2010-22-09 Pilatus Aircraft Ltd.: Amendment 39-16488; Docket No. FAA-2010-0849; Directorate Identifier 2010-CE-043-AD. Effective Date (a) This airworthiness directive (AD) becomes effective December 3, 2010. Affected ADs (b) None. Applicability (c) This AD applies to PILATUS Aircraft Ltd. Model PC-7 airplanes, manufacturer serial numbers (MSN) 101 through 618, certificated in any category. Subject (d) Air Transport Association of America (ATA) Code 57: Wings. Reason (e) The mandatory continuing airworthiness information (MCAI) states: This Airworthiness Directive (AD) is prompted due to an occurrence when an aircraft had a partial in-flight separation of the aileron outboard bearing support. The aileron outboard bearing supports are attached with two forward attachment bolts and two aft attachment bolts. The forward attachment bolts are approximately 3.2 mm (0.125 inch) longer than the aft attachment bolts. If the aileron outboardbearing supports have been removed, it is possible that during the reinstallation of the aileron outboard bearing supports, the attachment bolts can be installed in wrong positions. Bolts that are installed in wrong positions can damage the threads in the rear attachment anchor nuts. Such a condition, if left uncorrected, could lead to in-flight separation of the aileron outboard bearing support, and as a consequence, the loss or limited controllability of the aircraft. In order to correct and control the situation, this AD requires a one time inspection to verify that the bolts are installed in the correct positions and the threads of the anchor nuts are in good condition. The replacement of the attachment hardware is required if any damage on the anchor nut threads or a bolt at the wrong location is found. Actions and Compliance (f) Unless already done, do the following actions: (1) Within 1 month after December 3, 2010 (the effective date of this AD), check the airplane maintenance records to determine if the left and/or right aileron outboard bearing supports have been removed at any time during the life of the airplane. Do this check following paragraph 3.A. of Pilatus Aircraft Ltd. PC-7 Service Bulletin No. 57-015, Rev. No. 1, dated July 23, 2010. (2) If an entry is found during the airplane maintenance records check required in paragraph (f)(1) of this AD or it is unclear whether or not the left and/or right aileron outboard bearing supports have been removed at any time during the life of the airplane, before further flight, do the actions specified in paragraphs 3.A.(2) through paragraph 3.E of Pilatus Aircraft Ltd. PC-7 Service Bulletin No. 57-015, Rev. No. 1, dated July 23, 2010. FAA AD Differences Note: This AD differs from the MCAI and/or service information as follows: No differences.
