Accident Details
Probable Cause and Findings
A malfunction of the right brake for reasons that could not be determined because of the perishable evidence, which resulted in the pilot’s inability to maintain directional control of the airplane during landing.
Aircraft Information
Registered Owner (Historical)
Analysis
The pilot reported that the airplane veered sharply to the left when he applied the brakes during the landing roll on a grass airstrip. He applied right rudder to no avail and the airplane continued to the left where the left wing contacted a corn crop. The airplane was pulled into the corn where it came to rest with substantial damage to both wings and the aft fuselage. The pilot reported the airplane’s brakes operated normally prior to takeoff. The brake system consists of main landing gear hydraulic disc brakes which are operated via a mechanical brake lever located on the control stick. The airplane has a steerable nosewheel, but no differential braking. A postaccident inspection of the airplane revealed that hydraulic fluid was present in the brake system. Both brakes functioned when the brake lever was operated, however; the left brake responded quicker than the right brake.
