Aircraft involved
Probable cause & findings
The flight crew's failure to extend the landing gear, which resulted in an inadvertent wheels up landing. Contributing to the accident was the flight crew's diverted attention.
Factual narrative
According to the captain, while on approach to land, he distracted the crew by pointing out a boat dock. He said that after touchdown, he realized that the landing gear was not extended, and the airplane slid on its belly, sustaining substantial damage to the underside of the fuselage. In the captain's written statement to the NTSB, he reported that there were no preaccident mechanical problems with the airplane, but indicated that the flight crew did not hear the landing gear retracted warning horn. The captain also stated that the accident could have been prevented if he had not distracted the crew.
