Airworthiness Directive 2000-13-06
recurringAirworthiness Directives; Sikorsky Model S-61 Helicopters
What this AD requires
This amendment supersedes an existing airworthiness directive (AD) for Sikorsky Model S-61 helicopters. That AD requires inspecting certain pylon upper and lower hinge web fittings (web fittings) for corrosion or a crack and either repairing certain web fittings or replacing any unairworthy web fittings with airworthy web fittings. That AD also requires creating a log card or equivalent record and implementing a recurring inspection of the web fittings. This amendment retains the requirements of that AD but corrects an error in paragraph (a)(3) by removing the words "and 3.E." This amendment is prompted by an operator notifying the FAA of that error which requires an unnecessary major inspection within 25 hours time-in-service (TIS). The actions specified in this AD are intended to remove an undue burden on the public by superseding the AD and removing the requirement for the major inspection within 25 hours TIS.
Which aircraft AD 2000-13-06 applies to
Pylon upper hinge web fitting (P/N S6120-76261-012/-013) and lower hinge web fitting (P/N S6120-76262-012/-013) alloy-temper determination, inspection, and repair/replacement, per Sikorsky Alert Service Bulletin No. 61B20-33. Specific helicopter model not explicitly named in the excerpted text.
Whether AD 2000-13-06 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:
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.
