What this AD requires

We are superseding Airworthiness Directive (AD) 2016-09-05, which applied to certain The Boeing Company Model 717-200 airplanes. AD 2016-09-05 required a detailed inspection for distress of the vertical stabilizer leading edge skin, and related investigative and corrective actions if necessary. It also required, for certain airplanes, repetitive inspections of the front spar cap for any loose or missing fasteners, or any cracking, and related investigative and corrective actions if necessary. This AD requires repetitive inspections for distress, cracking, and loose or missing fasteners in the vertical stabilizer leading edge skin and front spar cap, with new compliance times for certain airplanes. This AD was prompted by reports of cracking in the leading edge of the vertical stabilizer and front spar web. 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.

Models717-200, 717

Applies to airplanes identified in Boeing Alert Service Bulletin 717-55A0012, Revision 1, dated April 11, 2018.

Whether AD 2018-10-08 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 2018-10-08 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.
