AD 2014-23-07 Airworthiness Directives; Airbus Airplanes
Models named: A330-201, -202, -203, -223, -243, -301, -302, -303, -321, -322. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Airbus Model A330-201, -202, -203, -223, -243, -301, -302, -303, -321, -322, -323, -341, -342, and -343 airplanes; and Model A340-211, -212, -213, -311, -312, and -313 airplanes; certificated in any category; all manufacturer serial numbers, except for those airplanes that have had Airbus Modification 52980 incorporated in production on both main landing gear (MLG) units, or airplanes that have had Airbus Modification 54500 incorporated in production.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
At the applicable time specified in paragraph (g)(1) or (g)(2) of this AD: Do a detailed inspection for cracking of the visible chromed area of the MLG retraction actuator piston rods in the fully extended position, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A330-32-3173, Revision 05, dated September 26, 2008 (for Model A330-200 and -300 series airplanes); or Airbus Service Bulletin A340-32-4212, Revision 05, dated September 26, 2008 (for Model A340-200 and -300 series airplanes). Repeat the inspection thereafter at intervals not to exceed 8 days until the actions required by paragraphs (j) and (o) of this AD are accomplished. (1) For MLG retraction actuator piston rods that have not had a detailed inspection accomplished as of the effective date of this AD, as described in any applicable service information specified in paragraph (h)(1) or (h)(2) of this AD: At the applicable time specified in paragraph (g)(1)(i) or (g)(1)(ii) of this AD. (i) For MLG retraction actuator piston rods having part number (P/N) 114256309 or P/N 114256321 issue 03: Do the inspection within 60 days after the effective date of this AD, or before the MLG retraction actuator has been in service 36 months, whichever occurs later. (ii) For MLG retraction actuator piston rods having P/N 114256326 issue 01 or P/N 114256321 issue 06: Do the inspection within 60 days after the effective date of this AD, or before the MLG retraction actuator has been in service 72 months, whichever occurs later. (2) For MLG retraction actuator piston rods having P/N 114256309, P/N 114256321 issue 03, P/N 114256326 issue 01, or P/N 114256321 issue 06, that have had a detailed inspection accomplished as of the effective date of this AD, as described in the applicable service information specified in paragraph (h)(1) or (h)(2) of this AD: Inspect within 8 days after the effective date of this AD.
Unsafe condition
This AD was prompted by reports of the piston rods for the MLG retraction actuators rupturing during flight. We are issuing this AD to prevent cracking of the piston rods for the MLG retraction actuators, which could result in rupture of a piston rod, non-damped extension of the MLG, high loads on the fully extended MLG, and consequent reduced structural integrity of the MLG.
Affected ADs
This AD replaces AD 2004-16-01, Amendment 39-13757 (69 FR 46979, August 4, 2004).

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.
