2011-06-01: Flight Controls

0 2. The FAA amends Sec. 39.13 by adding the following new AD: 2011-06-01 APEX Aircraft: Amendment 39-16625; Docket No. FAA-2010- 1296; Directorate Identifier 2010-CE-063-AD. Effective Date (a) This airworthiness directive (AD) becomes effective April 13, 2011. Affected ADs (b) None. Applicability (c) This AD applies to APEX Aircraft Model CAP10 B and CAP10 B airplanes with Major Change 000302 (commercial name CAP10C), all serial numbers, certificated in any category. Subject (d) Air Transport Association of America (ATA) Code 27: Flight Controls. Reason (e) The mandatory continuing airworthiness information (MCAI) states: A fatal accident occurred to a CAP 10C, in which the pilot lost control of the aeroplane. The following investigation has revealed that the probable cause of the accident was the improper locking of a turnbuckle (locking clip missing) of the flight control cables, and the subsequent inadvertent release of the pitchup control cable from the turnbuckle. For the above described reasons, this AD requires repetitive inspections to verify the correct installation of the turnbuckles of the flight control cables and, if foreseen by the applicable design configuration of the turnbuckles and found to be missing, to restore the locking clip and the safety wire. Actions and Compliance (f) Unless already done, do the following actions: (1) Within the next 2 months after April 13, 2011 (the effective date of this AD): (i) If the turnbuckles are designed to be locked with locking clips and safety wire, verify that the locking clips are properly installed in the corresponding groove, that the safety wire of a minimum diameter of 0.8 millimeter (mm) is correctly installed, and that there is no damage to the whole turnbuckle installation. (ii) For all other designs of turnbuckles, verify the correct installation of the safety locking devices. (iii) If any discrepancy is found during the inspection required by paragraph (f)(1)(i) or (f)(1)(ii) of this AD, before further flight, restore the correct turnbuckle installation in accordance with standard maintenance practice. (2) Repeat the inspection required by paragraph (f)(1)(i) or (f)(1)(ii) of this AD, as [[Page 12847]] applicable to the turnbuckles design, and the associated corrective actions required by paragraph (f)(1)(iii) of this AD at intervals not to exceed 110 hours time-in-service or 13 months since the last inspection, whichever occurs first. FAA AD Differences Note: This AD differs from the MCAI and/or service information as follows: No differences. Other FAA AD Provisions (g) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Sarjapur Nagarajan, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4145; fax: (816) 329-4090. Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO. (2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service. (3) Reporting Requirements: For any reporting requirement in this AD, a Federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to a penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB Control Number. The OMB Control Number for this information collection is 2120-0056. Public reporting for this collection of information is estimated to be approximately 5 minutes per response, including the time for reviewing instructions, completing and reviewing the collection of information. All responses to this collection of information are mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at: 800 Independence Ave., SW., Washington, DC 20591, Attn: Information Collection Clearance Officer, AES-200.
