Airworthiness Directive · Amendment 39-19757 · Engine exhaust
Airbus SAS Airplanes
This AD applies to all Airbus SAS Model A330-243, A330-243F, A330-341, A330-342, and A330-343 airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A330-243, A330-243F, A330-341, A330-342, and A330-343 airplanes. This AD was prompted by reports of thrust reverser unit (TRU) beams found with evidence of thermally caused material degradation in the rearmost section of the TRU beam at certain latches. This AD requires an inspection for heat damage of each left-hand and right-hand TRU beam as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. Depending on findings, this AD might also require inspections of the TRU beam latches, the TRU beam clevises, and the thrust reverser outer fixed structure rear area; corrective actions; and replacement of TRU beams. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2018-0148R1, dated April 5, 2019 (“EASA AD 2018-0148R1”).
(1) Where EASA AD 2018-0148R1 refers to its effective date, or July 27, 2018 (the effective date of EASA AD 2018-0148, dated July 13, 2018), this AD requires using the effective date of this AD.
(2) The “Remarks” section of EASA AD 2018-0148R1 does not apply to this AD.
(3) Where the service information referenced in EASA AD 2018-0148R1 specifies the installation of AN960 washers, this AD allows the installation of NAS1149 series washers.
(4) Where the service information referenced in EASA AD 2018-0148R1 specifies the installation of NAS6303U04 bolts, this AD allows the installation of NAS6303U4 bolts.
(5) Where the service information referenced in EASA AD 2018-0148R1 specifies the use of NAS5050-4C nuts, this AD allows the use of NSA5050-4C nuts.
(6) Where the service information referenced in EASA AD 2018-0148R1 refers to “Rolls Royce SRM 54-02-04” for paint restoration, for this AD replace the phrase “Rolls Royce SRM 54-02-04” with “Airbus SRM 51-75.”
(7) Where the service information referenced in EASA AD 2018-0148R1 refers to “CMM 78-30-20 Figure 38 Graphic 78-30-20-991-838-A01” for replacement of damaged right-hand thrust reverser latch covers and hardware, for this AD replace the phrase “CMM 78-30-20 Figure 38 Graphic 78-30-20-991-838-A01” with “CMM 78-30-20 Figure 39 Graphic 78-30-20-991-839-A01.”
(8) Where the service information referenced in EASA AD 2018-0148R1 specifies to de-energize the ground service network, as specified in aircraft maintenance manual (AMM) 24-42-00, before closing the fan cowl doors, this AD allows de-energizing the ground service network after closing the fan cowl doors.
Although the service information referenced in EASA AD 2018-0148R1 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
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.
