Airbus Model A330-243, -341, -342, and -343 Airplanes Equipped with Rolls-Royce RB211 TRENT 700 Engines
Superseded. A later AD replaced this one: AD 2012-19-02. Comply with the one in force.
This AD applies to Airbus Model A330-243, -341, -342, and -343 airplanes, certificated in any category; equipped with Rolls-Royce RB211 TRENT 700 engines.
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A330-243, -341, -342, and -343 airplanes equipped with Rolls-Royce RB211 TRENT 700 engines. This AD requires modifying the cowl assemblies of the left- and right-hand thrust reversers. This AD results from a review of certification tests of the thrust reverser, which revealed that certain structural components within the C-duct need strengthening to meet high fatigue loads and maintain structural integrity. We are issuing this AD to prevent fatigue cracking of the hinges integrated into the 12 o'clock beam of the thrust reversers, which could result in separation of a thrust reverser from the airplane, and consequent reduced controllability of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
At the applicable compliance time specified in Table 1 of this AD: Modify the cowl assemblies of the left- and right-hand thrust reversers in accordance with Airbus Service Bulletin A330-78-3010, Revision 03, dated April 28, 2004.
| Replace part number— | At the later of the times specified— | |
| (1) 3410L, 3410R, 3411L, 3411R, 3412R, 3413R | (i) Before the accumulation of 10,000 total flight cycles since the C-duct was new | (ii) Within 6 months after the effective date of this AD. |
| (2) 3414L, 3416R, 3417R | (i) For airplanes modified according to Airbus Service Bulletin A330-78-3010 with more than 7,200 total flight cycles since the C-duct was new: Before the accumulation of 10,000 total flight cycles since the C-duct was new | (iii) Within 6 months after the effective date of this AD. |
| (ii) For airplanes modified according to Airbus Service Bulletin A330-78-3010 with less than or equal to 7,200 total flight cycles since the C-duct was new: Before the accumulation of 25,000 total flight cycles since the C-duct was new | ||
| (3) 3414L, 3416R, 3417R | (i) For airplanes modified in production by Airbus Modification 47316: Before the accumulation of 25,000 total flight cycles since the C-duct was new | (ii) Within 6 months after the effective date of this AD. |
| (4) 3412L, 3414R | (i) For airplanes modified in production by Airbus Modification 46879: Before the accumulation of 25,000 total flight cycles since the C-duct was new | (ii) Within 6 months after the effective date of this AD. |
| (5) 3413L, 3415R | (i) Before the accumulation of 40,000 total flight cycles since the C-duct was new | (ii) Within 6 months after the effective date of this AD. |
Note 1: Airbus Service Bulletin A330-78-3010, Revision 03, dated April 28, 2004, refers to Rolls-Royce Service Bulletin RB.211-78-C899, Revision 3, dated May 7, 2004, as an additional source of service information for modifying the cowl assemblies of the left- and right-hand thrust reversers.
As of the effective date of this AD, no person may install, on any airplane, a cowl assembly of the left- or right-hand thrust reverser if the airplane has exceeded the applicable flight cycle threshold specified in Table 1 of this AD.
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.
