On August 1, 1988, a Mcdonnell Douglas MD-88 (registration N924DL) was involved in an aviation accident near Pensacola, FL. Investigators recorded the probable cause as: The pilot's failure to maintain proper airspeed during the final approach, which resulted in a high-speed touchdown and subsequent runway overrun. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
The aircraft touched down well beyond the intended zone at excessive speed, exceeding its stopping capability and overrunning the end of runway 16.
What happened
The captain reported crossing the final approach fix at an altitude of 3000 feet while continuing the descent for landing. The aircraft made contact with the pavement at a groundspeed of 140 knots, which was significantly higher than the target reference speed. Witnesses and tower personnel confirmed that the aircraft touched down south of the intersection for runways 7-25, with approximately 3000 feet of runway remaining before the end.
Despite the remaining distance, the pilot was unable to bring the plane to a halt within the paved surface. The aircraft continued its momentum past the end of runway 16, resulting in an overrun incident. The landing card indicated that the reference landing speed (Vref) for this specific approach should have been 128 knots, highlighting a substantial deviation from standard operating procedures.
Probable cause
The pilot's failure to maintain proper airspeed during the final approach, which resulted in a high-speed touchdown and subsequent runway overrun.
