2009-16-02 Pilatus Aircraft Limited: Amendment 39-15985; Docket No. FAA-2009-0509; Directorate Identifier 2009-CE-029-AD. Effective Date (a) This airworthiness directive (AD) becomes effective September 9, 2009. Affected ADs (b) None. Applicability (c) This AD applies to Model PC-7 airplanes, all manufacturer serial numbers, certificated in any category. Subject (d) Air Transport Association of America (ATA) Code 53: Fuselage. Reason (e) The mandatory continuing airworthiness information (MCAI) states: This Airworthiness Directive (AD) is prompted due to reported corrosion on the bolts and in the bores of the attachment fittings for the engine mounting frame. The corrosion is caused by damaged cadmium plating of the bolts or damaged surface finish of the attachment fitting. Such a condition, if left uncorrected, could lead to crack initiation at the bolt and the fitting bore and subsequently to the failure of the engine attachment fitting. In order to correct and control the situation, this AD requires a visual inspection of the relevant bolts and fittings. Additionally, the replacement of the bolts is required. Actions and Compliance (f) Unless already done, do the following actions: (1) Visually inspect the bolts and the bores (with boroscope) of the attachment fittings for the engine mounting frame following paragraph 3.A of PILATUS Aircraft Ltd. Pilatus PC-7 Service Bulletin No. 53-006, dated November 17, 2008, at whichever of the following occurs later: (i) Upon accumulating 5,000 hours total time-in-service (TIS) or 5 years from the date of manufacture, whichever occurs first; or (ii) Within the next 6 months after September 9, 2009 (the effective date of this AD). (2) If no sign of corrosion is found during the inspection required in paragraph (f)(1) of this AD, before further flight, replace the bolts. Repetitively inspect thereafter at intervals not to exceed every 5years following PILATUS Aircraft Ltd. Pilatus PC-7 Maintenance Manual Chapter 05-10-20, page 4, dated November 30, 2008. (3) If any sign of corrosion is found during any of the inspections required in paragraphs (f)(1) and (f)(2) of this AD, before further flight, do the corrective actions following paragraph 3.A. of PILATUS Aircraft Ltd. Pilatus PC-7 Service Bulletin No. 53- 006, dated November 17, 2008. Repetitively inspect thereafter at intervals not to exceed every 5 years following PILATUS Aircraft Ltd. Pilatus PC-7 Maintenance Manual Chapter 05-10-20, page 4, dated November 30, 2008. FAA AD Differences Note: This AD differs from the MCAI and/or service information as follows: No differences.
