Analysis

The airline transport pilot reported that, while on downwind in the traffic pattern, he lowered the landing gear handle and verbally announced “gear down.” He looked at the cockpit indications to verify the landing gear was down and locked; however, he then shifted his attention outside of the cockpit to visually scan for three aircraft approaching and entering the traffic pattern. He reported that he did not confirm the landing gear was down and locked, as he was distracted with scanning for the other traffic. During landing, the bottom of the fuselage sustained substantial damage. A postaccident functional test of the landing gear revealed no
mechanical anomalies with the landing gear system. The pilot reported there were no preimpact mechanical malfunctions or failures with the airframe and engines that would have precluded normal operation.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot’s failure to confirm the landing gear was down before landing due to distraction during the Before Landing checks, which resulted in a gear-up landing. 

Findings

Personnel issues Lack of action - Pilot
Personnel issues Use of equip/system - Pilot
Personnel issues Monitoring equip/instruments - Pilot
Aircraft Main landing gear - Not used/operated
