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 [[Page 64606]] 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.

Required within the next 3 calendar months after the effective date of this AD, unless already accomplished. To prevent the airbrake from inadvertently deploying during high g maneuvers, which could result in an overstressing effect on the airframe with consequent reduced sailplane control, accomplish the following: (a) Replace the airbrake lever in accordance with Ursula Technical Bulletin 101-25/2, dated January 21, 1998, and drawing No. 101-44-3(2), as referenced in the technical bulletin.

(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, 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.
