Is AD 03-20710 a recurring Airworthiness Directive?

No — AD 03-20710 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 03-20710 apply to?

AD 03-20710 applies to Boeing — models 757. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Boeing Model 757-200 and -200PF Series Airplanes Equipped With Pratt and Whitney PW2000 Series Engines

What this AD requires

This amendment revises an existing airworthiness directive (AD), applicable to certain Boeing Model 757-200 and -200PF series airplanes, that currently requires inspections, adjustments, and functional checks of the engine thrust reverser system; and modification of the engine thrust reverser directional control valve. The existing AD also requires installation of an additional thrust reverser locking feature and periodic functional tests of the locking feature following installation. That AD was prompted by results of a safety review of the thrust reverser system on these airplanes. The actions specified by that AD are intended to prevent deployment of a thrust reverser in flight and subsequent reduced controllability of the airplane. This action reduces the applicability of the existing AD.

Applicability provision truncated in this excerpt ('each airplane identified in the preceding applicability provision'); text covers thrust reverser directional control valve (DCV) inspection/replacement and control-system functional tests, with differing procedures for airplanes with line numbers prior to vs. at/after 442; restates AD 91-20-09.

Whether AD 03-20710 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 03-20710 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.
