Diamond Aircraft Ind Gmbh DA 42 NG N607PA accident near Palm Coast, Florida

Probable cause

The pilot’s failure to maintain adequate airspeed, which resulted in a hard landing.

NTSB analysis

During the approach, the designated pilot examiner (DPE) instructed the pilot to demonstrate a short-field landing. While on short final approach, the pilot reduced power and slowed the airspeed. As the airplane crossed the runway threshold, it descended rapidly and then landed hard. Neither pilot reported any flight control anomalies or mechanical malfunctions that would have precluded normal operation. A review of the flight school's training manual revealed that the pilot was to obtain 82 knots indicated airspeed (KIAS) during a short-field landing. Review of the manufacturer's operating procedures revealed that the minimum airspeed for landing was between 84 and 86 KIAS and that it contained no procedures for short-field landings. The DPE stated that the airspeed was between about 75 and 80 KIAS during the approach and 67 KIAS before touchdown, which was lower than the landing airspeed listed in the manufacturer's operating manual or the flight school's training manual. The DPE stated that the speed "bled off" to fast for her to take over control of the airplane. Conducting the landing at such a low airspeed resulted in the loss of lift and a hard landing.
