Models named: V2522-A5, V2524-A5, V2525-D5, V2527-A5, V2527E-A5, V2527M-A5, V2528-D5, V2530-A5, V2531-E5, V2533-A5. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to International Aero Engines AG (IAE AG) Model V2522-A5, V2524-A5, V2525-D5, V2527-A5, V2527E-A5, V2527M-A5, V2528-D5, V2530-A5, V2531-E5, and V2533-A5 engines with a 3rd stage high-pressure compressor (HPC) rotor blade having part number (P/N) 6A8353 or P/N 6A8688 installed.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
At the next engine shop visit after the effective date of this AD where the 3rd stage HPC rotor blade is exposed, replace the full set of 3rd stage HPC rotor blades with parts eligible for installation.
Unsafe condition
This AD was prompted by multiple reports of failed 3rd stage HPC rotor blades that resulted in engine fires, unplanned engine removals, aborted takeoffs, and in-flight shutdowns (IFSD). The FAA is issuing this AD to prevent failure of the 3rd stage HPC rotor blades. The unsafe condition, if not addressed, could result in engine fire, reduced control of the airplane, and engine IFSD.
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.
