REGULATORY TEXT:   93-14-15 AVCO LYCOMING: Amendment 39-8639. Docket No. 91-ANE-30.
Applicability: Lycoming Model IO-360-A1B6D and IO-360-A3B6D engines, modified per Aircraft Design, Inc., STC SE4757NM; installed on Mooney M20J, modified per Aircraft Design, Inc., STC SA4758NM.
Compliance: Required within 30 days after the effective date of this AD, unless accomplished previously.
To prevent possible premature engine failure, accomplish the following:
(a) Fabricate and install on the instrument panel a placard, in accordance with FAR 23.1541(b), stating "DO NOT OPERATE ENGINE ABOVE 33.0 IN Hg."
(b) Re-mark the manifold pressure gauge by removing the radial red line at 38.5 Hg and placing the radial red line at 33.0 Hg.
(c) Revise the Limitations and Normal Procedure Sections of the Aircraft Flight Manual Supplement as follows:
(1) Delete "38.5" Hg" as it appears in these sections and insert in lieu thereof "33.0" Hg."
(2) Delete "36.0 Hg" as it appears in Normal Climb Throttle and insert in lieu thereof "33.0 Hg."
(d) Attach this AD as a permanent appendix to the Aircraft Flight Manual.
(e) An alternative method of compliance, or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, Seattle Aircraft Certification Office. The request shall be forwarded through an appropriate FAA Principal Maintenance Inspector, who may concur or comment and then send it to the Manager, Seattle Aircraft Certification Office.
NOTE: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Seattle Aircraft Certification Office.
(f) Special flight permits may be issued, in accordance with FAR 21.197 and 21.199, to ferry the aircraft to a location where the requirements of this AD can be accomplished.
(g) This amendment becomes effective on August 23, 1993.
