Applicability*9
This AD applies to the Airbus airplanes, certificated in any category, identified in paragraphs (c)(1) through (c)(4) of this AD, all manufacturer serial numbers. (1) Airbus Model A318-111 and -112 airplanes. (2) Airbus Model A319-111, -112, -113, -114, and -115 airplanes. (3) Airbus Model A320-211, -212, and -214 airplanes. (4) Airbus Model A321-111, -112, -211, -212, and -213 airplanes.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
At the applicable compliance time specified in paragraph (h) of this AD: Do a high frequency eddy current (HFEC) inspection for cracking and corrosion of each T/R pivot fitting specified in paragraphs (g)(1) and (g)(2) of this AD, and do all applicable corrective actions, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-70-1003, Revision 01, dated December 28, 2015; and Goodrich Aerostructures Service Bulletin RA32078-137, Rev. 3, dated March 14, 2016; as applicable; except as required by paragraph (i) of this AD. Do all applicable corrective actions before further flight. Repeat the inspection of the T/R pivot fittings thereafter at intervals not to exceed 60 months or 12,000 flight cycles, whichever occurs first. (1) The 3 o'clock position T/R pivot fittings having part numbers (P/N) that are provided in paragraphs (g)(1)(i) through (g)(1)(iv) of this AD. (i) P/N 321-200-850-6. (ii) P/N 321-200-851-6. (iii) P/N 321-200-852-6. (iv) P/N 321-200-853-6. (2) The 9 o'clock position T/R pivot fittings having P/Ns that are provided in paragraphs (g)(2)(i) through (g)(2)(iv) of this AD. (i) P/N 321-200-800-6. (ii) P/N 321-200-801-6. (iii) P/N 321-200-802-6. (iv) P/N 321-200-803-6.
Unsafe condition
This AD was prompted by reports of cracks on the 3 o'clock and 9 o'clock pivot fittings of a CFM56 engine's thrust reverser (T/R). We are issuing this AD to detect and correct such cracking and corrosion, which could lead to T/R malfunction and, in a case of rejected takeoff at V 1 on a wet runway, a consequent runway excursion, possibly resulting in damage to the airplane and injury to occupants.
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.
