What happened
During the initial climb phase of a local flight, the pilot reported that the aircraft failed to gain altitude as it lifted off the runway. Instead of climbing, the plane settled back onto the pavement and began to drift toward the left side of the runway. In an attempt to maintain control or stop the slide, the pilot applied wheel braking. This action, combined with the unstable surface, caused the landing gear to collapse, resulting in the aircraft flipping completely inverted.
The investigation
Following the accident, an FAA airworthiness inspector conducted a thorough examination of the wreckage. The inspection revealed no evidence of pre-impact mechanical failures or irregularities with the aircraft systems. The primary damage was consistent with the violent inversion and ground impact rather than a pre-existing defect.
Findings
The investigation identified several contributing factors to the accident sequence. The runway surface condition was cited as poor, specifically noting the presence of loose gravel which likely reduced traction and stability during the critical takeoff roll. Additionally, environmental conditions included a surface wind blowing from the right rear at 6 knots, which may have influenced the aircraft's lateral movement. The pilot also noted these surface conditions as a significant factor in the loss of control.
Safety message
This accident highlights the critical importance of runway surface conditions during takeoff operations. Pilots must carefully evaluate runway quality, particularly regarding loose debris or gravel, which can compromise braking effectiveness and directional control during high-speed ground rolls.
