Airworthiness Directives; PZL Swidnik S.A. Helicopters

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain PZL Swidnik S.A. (PZL) Model W-3A helicopters. This AD requires repetitive inspections of the main transmission (Main XSMN) case for a crack, and depending on the inspection outcome, removing the WR-3 Main XSMN from service before further flight. This AD was prompted by a report of cracks in a Main XSMN case. The actions of this AD are intended to address an unsafe condition on these products.

Repetitive inspection. Re-inspect every 25 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Which aircraft AD 2020-15-06 applies to

MakesPzl Swidnik
ModelsW-3A, W-3
Serial-conditional — narrows to serials ?–3X.10.12.
Part-conditional — 64.21.0105, 64.22.0161, 64.21.3000, 64.21.4000.

Applies only to helicopters with serial number up to and including 3X.10.12, with a main transmission (Main XMSN) case P/N 64.21.0105 or 64.22.0161, installed on a WR-3 Main XMSN P/N 64.21.3000 or 64.21.4000.

Whether AD 2020-15-06 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 2020-15-06 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.
