Airworthiness Directive · Amendment 39-17197 · Engine exhaust
Airbus Airplanes
This AD applies to all Airbus Model A330-243, -243F, -341, -342 and -343 airplanes, certificated in any category.
We are superseding an existing airworthiness directive (AD) for all Airbus Model A330-243, -341, -342 and -343 airplanes. That AD currently requires modifying certain cowl assemblies of the left- and right-hand thrust reversers. This new AD requires removing certain C- duct assemblies of the left- and right-hand thrust reversers from service at certain designated life limits, and also adds airplanes to the applicability. This AD was prompted by new life limits on certain thrust reverser C-duct assemblies. 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 to paragraph (g) of this AD: Remove the applicable C-duct assemblies of the left- and right-hand thrust reversers, in accordance with a method approved by either the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the European Aviation Safety Agency (EASA) (or its delegated agent). Thereafter, for any C-duct assembly of the left- and right-hand thrust reversers installed after the effective date of this AD, before the accumulation of the applicable total flight cycles specified in table 1 to paragraph (g) of this AD: Remove the C-duct assembly, in accordance with a method approved by either the Manager, International Branch, ANM-116; or the EASA (or its delegated agent).

| HDTR3414L, HDTR3416R, HDTR3417R that have been modified in production by Airbus Modification 47316 or that have been modified in service as specified in Airbus Mandatory Service Bulletin A330-78-3010 or Rolls-Royce Service Bulletin RB.211-78-C899, before the accumulation of 7,200 total flight cycles since first installation on an airplane | Before the accumulation of 25,000 total flight cycles since the first installation of C-duct on the airplane | Within 3 months after the effective date of this AD. |
| HDTR3412L, HDTR3416L, HDTR3417L, HDTR3414R, HDTR3419R, HDTR3420R | Before the accumulation of 25,000 total flight cycles since the first installation of C-duct on the airplane | Within 3 months after the effective date of this AD. |
| HDTR3413L, HDTR3415R, HDTR3415L, HDTR3418R | Before the accumulation of 40,000 total flight cycles since the C-duct was new | Within 3 months after the effective date of this AD. |
