Unsafe Condition

Loss of the fuel injection pump adjustable bypass needle with subsequent power failure.

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

Required Actions

Visually inspect the fuel injection pump for a hexagonal head brass plug with a stainless steel adjusting needle. If the needle's slotted head is flush or below the plug face, secure it with epoxy. If the needle extends beyond the plug, replace it with P/N 637766 or 637767, use a new 'O' ring, adjust to previous settings, and safety wire the needle. Follow Teledyne Service Bulletin or FAA-approved procedures.
