To prevent continued use of certain Stewart Warner oil coolers which may be defective, accomplish the following:

(a) Remove the cowl assembly as necessary to gain access to the oil cooler.

(b) Check the oil cooler model number and serial number. Oil cooler model and serial numbers are ink stamped on the side of the cooler with the serial number following the model number.

1. If the oil cooler is either model number 10568B with serial number 101 through 579 or model number 10578B with serial number 101 through 634, or if the model or serial number is illegible, remove and replace it with an oil cooler not of the above model and serial numbers.

2. If the oil cooler is neither model number 10568B with serial number 101 through 579 nor model number 10578B with serial number 101 through 634, make the record entry required in paragraph (c).

(c) The inspection and maintenance record entry in paragraph (b)2. may be accomplished by holder of a pilot's certificate issued under Part 61 of the Federal Aviation Regulations on any aircraft owned or operated by him.

(d) Any equivalent methods of compliance with this AD must be approved by the Chief, Engineering and Manufacturing Branch, FAA, Southern Region.

NOTE: A ferry flight to accomplish a needed oil cooler replacement may be issued under the provision of FAR 21.197 by FAA Flight Standards District Offices.

Grumman American Service Bulletin Number 156 pertains to this subject.

This amendment becomes effective November 10, 1976, to all persons except those to whom it was made effective earlier by airmail letters issued on October 18, 1976.
