Probable cause

The pilot's failure to extend the landing gear before landing. Contributing to the accident was the pilot's decision to continue the approach to landing while distracted and his failure to complete the landing checklist.

Findings · 4

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot was landing a retractable landing gear-equipped, twin engine airplane at an uncontrolled airport. While on final approach, an airplane that landed in front of him reported a moose in the vicinity of the runway. An airport maintenance person announced on the common traffic advisory frequency (CTAF) that he was attempting to chase the moose off of the runway. The pilot became distracted trying to avoid wake turbulence from the preceding airplane and monitor the location of the vehicle and moose and failed to extend the landing gear prior to landing. During touchdown, the airplane contacted the runway with the landing gear retracted, and it slid about 1,200 feet. The airplane sustained substantial damage to the fuselage. The pilot stated that there were no preaccident mechanical anomalies with the airplane that would have precluded normal operation.
