Is AD 96-21375 a recurring Airworthiness Directive?

Yes — AD 96-21375 requires a repetitive inspection. Next-due depends on the aircraft's time in service.

Which aircraft does AD 96-21375 apply to?

AD 96-21375 applies to Jetstream — models 3201. Serial/part conditions may narrow it to specific aircraft.

What this AD requires

This amendment supersedes Airworthiness Directive (AD) 87-07- 01, which currently requires the following on Jetstream Aircraft Limited (JAL) HP137 Mk1, Jetstream series 200, and Jetstream Model 3101 airplanes: repetitively inspecting the nose landing gear (NLG) top cap assembly securing bolts for looseness or cracks, retorquing any loose security bolt, and replacing any cracked security bolt. AD 87-07-01 also provides the option of incorporating an NLG modification as terminating action for the repetitive inspections. A report of cracked and loose bolts found on an airplane with the above-referenced NLG modification prompted this action. This action: retains the repetitive inspections required by AD 87-07-01; increases the AD applicability to include Jetstream Model 3201 airplanes and airplanes that have the NLG top cap assembly modified in accordance with AD 87-07-01; requires replacing two of the NLG top cap assembly securing bolts; and incorporates a new NLG top cap assembly that would eliminate the repetitive inspection requirement of the AD. The actions specified in this AD are intended to prevent failure of the NLG caused by cracked or loose securing bolts, which, if not detected and corrected, could lead to NLG collapse and damage to the airplane.

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

incorporating

Whether AD 96-21375 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.
