Compliance: Required as indicated unless already accomplished.

To reduce the possibility of engine torque oscillations resulting from improperly set propeller RPM levers and to provide remedial procedures if such a situation does occur from any cause, accomplish the following:

(a) For airplanes with in-service engines, within the next 50 hours time-in-service after the effective date of this AD, or prior to further flight for airplanes when any overhauled or replacement engine or propeller governor is installed, check the propeller governor low RPM setting as described in Section 2, Accomplishment Instructions, of Garrett Engine Division (GED) Service Bulletin (SB) TPE331-76-0023, Revision 1, dated May 6, 1988.

(1) If the low RPM setting is in between 95.5 percent to 96 percent, inclusive, no further action is required per this paragraph of the AD unless a replacement engine or propeller governor is subsequently installed.

(2) If the low RPM setting is not in between 95.5 percent or 96 percent inclusive, prior to further flight adjust the low RPM setting to the range of 95.5 percent to 96 percent as described in the above SB.

(b) Within 7 calendar days from the effective date of the AD, insert Advance Amendment Bulletin No. 1, dated April 13, 1988, into the Airplane Flight Manual, BAe Document No. HP.4.10, facing Page 4, Section 3, and operate the airplane accordingly.

(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 Staff, AEU-100, Europe, Africa and Middle East Office, FAA, c/o American Embassy, B-1000, Brussels, Belgium; Telephone (322) 513.3830 ext. 2710/2711.

All persons affected by this directive may obtain copies of the appropriate document(s) referred to herein upon request to Garrett Engine Division, Post Office Box 5217, Phoenix, Arizona 85010; Telephone (602) 225-2548, or British Aerospace, Technical Librarian, Post Office Box 17414, Dulles International Airport, Washington, D.C. 20041; Telephone (703) 435- 9100; or may examine these documents at the FAA, Office of the Regional Counsel, Room 1558, 601 East 12th Street, Kansas City, Missouri 64106.
