Aviation Accident Summary ANC90LA113

BUTTERFLY LAKE, AK, USA

Aircraft #1

N3125W

CESSNA 180B

Analysis

THE PILOT REPORTED THAT HE FORGOT TO RETRACT THE WHEEL PORTION OF HIS AMPHIBIOUS FLOAT EQUIPPED AIRPLANE FOLLOWING A TAKEOFF FROM A HARD SURFACED RUNWAY. SHORTLY THEREAFTER, HE LANDED IN THE WATER WITH THE WHEELS EXTENDED AND IMMEDIATELY NOSED OVER. THE PILOT SAID THAT HE FELT RUSHED DURING HIS PRECEDING TAKEOFF DUE TO A POTENTIAL AIR TRAFFIC CONFLICT, AND HE SUSPECTS THAT HIS CONCERN FOR THE LOCATION OF THE APPROACHING TRAFFIC INTERRUPTED HIS NORMAL HABIT OF RETRACTING THE GEAR.

Probable Cause and Findings

THE PILOT FAILED TO RETRACT THE AIRPLANE'S WHEEL PRIOR TO A WATER LANDING. CONTRIBUTING FACTORS ARE HIS FAILURE TO FOLLOW ESTABLISHED PROCEDURES/DIRECTIVES, AND HABIT INTERFERENCE CAUSED BY HIS CONCERN OVER AN AIR TRAFFIC CONFLICT DURING THE PRECEDING TAKEOFF.
