AD 2014-03-21 Airworthiness Directives; the Boeing Company Airplanes
Models named: 727-200, 727-200F series. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to The Boeing Company Model 727-200 and 727-200F series airplanes, certificated in any category, line numbers 1103 and subsequent.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Before the accumulation of 60,000 total flight cycles, or within 24 months after the effective date of this AD, whichever occurs later: Do a one-time detailed inspection for cracking of the pressure floor of both main wheel wells, in accordance with the Accomplishment Instructions of Boeing Service Bulletin 727-53A0124, Revision 3, dated November 30, 1989, except as specified in paragraph (h) of this AD. If any indication of distress is found (such as cracking or flaked paint): Before further flight, do an eddy current inspection or penetrant inspection for cracking of the pressure floor of both main wheel wells, and do all applicable related investigative and corrective actions, by accomplishing all the actions specified in the Accomplishment Instructions of Boeing Service Bulletin 727-53A0124, Revision 3, dated November 30, 1989. Do all applicable related investigative and corrective actions before further flight.
Unsafe condition
This AD is intended to complete certain mandated programs intended to support the airplane reaching its limit of validity (LOV) of the engineering data that support the established structural maintenance program. We are issuing this AD to prevent fatigue cracking in the pressure floor of the main wheel wells, which could lead to rapid loss of cabin pressurization.
Affected ADs
This AD affects AD 91-22-08, Amendment 39-8068 (56 FR 57233, November 8, 1991).

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.
