Aircraft involved
Probable cause & findings
The pilot’s failure to extend the landing gear during the approach and landing.
Factual narrative
The airline transport pilot and private pilot rated passenger departed on a local, personal flight. The pilot reported that he failed to extend the landing gear before landing. The airplane sustained substantial damage to the fuselage ribs and stringers. He said that the landing gear warning did not sound through the headsets, so the sound was faint and that the gear warning sounded like the stall warning, which was “confusing.” The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
