What happened
The pilot elected to execute a precautionary landing on a runway measuring 2,520 feet in length, which featured a displaced threshold caused by trees at the approach end. The decision was driven by deteriorating weather conditions encountered during the flight.
Upon touchdown, the aircraft landed approximately 500 feet down the usable portion of the runway. Immediately after contact with the pavement, the aircraft bounced between five and six times. Following these bounces, the pilot raised the flaps in an attempt to recover control or reduce drag. However, the aircraft failed to stop within the available distance and skidded off the departure end of the runway.
The investigation
The Federal Aviation Administration (FAA) reviewed the incident and determined that the pilot had landed long, exceeding the optimal touchdown zone for the available runway length. Additionally, a tailwind was present during the landing phase, which further increased the ground roll distance required to stop the aircraft safely.
Findings
Contributing factors included the combination of a displaced threshold reducing the effective landing distance, the pilot's decision to land long, and the presence of a tailwind. The bouncing motion upon initial touchdown compromised the pilot's ability to maintain directional control and stop the aircraft before the end of the pavement.
Safety message
Pilots should carefully evaluate runway length availability, including displaced thresholds, when planning for precautionary landings in deteriorating weather. Landing long with a tailwind significantly increases stopping distance requirements and reduces the margin for error during ground operations.
