REGULATORY TEXT:  
89-03-03 PARTENAVIA COSTRUZIONI AERONAUTICHE, SPA: Amendment 39-6117.

Applicability: Models P 68, P 68B, P 68C, P 68TC, P 68 "Observer", and P 68TC "Observer" (all serial numbers) airplanes certificated in any category.

Compliance: Required within the next 25 hours time-in-service (TIS) after the effective date of this AD, unless already accomplished after the last engine removal.

To prevent loss of structural integrity of the engine mounts, accomplish the following as referenced in Partenavia Service Bulletin (SB) No. 76 dated December 23, 1988:

(a) Inspect the engine mounting system as follows for both engines:

(1) Prepare the airplane as necessary as described for "ENGINE REMOVAL" in the Partenavia Maintenance Manual and support the engine with a hoist.

(2) Remove the mount bolts (P/N MS 20006-12) from the airframe one-by-one starting with the lower bolts.

(3) With a 10x magnifier, visually inspect the bolts for cracks, circumferential scoring, corrosion, or absence of protective coating on the shank of the bolt. Prior to further flight discard all damaged bolts, and replace with serviceable bolts.

(4) Insure that washers (P/N MS 20002-C6) are properly installed on all the engine mount attachment bolts with the chamfer in the hole mating with the head of the bolt.

(5) Reinstall undamaged bolts or replacement bolts and washers. Starting with the upper bolts, torque each to 335 to 375 inch-pounds.

(6) Prepare the airplane for flight as described in "INSTALLATION OF ENGINE" in the Partenavia Maintenance Manual.

(b) Repeat the requirements of paragraph (a) of this AD at any subsequent engine removal.

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

(d) An equivalent means of compliance with this AD may be used if approved by the Manager, Aircraft Certification Division, 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; telephone 81 759-0946; or may examine this document at the FAA, Office of the Assistant Chief Counsel, Room 1558, 601 East 12th Street, Kansas City, Missouri 64106.

This amendment (39-6117, AD 89-03-03) becomes effective on February 16, 1989.
