What happened
The pilot of the jet reported that he elected to fly the aircraft at a final approach speed exceeding normal parameters. This decision contributed to the airplane touching down significantly beyond the intended touchdown zone. The aircraft landed long and subsequently overran the end of the runway.
Examination of the crash site indicated that the airplane touched down 2,304 feet from the approach end of the runway. The runway in question was 4,000 feet in length. Performance charts for this specific aircraft type show that a standard final approach speed of 108 knots would provide sufficient capability to stop within 2,650 feet.
The investigation
The investigation focused on the pilot's account of the flight and the physical evidence at the crash site. The discrepancy between the normal stopping distance and the actual touchdown point was analyzed against performance data.
