95-26-18 MAULE AEROSPACE TECHNOLOGY, INC.: Amendment 39-9476; Docket No. 95-CE-97-AD. Applicability: M-4, M-5, M-6, M-7, MX-7, MXT-7 Series and Models MT-7-235, and M-8-235 Airplanes (all serial numbers), certificated in any category that are equipped with part number (P/N) 2079E rear wing lift struts and P/N 2080E front wing lift struts. NOTE 1: This AD applies to each airplane identified in the preceding applicability revision, 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 (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 hasnot been eliminated, the request should include specific proposed actions to address it. Compliance: Required within the next 30 calendar days after the effective date of this AD, unless already accomplished. NOTE 2: The compliance times and inspection intervals indicated in this AD take precedence over the compliance times and inspection intervals called for in the Maule Service Bulletin (SB) No. 11, Issued: October 30, 1995.

To prevent corrosion of the wing lift strut, which, if not detected and corrected, could cause the wing to separate from the airplane, accomplish the following: (a) Inspect the two rear wing lift struts, (P/N 2079E) and the two front wing lift struts (P/N 2080E) for internal corrosion in accordance with the INSTRUCTIONS and INSPECTION PROCEDURE sections specified in Maule SB No. 11, Issued: October 30, 1995. (1) If evidence of corrosion damage is found, prior to further flight, accomplish one of the following: (i) Replace the damaged strut with an airworthy strut of the same part number that has been treated internally with corrosion preventative in accordance with the INSPECTION PROCEDURE section specified in Maule SB No. 11, Issued October 30, 1995, or (ii) Replace the damaged strut with a sealed wing lift strut, P/N 2200E or P/N 2201E, as applicable, in accordance with the instructions specified in PART II of the INSTRUCTIONS section of Maule SB No. 11, Issued October 30, 1995. (2) If no evidence of corrosion damage is found, prior to further flight, treat the strut internally with corrosion preventative in accordance with the NOTE in the INSPECTION PROCEDURE section in Maule SB No. 11, Issued October 30, 1995. (b) 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, Atlanta Aircraft Certification Office, Campus Building, 1701 Columbia Avenue, suite 2-160, College Park, Georgia 30337-2748. The request shall be forwarded through an appropriate FAA Maintenance Inspector, who may add comments and then send it to the Manager, Atlanta Aircraft Certification Office. NOTE 4: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Atlanta Aircraft Certification Office. (c) The inspection and possible replacements required by this AD shall be done in accordance with Maule Service Bulletin No. 11, Issued: 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.
