What this AD requires

We are revising Airworthiness Directive (AD) 2018-03-03 for certain Textron Aviation Inc. Models 401, 401A, 401B, 402, 402A, 402B, 402C, 411, 411A, 414, 414A, 421, 421A, 421B, 421C, and 425 airplanes. AD 2018-03-03 required repetitively inspecting the left and the right forward lower carry through spar cap for cracks and replacing the carry through spar cap if cracks were found. This AD addresses the same unsafe condition and requires the same actions as AD 2018-03-03, but clarifies the compliance times for the initial inspection of the carry through spar cap. This AD was prompted by several reports of confusion in interpreting the compliance times for the initial inspection of the carry through spar cap. We are issuing this AD to eliminate confusion in interpreting the compliance times for this inspection.

Repetitive inspection. Re-inspect every 50 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

The applicable model list is presented as an embedded graphic/table ("[GRAPHIC] [TIFF OMITTED] TR08MY18.009") in the source text and was not OCR-captured; specific models could not be enumerated from the available applicability text.

Whether AD 2018-03-03 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 2018-03-03 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.
