Applicability*9
Models N22B, N22S, and N24A airplanes (all serial numbers), certificated in any category. Note 1: This AD applies to each airplane 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 airplanes 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 (e) 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 prevent contamination in the aft wing break connectors, which could result in uncommanded flap extensions and incorrect stall warning indications with consequent loss of airplane control, accomplish the following: (a) Within the next 100 hours time-in-service (TIS) after the effective date of this AD and thereafter at intervals not to exceed 300 hours TIS, inspect the aft wing break connectors for arcing damage, deposits between contacts, and looseness of contacts. Accomplish these inspections in accordance with the ACCOMPLISHMENT INSTRUCTIONS section of Nomad Alert Service Bulletin ANMD-57-13, dated October 30, 1995. (b) If any deposits between contacts, loose contacts, or aft wing break connector arcing damage is found, prior to further flight, accomplish the following, as applicable, in accordance with the ACCOMPLISHMENT INSTRUCTIONS section of Nomad Alert Service Bulletin ANMD-57-13, dated October 30, 1995: (1) Remove any deposits between contacts; (2) Tighten any loose contacts; and (3) Replace any aft wing break connectors with arcing damage. (c) The repetitive inspections specified in this AD are required even if deposit is removed between the aft wing break connector contacts; any aft wing break connector contacts are tightened; or any aft wing break connectors are replaced. [[Page 62516]] (d) 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 airplane to a location where the requirements of this AD can be accomplished. (e) An alternative method of compliance or adjustment of the compliance time that provides an equivalent level of safety may be approved by the Manager, FAA, Los Angeles ACO, 3960 Paramount Boulevard, Lakewood, California 90712. The request shall be forwarded through an appropriate FAA Maintenance Inspector, who may add comments and then send it to the Manager, Los Angeles ACO. Note 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Los Angeles ACO. (f) The inspections, removal, tightening, and replacement required by this AD shall be done in accordance with Nomad Alert Service Bulletin ANMD-57-13, dated October 30, 1995. 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.
