Airworthiness Directives; The Boeing Company Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD was prompted by a report of cracks in a certain body station (STA) frame web and doubler at fastener holes common to the stop fitting at a certain stringer. This AD requires repetitive surface high frequency eddy current (HFEC) inspections for cracking of the frame web and doubler at the stop fitting at a certain stringer, and applicable on-condition actions. We are issuing this AD to address the unsafe condition on these products.

Repetitive inspection. Re-inspect. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Applies regardless of STC ST01219SE installation; no separate change-in-product AMOC request is required for airplanes with STC ST01219SE installed. Required actions further scoped by Group 1 vs. Groups 2-5 per Boeing Requirements Bulletin 737-53A1375 RB, dated March 12, 2018.

Whether AD 2019-01-06 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.
Date — When the work was done.
Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.
Signature & certificate — The A&P/IA who returned it to service, with certificate number.
Is AD 2019-01-06 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
