Is AD 2009-18-10 a recurring Airworthiness Directive?

Yes — AD 2009-18-10 requires a repetitive inspection every 24 months. Next-due depends on the aircraft's time in service.

Airworthiness Directives; Boeing Model 707 Airplanes, and Model 720 and 720B Series Airplanes

What this AD requires

The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 707 airplanes, and Model 720 and 720B series airplanes. The existing AD currently requires repetitive detailed inspections to detect cracks and corrosion on any existing repairs and at certain body stations (STA) of the visible surfaces of the wing to body terminal fittings including the web, flanges, and ribs; and applicable related investigative and corrective actions. This new AD retains the requirements of the existing AD and requires repetitive ultrasonic inspections to detect any stress corrosion cracks within the outboard flange of the left and right body terminal fittings at STA 820, and related investigative and corrective actions if necessary. This AD also provides an optional terminating action for the repetitive inspections. This AD also adds two airplanes to the applicability. This AD results from reports of cracks found in the wing to body terminal fittings during routine inspections. We are issuing this AD to detect and correct cracks and corrosion in the body terminal fittings above and below the floor, which could cause loss of support for the wing and could adversely affect the structural integrity of the airplane.

Repetitive inspection. Re-inspect every 24 months. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Applicability limited to airplanes identified in Boeing 707 Alert Service Bulletin A3524, Revision 1, dated September 18, 2008.

Whether AD 2009-18-10 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.

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.
