Probable cause
A complete failure of the brake system due to a crack in the brake lines. Contributing to the accident was that the brakes were not adequately maintained by company maintenance personnel.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
During the landing roll, the pilot applied full brakes. The pilot then lost directional control and the airplane nosed over on its back. Examination of the brake system revealed a stress crack under the sleeve which caused a complete loss of brake fluid when the brakes were applied by the pilot.
