Unsafe Condition
Failure of the aileron control cables due to broken wires or wear reducing cable cross section area.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect aileron control cables within 100 hours time in service after the effective date, and every 600 hours time in service or 12 months, whichever comes first. Replace cables if more than three wires are broken; shorten inspection intervals to 100 hours if four to six wires are broken, or replace immediately if more than six wires broken or equivalent wear.
AI-generated summary from the source AD text. Verify against the official source before acting.
Compliance Time
Within the next 100 hours time in service after the effective date of this AD, unless already accomplished within the last 500 hours time in service, and thereafter at intervals not to exceed 600 hours time in service or 12 months, whichever occurs first.

ADDRESSES: FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: REGULATORY TEXT: 71-25-04 NORTH AMERICAN ROCKWELL: Amendment 39-1352. Applies to Models NA-265, NA-265-20, NA-265-30, NA-265-40, NA-265-60, NA-265-70. Compliance required as indicated. To prevent failure of the aileron control cables, accomplish the following: Within the next 100 hours time in service after the effective date of this AD, unless already accomplished within the last 500 hours time in service, and thereafter at intervals not to exceed 600 hours time in service or 12 months, whichever occurs first, inspect the aileron control cables and replace as necessary; provided however that, if as a result of any inspection, more than three wires are found to be broken, the repetitive inspection interval will be decreased, or replacement required, as follows: (a) With four to six wires broken, repeat the inspection at intervals not to exceed 100 hours time in service. (b) With more than six wires broken, or if an equivalent reduction to the cable cross section area is present due to wear, replace the cable with a new or serviceable cable before further flight. Inspect the aileron control cables (P/N's 246-52324, 246-52325, 246-52339, 276-523005- 11, 276-523006-11, 276-523008-11, as applicable) in accordance with the following instructions: 1. Remove aileron control cables from the aircraft and inspect per step 9 or follow steps 2 through 16. 2. Lower wing flaps. 3. Open main wheel well doors or remove both wheel well cover assemblies as applicable. NOTE: Use normal safety precautions such as disconnecting the batteries to prevent inadvertent wing flap or landing gear wheel well door actuation. 4. In the left hand wheel well, disconnect the lower left hand aileron cable turnbuckle. 5. In the right hand wheel well, disconnect the upper left hand cable from the left hand aileron sector (P/N 246-52314). 6. Disconnect the left hand outboard aileron sector (P/N 246-52305-1), accessible through the left hand flap well, by removing the sector pivot bolt. 7. With the aileron sector pivot bolt removed disconnect the upper & lower left hand aileron cables from the sector. 8. Cable slack will now be available to allow pulling the upper left hand cable down into the landing gear strut well for inspection per step 9. 9. Clean the cable for a visual inspection. The cables must be bent in a "U" and inspected with a four power, or greater, magnifying glass in the area of pulley contact. 10. The lower left hand aileron control cable must be pulled inboard into the wheel well for inspection of the cable that passes over the pulley. Inspect per Step 9. 11. If the inspection of the left hand aileron control cables shows that they do not require replacing, reconnect and rig the left hand aileron control cables (See Note, below). 12. Disconnect the lower right had aileron cable turnbuckle located in the right hand wheel well. 13. Disconnect the upper cable at the aileron sector (P/N 246-52364) located in the right hand wheel well. 14. Pull the upper aileron cable down into the right hand main landing gear strut well and inspect per step 9. 15. Pull the lower aileron control cable into the right hand wheel well and inspect per step 9. 16. If the inspection of the two right hand cables reveals that they do not require replacing, reconnect and rig the aileron control system (See Note, below). NOTE: Instructions pertaining to the installation of new or serviceable cables and the rigging of the aileron control system are contained in the applicable maintenance documents. This amendment becomes effective December 4, 1971. FOOTER:
