For helicopters that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (d) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.

Compliance

Required as indicated, unless accomplished previously. To prevent power loss due to fuel starvation, which could cause one or both engines to flameout and a subsequent forced landing, accomplish the following: (a) Within 25 hours time-in-service (TIS) and after any subsequent flight during which either or both fuel filter clogged caution lights illuminate: (1) Verify that the fuel filter by-pass valve (valve) is correctly closed in each engine fuel filter in accordance with paragraph CC.1), Eurocopter France Service Telex 00067 (Service Bulletin No. 01.00.56), dated July 24, 1998 (SB). (2) If a valve is jammed (open or closed), clean the valve in accordance with paragraph CC.2)B) of the SB or replace the valve with an airworthy valve. Repeat the requirements of paragraph (a)(1) of this AD. (3) Conduct a ``filter'' clogging warning test (test) in accordance with paragraphs CC.2), CC.2)A) and CC.2)B) of the SB. (4) If a jammed valve (open or closed) is detected during the test, clean the valve in accordance with paragraph CC.2)B) of the SB or replace the valve with an airworthy valve. Repeat the requirements of paragraph (a)(3) of this AD. (5) When the test result is satisfactory, repeat the requirements of paragraph (a)(1) of this AD. (b) Within 25 hours TIS, insert a copy of this AD into the Rotorcraft Flight Manual (RFM) or make the following pen and ink addition to the RFM Emergency Procedure for fuel filter clogged caution light illumination: ``If both fuel filter clogged caution lights illuminate, land as soon as practicable.'' (c) If both filter clogged caution lights illuminate, after landing, either: (1) Accomplish the requirements of paragraph (a) of this AD before further flight, or, (2) Replace both filter cartridges with airworthy filter cartridges and fly to a location where the requirements of paragraph (a) of this AD must be accomplished before further flight. (d) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Rotorcraft Standards Staff, FAA. Operators shall submit their requests through a FAA Principal Maintenance Inspector, who may concur or comment and then send it to the Manager, Rotorcraft Standards Staff. Note 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Manager, Rotorcraft Standards Staff. (e) Special flight permits will not be issued. (f) The inspection shall be done in accordance with Eurocopter France Service Telex 00067, dated July 24, 1998, (Service Bulletin No. 01.00.56). This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51.
