On July 3, 1991, a Cessna 185F (registration N222WH) operated by William D. Hansen was involved in an aviation accident near Farewell, AK. No fatalities were reported. Investigators recorded the probable cause as: A broken brake line that caused a loss of hydraulic pressure to the left main landing gear brake, resulting in ineffective braking during the landing roll. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
The pilot reported ineffective left brakes during landing rollout, leading to a sharp right swerve. The left main gear collapsed and the wing struck the ground.
What happened
During the landing roll, the pilot experienced a loss of braking effectiveness on the left side of the aircraft. This failure prevented the airplane from maintaining its runway centerline, causing it to swerve sharply to the right. The impact resulted in the collapse of the left main landing gear and contact between the left wing and the ground.
The investigation
Post-incident examination revealed a broken brake line within the hydraulic system. After the damaged line was replaced and the system was properly serviced, the brakes functioned normally, confirming that the initial failure was mechanical rather than structural or operational in nature.
Probable cause
A broken brake line that caused a loss of hydraulic pressure to the left main landing gear brake, resulting in ineffective braking during the landing roll.
