields. Visual inspections from the air may not reveal subsurface softness or uneven terrain that can cause loss of control upon touchdown.
