On June 17, 2002, a Cessna 180K (registration N66471) was involved in an aviation accident near Helena, MT. Investigators recorded the probable cause as: Binding brakes for undetermined reasons and the pilot's failure to maintain directional control during an aborted takeoff. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
During takeoff on a 2,980-foot asphalt runway, the pilot of a Cessna 180K aborted due to perceived inadequate power. Brake application resulted in a left grab, veer, and collapse of the right main landing gear.
Accident Details
The accident involved a Cessna 180K aircraft during the takeoff roll on a 2,980-foot long asphalt runway. Wind conditions were calm at the time.
Sequence of Events
The pilot elected to abort the takeoff due to a perceived inadequate power situation. During the aborted takeoff, the pilot applied the brakes but initially received no response. Subsequently, the pilot applied the brakes more firmly, at which point the left brake grabbed, causing the aircraft to veer to the left. The pilot was unable to maintain directional control, and the aircraft's right main landing gear collapsed.
Post-Crash Examination
A post-crash examination of the aircraft's wheels and brakes revealed that both brake discs appeared to be overheated. The left wheel still rotated and stopped with the application of the left brake. The right brake could not be tested in this manner as it had separated from the airframe. The parking brake was found disengaged and functioned satisfactorily following the accident.
