Airworthiness Directive · Amendment 39-17235 · Hydraulic power
Airbus Airplanes
This AD applies to Airbus Model A330-201, -202, -203, -223, -243, -223F, -243F, -301, -302, -303, -321, -322, -323, -341, -342, and -343 airplanes; and Airbus Model A340-211, -212, -213, -311, -312, and -313 airplanes; certificated in any category; all manufacturer serial numbers.
We are adopting a new airworthiness directive (AD) for all Airbus Model A330-200 freighter series airplanes; Model A330-200 and - 300 series airplanes; and Model A340-200 and -300 series airplanes. This AD was prompted by reports of ram air turbine (RAT) pump failure. This AD requires inspecting the RAT pump anti-stall valve for correct setting, re-identifying the RAT pump, performing a functional ground test of the RAT, and replacing the RAT pump or the RAT assembly with a serviceable part if necessary. We are issuing this AD to detect and correct malfunction of the RAT pump, which could lead to in-flight loss of the RAT-pump pressurization, possibly resulting in reduced control 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.
(1) Within the applicable compliance time specified in table 1 to paragraph (g)(1) of this AD, as applicable, check the RAT pump anti-stall valve for correct setting, re-identify the RAT pump, and do a functional ground test of the RAT, except as provided by paragraph (g)(3) of this AD; in accordance with the Accomplishment Instructions of the applicable service bulletin specified in paragraph (g)(1)(i) or (g)(1)(ii) of this AD.
| Affected airplanes | Compliance time |
|---|---|
| For airplanes on which Airbus A330 certification maintenance requirements (CMR) Task 292000-00001-1-C, or Airbus A340-200/-300 CMR Task 292000-A0001-1-C, or Airbus A330/A340 maintenance review board report (MRBR) Task 29.20.00/06, as applicable to the airplane type, has not been accomplished as of the effective date of this AD. | Within 3,000 flight hours or 7 months, whichever occurs first after the effective date of this AD. |
| For airplanes on which the Airbus A330 CMR Task 292000-00001-1-C, or Airbus A340-200/-300 CMR Task 292000-A0001-1-C, or Airbus A330/A340 MRBR Task 29.20.00/06, as applicable to the airplane type, has already been accomplished as of the effective date of this AD. | Within 24 months after the last accomplishment of Airbus A330 CMR Task 292000-00001-1-C, or Airbus A340-200/-300 CMR Task 292000-A0001-1-C, or Airbus A330/A340 MRBR Task 29.20.00/06, applicable to the airplane type, or 30 days after the effective date of this AD, whichever occurs later. |
(i) Airbus Mandatory Service Bulletin A330-29-3117, dated July 19, 2011 (for Model A330 series airplanes).
(ii) Airbus Mandatory Service Bulletin A340-29-4090, dated July 19, 2011 (for Model A340 series airplanes).
(2) If the functional ground test of the RAT, as required by paragraph (g)(1) of this AD, is not successful (as defined by the Accomplishment Instructions of the applicable service bulletin specified in paragraph (g)(1)(i) or (g)(1)(ii) of this AD): Before further flight, replace the RAT pump or the RAT assembly with a serviceable part, in accordance with the Accomplishment Instructions of the applicable service bulletin specified in paragraph (g)(1)(i) or (g)(1)(ii) of this AD.
(3) Any airplane equipped with a RAT hydraulic pump marked with an “X” or a date (month/year) in the amendment cell C of the identification plate, which has been successfully tested (as defined by the Accomplishment Instructions of the applicable service bulletin specified in paragraph (g)(1)(i) or (g)(1)(ii) of this AD) in accordance with the Accomplishment Instructions of the applicable service bulletin specified in paragraph (g)(1)(i) or (g)(1)(ii) of this AD prior to the effective date of this AD, is considered compliant with the requirements of paragraphs (g)(1) and (g)(2) of this AD.
As of the effective date of this AD, no person may install any RAT hydraulic pump or RAT assembly on any airplane unless it has been inspected, corrected, and successfully tested (as defined by the Accomplishment Instructions of the applicable service bulletin specified in paragraph (g)(1)(i) or (g)(1)(ii) of this AD) in accordance with the requirements of paragraph (g) of this AD, on any airplane.
A serviceable part is a RAT hydraulic pump or RAT assembly that has been inspected, corrected, and successfully tested (as defined by the Accomplishment Instructions of the applicable service bulletin specified in paragraph (g)(1)(i) or (g)(1)(ii) of this AD), in accordance with the Accomplishment Instructions of the applicable service bulletin specified in paragraph (g)(1)(i) or (g)(1)(ii) of this AD.
