Airworthiness Directive · Amendment 39-16399 · Powerplant
Airbus Model A330-223, -321, -322, and -323 Airplanes
This AD applies to Airbus Model A330-223, -321, -322, and -323 airplanes; certificated in any category; all manufacturer serial numbers.
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:
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Do a detailed inspection to determine the part number, serial number, and lot number of the forward and aft mount pylon bolts on both engines, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A330-71-3020, dated June 10, 2009. Inspect at the later of the times specified in paragraphs (g)(1) and (g)(2) of this AD.
(1) Before the accumulation of 8,000 total flight cycles or 24,000 total flight hours since first flight of the airplane, whichever occurs first.
(2) Within 24 months after the effective date of this AD.
(h) If the identified part number, serial number, or lot number corresponds to suspect bolts identified in Pratt & Whitney Service Bulletin PW4G-100-71-35, Revision 1, dated December 4, 2009, before further flight remove the affected bolt and replace with a serviceable bolt, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A330-71-3020, dated June 10, 2009. Identifying part numbers, serial numbers or lot numbers before the effective date of this AD according to Pratt & Whitney Service Bulletin PW4G-100-71-35, dated March 14, 2008, is considered acceptable for compliance with the corresponding action specified in this AD.
(i) If the bolt part number, serial number, or lot number is unreadable, before further flight, remove the affected bolt and replace with a serviceable bolt, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A330-71-3020, dated June 10, 2009.
(j) As of the effective date of this AD, no person may install any forward or aft mount pylon bolt on any airplane, unless this bolt has been identified as a non-suspect bolt, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A330-71-3020, dated June 10, 2009.
(k) Although Airbus Mandatory Service Bulletin A330-71-3020, dated June 10, 2009, specifies to submit certain information to the manufacturer, this AD does not include that requirement.
Note 1: This AD differs from the MCAI and/or service information as follows: Although the MCAI or service information tells you to submit information to the manufacturer, paragraph (k) of this AD specifies that such submittal is not required.
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.
