Airworthiness Directive 2023-21632

one-time
AD 2023-21632 · 2023-10-02 · airframe

Airworthiness Directives; British Aerospace (Operations) Limited and British Aerospace Regional Aircraft Airplanes

What this AD requires

The FAA is superseding Airworthiness Directive (AD) 2017-19-22 for all British Aerospace Regional Aircraft Jetstream Series 3101 and Jetstream Model 3201 airplanes. AD 2017-19-22 required incorporating BAE Systems' Corrosion Prevention and Control program into the Airworthiness Limitations Section (ALS) of the existing instructions for continued airworthiness (ICA) for your airplane, which added new and more restrictive inspections for corrosion that include inspecting the door hinges/supporting structure and attachment bolts for the main spar joint and engine support, and the rudder hinge location on the vertical stabilizer, and applicable corrective actions. Since the FAA issued AD 2017-19-22, the Civil Aviation Authority (CAA) of the United Kingdom (UK) superseded the mandatory continuing airworthiness information (MCAI) issued by the European Aviation Safety Agency (now European Union Aviation Safety Agency) (EASA) to correct an unsafe condition on these products. This AD requires revising the ALS of the existing ICA for your airplane. The FAA is issuing this AD to address the unsafe condition on these products.

Applies to all serial numbers. Jetstream 3101 per British Aerospace (Operations) Limited; Jetstream 3201 per British Aerospace Regional Aircraft.

Whether AD 2023-21632 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

Supersession

Supersedes AD 2017-19-22.

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 2023-21632 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.
