Unsafe Condition (d) This AD results from several reports of failures of the actuator nut assembly, P/N GMD115-810029-17 and P/N GMD115-810029- 23, on the right MLG actuator. The actions specified in this AD are intended to prevent failure of the actuator nut assembly for the right MLG actuator, which could result in failure of the MLG. This failure could prevent the extension or retraction of the MLG. Compliance (e) To address this problem, you must do the following: Actions Compliance Procedures(1) Maintenance Records Check: (i) Check the maintenance records to determine whether the following replacements have been made: (A) Actuator nut assembly, P/N GMD115 810029 17, for the right MLG actuator; or (B) Actuator nut assembly, P/N GMD115 810029 23, for the right MLG actuator. (ii) The owner/operator holding at least a private pilot certificate as authorized by section 43.7 of the Federal Aviation Regulations (14 CFR 43.7) may make this check. You must make an entry into the aircraft records that shows compliance with this portion of the AD in accordance with section 43.9 of the Federal Aviation Regulations (14 CFR 43.9). Within the next 50 hours time-in-service (TIS) or 30 calendar days after July 28, 2006 (the effective date of this AD), whichever occurs first, unless already done. No special procedures necessary to check the maintenance records. (2) If you find as a result of the check required by paragraph (e)(1) of this AD that there is no record of the specified assembly replacement, inspect the airplane for installation of the following: (i) Actuator nut assembly, P/N GMD115 810029 17, for the right MLG actuator; or (ii) Actuator nut assembly, P/N GMD115 810029 23, for the right MLG actuator. (iii) You may choose to do the inspection without doing the maintenance records check. Within the next 50 hours TIS or 30 calendar days after July 28, 2006 (the effective date of this AD), whichever occurs first, unless already done. Follow General Machine Diecron, Inc. Service Bulletin GM D 32 30 01/102505, dated November 21, 2005. (3) If during the check required by paragraph (e)(1) or the inspection required by paragraph (e)(2) of this AD, you find either actuator nut assembly, P/N GMD115 810029 17 or P/N GMD115 810029 23, for the right MLG actuator, replace the specific assembly, with a new actuator nut assembly, P/N GMD115 810029 23B or FAA-approved equivalent P/N. Before further flight after the check required by paragraph (e)(1) or the inspection required by paragraph (e)(2) of this AD. Follow General Machine Diecron, Inc. Service Bulletin GM D 32 30 01/102505, dated November 21, 2005. (4) Do not install any actuator nut assembly, P/N GMD115 810029 17 or P/N GMD115 810029 23, for the right MLG actuator.
