Airworthiness Directives; Boeing Model 727 Airplanes

What this AD requires

The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 727 series airplanes. That AD currently requires repetitive inspections to detect cracks and loose brackets of the elevator rear spar, and corrective actions if necessary. The existing AD also provides for an optional terminating action for the repetitive inspections. This new AD reduces the repetitive intervals of the inspections, mandates the previously optional terminating action for the repetitive inspections, and no longer allows stop-drilling. This AD results from new reports of cracks, elongated fastener holes, and loose fittings of the elevator rear spar. We are issuing this AD to prevent cracking of the elevator rear spar at the tab hinge locations, which could cause excessive freeplay of the elevator control tab and possible tab flutter, and consequent loss of control of the airplane.

Repetitive inspection. Re-inspect every 4000 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

MakesBoeing
Models727, 727C, 727-100, 727-100C, 727-200, 727-200F

Applies to airplanes as identified in Boeing Service Bulletin 727-55-0089, Revision 1, dated March 2, 2000.

Whether AD 2008-17-14 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 2008-17-14 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.
