Is AD 2016-19-04 a recurring Airworthiness Directive?

Yes — AD 2016-19-04 requires a repetitive inspection every 1000 hours. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2016-19-04 apply to?

AD 2016-19-04 applies to Boeing — models -8, 787. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; The Boeing Company Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This AD was prompted by a report of uncommanded movement by a captain's seat during a landing rollout due to a failure in the seat horizontal actuator. This AD requires repetitive tests of the captain and first officer seat assemblies for proper operation, and corrective action if necessary. This AD also requires installation of new captain and first officer seat assemblies, which terminates the repetitive tests. We are issuing this AD to prevent a seat actuator clutch failure, which could result in a loss of seat locking and uncommanded motion of the captain's or first officer's seat; uncommanded seat movement could result in reduced controllability of the airplane.

Repetitive inspection. Re-inspect every 1000 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

MakesBoeing

Models-8, 787

Applies only to airplanes identified in Boeing Alert Service Bulletin B787-81205-SB250054-00, Issue 001, dated December 19, 2014.

Whether AD 2016-19-04 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 2016-19-04 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.
