SUPPLEMENTARY INFORMATION:  

REGULATORY TEXT:   76-12-05 AVCO LYCOMING: Amendment 39-2635. Applies to all Avco Lycoming T5508D model engines equipped with P/N 2-160-147-02 retaining plate spacers and P/N 2-161-182-01 compressor air bleed bands. Compliance required as indicated.
To prevent partial power loss due to failure of the compressor air bleed band while the engine is operating at a power level which requires the bleed band to be closed, perform the following:
(a) Prior to the first flight of each day, conduct an inspection of the compressor air bleed band for edge wear and cracks, and repair or replace as necessary in accordance with the instructions in Avco Lycoming Service Bulletin, Product Support No. 5508-0003, dated November 30, 1975, or later revision approved by the Chief, Engineering and Manufacturing Branch, FAA, New England Region.
(b) Prior to July 1, 1976, replace P/N 2-160-147-02 retaining plate spacers with P/N 2-160-561-01 retainers and replace P/N 2-161-182-01 compressor air bleed band with P/N 2-161-182-03 compressor air bleed band, in accordance with the instructions in Avco Lycoming Service Bulletin, Product Support No. 5508-0007, dated April 30, 1976, or later revision approved by the Chief, Engineering and Manufacturing Branch, FAA, New England Region.
(c) Equivalent methods of compliance may be approved by the Chief, Engineering and Manufacturing Branch, FAA, New England Region.
The manufacturer's Service Bulletins identified and described in this directive are incorporated herein and made a part hereof pursuant to 5 U.S.C. 552(a)(1). All persons affected by this directive who have not already received these documents from the manufacturer may obtain copies upon request to Avco Lycoming Engine Group, Stratford Division, 550 South Main Street, Stratford, Connecticut 06497. These documents may also be examined at the Office of the Regional Counsel, New England Region, FAA, 12 New England Executive Park, Burlington, Massachusetts 01803, and at FAA Headquarters, 800 Independence Avenue, S.W., Washington, D.C. A historical file on this AD which includes the incorporated material in full is maintained by the FAA at its headquarters in Washington, D.C., and at the New England Regional Office in Burlington, Massachusetts.
This amendment becomes effective June 23, 1976.
