Aircraft Accident/Incident Report
Terrell, Texas 75160
Sunday, July 7, 1996 10:30 CDT
NTSB Narrative Summary Released at Completion of Accident
During a repair of the airplane's left brake, the mechanic manufactured a hydraulic brake line and installed it; however, he did not bleed the brake nor perform a landing gear retraction test. A second mechanic was hired to add brake fluid and bleed the brake. The private pilot hired a flight instructor to get him current and qualified in the airplane, which he was purchasing. The flight instructor was also an A&P mechanic, and he was requested to check out the airplane for maintenance defects. During taxi, the flight instructor determined the left brake needed further bleeding; however, it operated satisfactory. After completing three touch and go landings, the private pilot flew the airplane to Air Park East Airport to correct all maintenance anomalies found during the flight. During the landing roll on runway 13, with the flight instructor manipulating the controls, the left brake failed, and the airplane overran the departure end of the runway, separating its nose landing gear and damaging the fire wall. Examination of the airplane revealed that the left brake line was fractured where it had been chaffing.
NTSB Probable Cause Narrative
the mechanic's improper installation of the left main landing gear brake line, which resulted in chaffing and failure of the brake line, loss of hydraulic fluid, and inoperative brake(s).
