Airworthiness Directive · Amendment 39-15864 · Flight controls
ATR Model ATR72 Airplanes
This AD applies to ATR Model ATR72-101, -102, -201, -202, -211, -212, and -212A airplanes, all serial numbers, certificated in any category; as identified in paragraphs (c)(1) and (c)(2) of this AD, as applicable.
(1) This AD applies to airplanes on which Avions de Transport Regional Service Bulletin ATR72-27-1059 was done in service at original issue, dated October 3, 2006; or Revision 01, dated March 14, 2007; except as provided by paragraph (c)(2) of this AD.
(2) This AD does not apply to airplanes on which Avions de Transport Regional Service Bulletin ATR72-27-1059, Revision 02, dated May 19, 2008; or Revision 03, dated October 3, 2008; was done in service, or ATR Modification 05572 was done in production. Modification 05572 is factory-incorporated on ATR72-212A airplanes from manufacturer's serial number (MSN) 730.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, do the following actions.
(1) Within 10 days after the effective date of this AD: Verify installation of the four cotter pins securing the nuts of the fastener assemblies connecting the elevator control rods to the elevator bellcranks as shown in Figure 1 of the Accomplishment Instructions of Avions de Transport Regional Service Bulletin ATR72-27-1059, Revision 02, dated May 19, 2008; or Revision 03, dated October 3, 2008.
(2) If any cotter pin is found missing, before further flight, install a new cotter pin with part number MS24665-164 by doing all the applicable actions in accordance with the Accomplishment Instructions of Avions de Transport Regional Service Bulletin ATR72-27-1059, Revision 02, dated May 19, 2008; or Revision 03, dated October 3, 2008.
Note 1: For accessing the zone to be inspected, panels 325BL, 325BR, 327HL, 327KL, 327KR, 327JR, 327JL, 333BB, and 334BB may need to be removed. Information pertaining to removal procedures can be found in the Accomplishment Instructions of Avions de Transport Regional Service Bulletin ATR72-27-1059, Revision 02, dated May 19, 2008; or Revision 03, dated October 3, 2008.
(3) Before further flight after accomplishment of paragraph (f)(2) of this AD, perform an operational test of the elevator control as specified in paragraph 3.D., “Tests,” of the Accomplishment Instructions of Avions de Transport Regional Service Bulletin ATR72-27-1059, Revision 02, dated May 19, 2008; or Revision 03, dated October 3, 2008. If any elevator control rod fails the operational test, before further flight, repair using a method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the European Aviation Safety Agency (EASA) (or its delegated agent).
Note 2: This AD differs from the MCAI and/or service information as follows: The MCAI does not specify corrective action for failure of the operational test (binding or friction) specified in paragraph (f)(3) of this AD. This AD requires using a method approved by the Manager, International Branch, ANM-116; or the EASA (or its delegated agent) and performing corrective action before further flight.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
