NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: CONDUCT A DIRECTED SAFETY INVESTIGATION OF THE FAIRCHILD SA-226 AND SA-227 WHEEL BRAKING SYSTEMS THAT UTILIZE THE B.F. GOODRICH 2-1203-3 WHEEL BRAKE ASSEMBLY TO: (1) DETERMINE THE POTENTIAL FOR BRAKE LOCKUPS OR OVERHEATING AS A RESULT OF PISTON INSULATOR COCKING; AND (2) EVALUATE THE CURRENT WEAR LIMITS FOR PROPER BRAKE OPERATION AT THE MAXIMUM WEAR ALLOWED.
In plain language (FlightFinder summary)
The NTSB asks the FAA to launch a directed safety investigation of the Fairchild SA-226 and SA-227 wheel braking systems using the B.F. Goodrich 2-1203-3 wheel brake assembly. The investigation should determine whether piston insulator cocking could lead to brake lockups or overheating, and evaluate if the current wear limits ensure proper brake operation at maximum allowable wear.
