Is AD 2009-26-04 a recurring Airworthiness Directive?

Yes — AD 2009-26-04 requires a repetitive inspection every 24 months. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2009-26-04 apply to?

AD 2009-26-04 applies to Boeing — models 737-600, 737-700, 737-700C, 737-800, 737-900, 737. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Boeing Model 737-600, -700, -700C, -800, and -900 Series Airplanes

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 737-600, -700, -700C, -800, and -900 series airplanes. This AD requires repetitive lubrication of the left and right main landing gear (MLG) forward trunnion pins; and an inspection for discrepancies of the transition radius, lead-in chamfer, and cross- bolt bore of the MLG forward trunnion pins, and repair or replacement if necessary. Doing the applicable inspections and repairs/ replacements, or overhauling the trunnion pins ends the repetitive lubrication requirements of this AD. For airplanes on which a certain repair is done, this AD requires repetitive inspections for discrepancies of the transition radius. This AD results from a report that the protective finishes on the forward trunnion pins for the left and right MLG might have been damaged during final assembly. We are issuing this AD to prevent cracking of the forward trunnion pin, which could result in fracture of the pin and consequent collapse of the MLG.

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.

Models737-600, 737-700, 737-700C, 737-800, 737-900, 737

Applies only to airplanes identified in Boeing Service Bulletin 737-32-1376, Revision 2, dated August 6, 2008.

Whether AD 2009-26-04 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.

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.
