Note 1: This AD applies to each sailplane 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 sailplanes 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 in the body of this AD, unless already accomplished. To detect and correct loose forward elevator mounting brackets, which could result in these brackets separating from the sailplane with consequent loss of control of the sailplane, accomplish the following: (a) Within the next 30 calendar days after the effective date of this AD, and thereafter at intervals not to exceed 12 calendar months, inspect the forward elevator mounting bracket for looseness. Apply a torque of 130 inches/pounds on the elevator mounting bracket and do not apply a force to the bonded in-ball. Accomplish the inspections in accordance with the Material and Instructions section of Rolladen Schneider Technical Bulletin No. 3043/4035, dated July 14, 1993. (b) If any loose forward elevator mounting bracket is found during any inspection required by this AD, prior to further flight, modify the area and install a new forward elevator mounting bracket in accordance with Rolladen Schneider BA-4 Instructions, dated July 7, 1993, as referenced in Rolladen Schneider Technical Bulletin No. 3043/4035, dated July 14, 1993. Continue to reinspect as specified in paragraph (a) of this AD at intervals not to exceed 12 calendar months. (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 sailplane to a location where the requirements of this AD can be accomplished. (d) An alternative method of compliance or adjustment of the initial or repetitive compliance times that provides an equivalent level of safety may be approved by the Manager, Small Airplane Directorate, 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.
