AD 2024-01-06 Airworthiness Directives; The Boeing Company Airplanes
Models named: 737-600, 737-700, 737-800 series. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to The Boeing Company Model 737-600, 737-700, and 737-800 series airplanes, certificated in any category, as identified in Boeing Alert Service Bulletin 737-53A1217, Revision 1, dated September 8, 2022.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Except as specified in paragraph (h) of this AD: For Group 1 through 3, Configuration 3 airplanes as identified in Boeing Alert Service Bulletin 737-53A1217, Revision 1, dated September 8, 2022, at the applicable times specified in Tables 3 through 6 of paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin 737-53A1217, Revision 1, dated September 8, 2022, do all applicable actions identified as “RC” (required for compliance) in, and in accordance with, the Accomplishment Instructions of Boeing Alert Service Bulletin 737-53A1217, Revision 1, dated September 8, 2022.
Unsafe condition
This AD was prompted by an evaluation by the design approval holder (DAH) indicating the fuselage skin repairs at the double row of fasteners centered on certain stringers have inadequate inspection requirements for continuing airworthiness following repair accomplishment, which could result in fatigue cracking of the repair going undetected. The FAA is issuing this AD to address the inadequacy of post-repair inspection requirements at certain repair fastener locations centered on stringer S-17L and S-17R, at station (STA) 360 to STA 380 and at STA 888 to STA 907. Such inspection inadequacy could result in post-repair fatigue cracks going undetected. Fatigue cracking, if not addressed, could grow to a critical length, which could result in rapid decompression and loss of structural integrity 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.
