AD 2018-03-20 Airworthiness Directives; Airbus Airplanes
Models named: A330-301, -302, -303, -321, -322, -323, -341, -342, -343. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Airbus Model A330-301, -302, -303, -321, -322, -323, -341, -342, and -343 airplanes, certificated in any category, all manufacturer serial numbers on which Airbus modification 58244 or modification 58245 has been embodied in production, except those on which modification 202779 has been embodied in production.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Within 30 days after the effective date of this AD, request instructions from the Manager, International Section, Transport Standards Branch, FAA, to address the unsafe condition specified in paragraph (e) of this AD; and accomplish the actions at the times specified in, and in accordance with, those instructions. Guidance can be found in Mandatory Continuing Airworthiness Information (MCAI) European Aviation Safety Agency (EASA) AD 2013-0291, dated December 9, 2013.
Unsafe condition
This AD was prompted by a report indicating that a pipe of the fire extinguishing system in the forward cargo compartment was too long, and therefore could be installed only under stress, which applies pressure to the pipe clamp. We are issuing this AD to prevent this pipe clamp from breaking, allowing the pipe to come into contact with the structure, possibly resulting in leakage in the Halon piping. This condition could lead to functional loss of the fire extinguishing system, which, in combination with a fire, could lead to an uncontrolled fire in the lower deck cargo compartment, and possible loss 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.
