Unsafe Condition
Insufficient clearance on the main landing gear (MLG) stabilizer brace, the nacelle A-frame structure, and adjacent electrical wiring harnesses can cause chafing damage. An insufficient fillet radius on the nacelle A-frame structure may also exist, leading to premature cracking and potential failure of the MLG stabilizer brace and loss of MLG down-lock indication.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect the nacelle A-frame structure for insufficient fillet radius and cracking, rework or repair as necessary. Rework the nacelle A-frame structure, including clearance measurements and inspections for fouling or damage. Perform repetitive inspections of the nacelle A-frame structure and MLG stabilizer brace for insufficient clearance and damage, with repair if necessary. Install new stop brackets and a shim on each MLG stabilizer brace assembly. Rework the electrical wiring harnesses in the nacelle area, including conduit inspections and clearance measurements.
