On 24 Apr 2013, a CESSNA U206G operated by BIK AIR was involved in an aviation accident near Nenana, AK. No fatalities were reported. Investigators recorded the probable cause as: Ice accretion in the right main landing gear wheel brake during departure, which prevented the right main landing gear from rotating on landing and resulted in a runway excursion and subsequent impact with a snow bank. This summary draws on records from NTSB; 12 related events involving the same aircraft type or operator are linked below.
A pilot reported that after taxiing through snow and slush, the airplane veered right on landing. Postaccident examination revealed the right brake was locked by ice.
Incident Summary
The pilot reported that the airplane had taxied through loose snow and slush at the departure airport. The subsequent flight and landing occurred in sub-freezing temperatures. Upon touchdown at the destination airport, the airplane veered to the right. The pilot applied left rudder in an attempt to correct the veer, but the airplane then veered sharply to the right, nosed down, and impacted a snow berm. The left wing sustained substantial damage.
Examination Findings
A postaccident examination conducted by the pilot found the right brake still locked by ice and the left brake free. The pilot then disassembled the right brake, and no mechanical anomalies were found.
