What happened
The commercial pilot and flight instructor was attempting to land at a private turf airstrip when she reportedly encountered the outflow from a thunderstorm located approximately one mile away. Despite the adverse weather conditions, the pilot elected to continue with the landing attempt. The aircraft touched down with a greater than desired ground speed. While the airplane was still decelerating at the far end of the strip, it encountered a mud hole and nosed over.
The investigation
The investigation focused on the circumstances surrounding the landing and the subsequent damage to the aircraft. The pilot reported encountering thunderstorm outflow during the final approach. The touchdown occurred with excessive ground speed, which contributed to the difficulty in controlling the aircraft on the wet turf surface. The presence of a mud hole at the end of the runway further exacerbated the situation, leading to the nose-over.
Findings
Contributing factors included the adverse weather conditions, specifically the thunderstorm outflow, and the pilot's decision to continue the landing despite these conditions. The excessive ground speed at touchdown reduced the effectiveness of braking and control inputs. The wet turf surface and the presence of a mud hole were significant environmental factors that led to the loss of control.
Safety message
Pilots should exercise extreme caution when landing in adverse weather conditions, particularly near thunderstorms. Deciding to abort a landing or divert to another airport may be safer than continuing into deteriorating conditions. Additionally, pilots should be aware of runway surface conditions and avoid areas with standing water or mud holes.
