Unsafe Condition

Potential fire hazard due to fuel leaks, wetting, fuel stains, and/or fumes at inboard areas of both wings and in the cabin area caused by improper torque or dimensional non-compliance of Parker-Hannifin unions and fittings.

AI-generated summary from the source AD text. Verify against the official source before acting.

Required Actions

Inspect for fuel leaks and evidence prior to next flight and each subsequent flight until compliance with paragraphs (b)(1) through (b)(7). If leaks are found, access Parker-Hannifin unions, torque to Table I specifications, measure dimensions, and if non-compliant, replace fittings using AN fittings, Piper preseated tubes, or Parker-Hannifin unions with specific torque instructions. Perform fuel tank tests, re-inspect, and correct as necessary. Record all actions.
