What happened
During the final approach phase, the pilot executed a landing that was both lengthy and fast, touching down at approximately 75 knots. The aircraft came to rest well past the intended touchdown zone. As the plane rolled out, the pilot encountered a significant hump in the runway surface. This topographical feature created a blind spot, completely obstructing the pilot's view of the runway end.
Recognizing that the remaining distance was insufficient to stop safely, the pilot determined it was too late to abort the landing or attempt a go-around. Despite efforts to decelerate, the aircraft could not halt within the available pavement. It continued past the departure end of the runway and subsequently nosed over.
The investigation
The primary mechanical finding centered on the runway geometry. Investigators noted that a hump in the runway surface was present at the location where the aircraft had landed. This physical obstruction was critical to the sequence of events because it blocked the pilot's forward vision, preventing early detection of the runway terminus.
Findings
The accident was caused by a combination of operational and environmental factors. The pilot landed too far down the runway at an excessive speed, leaving minimal margin for error. The presence of the hump in the runway further compromised safety by obstructing the view of the end, which delayed the realization that stopping was impossible until it was too late.
Safety message
Pilots should be aware that runway surface irregularities can significantly impair visibility of the runway end. Landing long and fast reduces the ability to react to such obstructions. Maintaining proper airspeed and touchdown point is critical for ensuring adequate stopping distance, especially on runways with known or unexpected topographical features.
