AD 2014-22-05 Airworthiness Directives; The Boeing Company Airplanes
Models named: DC-9-11, DC-9-12, DC-9-13, DC-9-14, DC-9-15, DC-9-15F, DC-9-21, DC-9-41, DC-9-51. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to The Boeing Company Model DC-9-11, DC-9-12, DC-9-13, DC-9-14, DC-9-15, and DC-9-15F airplanes; Model DC-9-21 airplanes; Model DC-9-31, DC-9-32, DC-9-32 (VC-9C), DC-9-32F, DC-9-33F, DC-9-34, DC-9-34F, and DC-9-32F (C-9A, C-9B) airplanes; Model DC-9-41 airplanes; and Model DC-9-51 airplanes; certificated in any category; equipped with a ventral aft pressure bulkhead.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
(1) For the purposes of this AD, the term “original tee section” refers to the original (non-peened) ventral aft pressure bulkhead web to fuselage skin attach tee sections. (2) For the purposes of this AD, the term “improved tee section” refers to improved (shot peened) ventral aft pressure bulkhead web to fuselage skin attach tee sections.
Unsafe condition
This AD was prompted by an evaluation by the design approval holder (DAH) indicating that the improved (shot-peened) ventral aft pressure bulkhead dome tees, which connect the bulkhead web to the fuselage, are subject to widespread fatigue damage (WFD). We are issuing this AD to detect and correct fatigue cracking of the improved (shot-peened) ventral aft pressure bulkhead dome tees connecting the bulkhead web to the fuselage, which could result in reduced structural integrity and rapid decompression of the airplane.
Affected ADs
This AD affects certain requirements of AD 96-16-04, Amendment 39-9704 (61 FR 39860, July 31, 1996).

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.
