NOTE: The manufacturer has installed the P/N 638223 gasket on some serial numbers of the remanufactured engines listed herein. These engines are identified by a white paint band around the aneroid housing. Notation of compliance with Paragraph B may be made in the maintenance records of these engines without further action.
Compliance: Required as indicated, unless already accomplished.
To prevent extrusion of P/N 632647 gasket and/or fuel leakage at the top edge of the variable orifice body, accomplish the following or any equivalent procedure approved by the Chief, Engineering and Manufacturing Branch, FAA, Central Region, Kansas City, Missouri:
A) Within 25 hours' time-in-service after the effective date of this AD, and thereafter at intervals of 100 hours' time-in-service, visually inspect the fuel injection pump in the area of the top edge of the variable orifice body for evidence of fuel leakage and/or extrusion of P/N 632647 gasket. In making this inspection, snip the cooling shroud inboard of the elbow fitting 3/8 inch vertically and bend up the bottom edge of the shroud to permit access to the area to be inspected.
B) If the inspection required by Paragraph A discloses leakage and/or gasket extrusion, prior to further flight, replace P/N 632647 gasket with P/N 638223 gasket in accordance with Teledyne Continental Motors Service Bulletin M70-17 dated April 1, 1971 or later FAA approved revision.
C) Upon accomplishment of the replacement provided in Paragraph B, compliance with the provisions of Paragraph A is no longer required.
Teledyne Continental Motors Service Bulletin M70-17 dated April 1, 1971, or later FAA approved revision, refers to this subject.
This amendment becomes effective April 29, 1971.
