99-09-07 S.N. CENTRAIR: Amendment 39-11140; Docket No. 98-CE-50-AD. Applicability: Models 101, 101A, 101P, and 101AP gliders, all serial numbers, certificated in any category, that have modification 101-24 (major cockpit configuration equipped on all gliders manufactured since 1990) incorporated, and do not have modification 101-21 (minor modifications to this cockpit configuration) incorporated. NOTE 1: This AD applies to each glider identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For gliders 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 (c) 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 the next 3 calendar months after the effective date of this AD, unless already accomplished. To prevent elevator flight control interference caused by an unsecured battery discharge warning device, which could result in reduced or loss of glider control, accomplish the following: (a) Secure the battery discharge warning device by installing an attachment lug (part number $Y986A or an FAA-approved equivalent part number) to the supporting bracket. Accomplish this installation in accordance with CENTRAIR Service Bulletin No. 101-19, Revision 1, dated May 20, 1997. (b) 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 glider to a location where the requirements of this AD can be accomplished. (c) An alternative method of compliance or adjustment of the compliance time that provides an equivalent level of safety may be approved by the Manager, Small Airplane Directorate, Aircraft Certification Service, 1201 Walnut, suite 900, Kansas City, Missouri 64106. The request shall be forwarded through an appropriate FAA Maintenance Inspector, who may add comments and then send it to the Manager, Small Airplane Directorate. NOTE 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Small Airplane Directorate. (d) Questions or technical information related to CENTRAIR Service Bulletin No. 101-19, Revision 1, dated May 20, 1997, should be directed to S.N.
