Models named: AS332C, L, L1. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
Model AS332C, L, and L1 helicopters, certificated in any category. Note 1: This AD applies to each helicopter identified in the preceding applicability provision, regardless of whether it has been otherwise modified, altered, or repaired in the area subject to the requirements of this AD. 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 (b) 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 within 300 hours time-in-service (TIS) or within the next 3 calendar months, whichever occurs first, unless accomplished previously. To prevent loss of electrical continuity, which could cause loss of critical systems, and subsequent loss of control of the helicopter, accomplish the following: (a) Remove and replace each ``CONNECTRAL'' green electrical module that does not have a white dot on the face and that has a manufacturing code 95/16 through 96/21 engraved on a side, with an airworthy electrical module. Those manufacturing codes identify modules manufactured between the beginning of the 16th week of 1995 and the end of the 21st week of 1996. Note 1: Eurocopter France Service Bulletin No. 01.00.51, dated May 4, 1998, pertains to the subject of this AD. (b) 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, Regulations Group, Rotorcraft Directorate, FAA. Operators shall submit their requests through an FAA Principal Maintenance Inspector, who may concur or comment and then send it to the Manager, Regulations Group. Note 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Regulations Group. (c) Special flight permits may be issued in accordance with sections 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the helicopter to a location where the requirements of this AD can be accomplished. (d) This amendment becomes effective on November 30, 1999. Note 3: The subject of this AD is addressed in Direction Generale De L'Aviation Civile (France) AD No. 98-254-070(A), dated July 1, 1998. Issued in Fort Worth, Texas, on October 18, 1999. Eric Bries, Acting Manager, Rotorcraft Directorate, Aircraft Certification Service. [FR Doc. 99-27791 Filed 10-25-99; 8:45 am] BILLING CODE 4910-13-P
