Required actions
For Airbus Model A330-200 freighter series airplanes, Model A330-200 and -300 series airplanes, and Model A340-200 and -300 series airplanes: Within 15,000 flight hours or 36 months, whichever occurs first after the effective date of this AD, identify the supplier, part number (P/N), and serial number (S/N) of the installed RAT actuator, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A330-29-3114, dated May 18, 2011 (for Model A330-200 freighter series airplanes, and Model A330-200 and -300 series airplanes); or Airbus Mandatory Service Bulletin A340-29-4089, dated May 18, 2011 (for Model A340-200 and -300 series airplanes). (1) If the supplier identified is Arkwin, and the identified actuator part number and serial number are listed as already modified in Hamilton Sundstrand Service Bulletin ERPS06M-29-18, dated March 8, 2011, but not yet re-identified: Before further flight, re-identify the actuator and the RAT, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A330-29-3114, dated May 18, 2011 (for Model A330-200 freighter series airplanes, and Model A330-200 and -300 series airplanes); or Airbus Mandatory Service Bulletin A340-29-4089, dated May 18, 2011 (for Model A340-200 and -300 series airplanes). (2) If the supplier identified is Arkwin Industries and the identified actuator part number and serial number are listed as not modified as specified in Hamilton Sundstrand Service Bulletin ERPS06M-29-18, dated March 8, 2011: Before further flight, replace the RAT actuator with a serviceable unit, and re-identify the RAT, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A330-29-3114, dated May 18, 2011 (for Model A330-200 freighter series airplanes, and Model A330-200 and -300 series airplanes); or Airbus Mandatory Service Bulletin A340-29-4089, dated May 18, 2011 (for Model A340-200 and -300 series airplanes).
Unsafe condition
This AD was prompted by reports of the ram air turbine (RAT) not deploying when tested. We are issuing this AD to prevent non-deployment of the RAT, which if occurred following a total engine flame-out, or during a total loss of normal electrical power generation, could result in reduced control of the airplane.
Affected ADs
None.

You just looked this one up by hand
TrackAD holds all 12,278 of them and matches them against the aircraft you actually look after — airframe, engine, propeller and appliances in one pass — then works out what falls due and when.
- Bring your existing list in from a spreadsheet Paste the rows straight out of Excel. Headers like C/W Date and N/A are read for you.
- A copy that works when this does not One file. No internet, no login, no this software running. For the morning something has to be produced and the computer is not cooperating.
- $5 a month, or $50 a year Up to 50 aircraft on either.
