(1) If no discrepancy is found, return the airplane to service.

(2) If a discrepancy is found, prior to further flight, accomplish the following:

(i) Replace damaged oil tube. Carefully inspect and, if necessary, replace the aileron control cable.

(ii) To prevent further interference between the brake oil lines and the aileron control cable, install a clamp (MS 21919-DG9) as shown in figure 2 on page 3/3 of S/B No. 68.

(iii) Visually check that the clamp is properly installed and the interference is no longer present.

(iv) Return the airplane to service.

(b) For airplanes with S/N 299 to 340 inclusive:

(1) Remove carpeting from around the photogrammetric hatch.

(2) Cut a rectangular inspection hole 3.35 inches by 2.35 inches (85 x 60mm) in accordance with figures 1 and 2 on page 3/3 of S/B No. 68.

(3) Manufacture a rectangular cover plate for the above inspection hole in accordance with figure 2 on page 3/3 of S/B No. 68.

(4) Visually inspect the aileron cable to the right of the photogrammetric hatch for interference with the brake oil line in accordance with steps 3 through 6 of Part 1A, "INSPECTION INSTRUCTIONS" of S/B No. 68.

(i) If no discrepancy is found, return the airplane to service.

(ii) If a discrepancy is found, prior to further flight, accomplish paragraph (a)(2) of this AD.

(c) For all aircraft having clamp (P/N MS 21919-DG9) installed on the brake oil line in accordance with Part II, "Repair Instructions" of Partenavia S/B No. 68 dated January 31, 1986, no further action is necessary.

(d) Airplanes may be flown in accordance with FAR 21.197 to a location where this AD may be accomplished.

(e) An equivalent means of compliance with this AD may be used if approved by the Manager, Aircraft Certification Staff, AEU-100, Europe, Africa and Middle East Office, FAA, c/o American Embassy, B-1000 Brussels, Belgium.

All persons affected by this directive may obtain copies of the document referred to herein upon request to Partenavia Costruzioni Aeronautiche S.p.A., Via Cava, 80026 Casoria (Naples), Italy; or FAA, Office of the Regional Counsel, Room 1558, 601 East 12th Street, Kansas City, Missouri 64106.
