Requires operators of specified Fairchild SA226 and SA227 aircraft to replace Skidmore Wilhelm Model V1-15-1000 brake master cylinders with new or overhauled units overhauled to Fairchild Service Bulletin standards. The directive says this addresses dragging brakes that can overheat and cause wheel‑well fires. Operators must complete the replacement within 200 aircraft hours or 15,000 hours of brake master‑cylinder time (whichever is later) and then repeat overhaul every 15,000 hours (Applicability; Requirement; Compliance).
