Airworthiness Directive 2003-13-15
one-timeAirworthiness Directives; Schweizer Aircraft Corporation Model 269A, 269A-1, 269B, 269C, and TH-55A Helicopters
What this AD requires
This amendment revises an existing airworthiness directive (AD), for the specified Schweizer Aircraft Corporation (Schweizer) model helicopters, that currently requires inspecting the lugs on certain aft cluster fittings and each aluminum end fitting on certain tailboom struts. Modifying or replacing each strut assembly within a specified time period and serializing certain strut assemblies are also required. Additionally, a one-time inspection and repair, if necessary, of certain additional cluster fittings, and replacement and modification of certain cluster fittings within 150 hours time-in- service (TIS) or 6 months, whichever occurs first, is required. This amendment requires the same actions as the existing AD, but revises the Applicability section of the AD. This amendment is prompted by the discovery of an error in the Applicability section of the existing AD. The actions specified by this AD are intended to prevent failure of a tailboom support strut or a cluster fitting, which could cause rotation of a tailboom into the main rotor blades, and subsequent loss of control of the helicopter.
Which aircraft AD 2003-13-15 applies to
Extracted applicability text is corrupted (contains Federal Register preamble/summary text rather than a clean applicability paragraph). Confirmed reference is to Schweizer Aircraft Corporation Model 269C helicopters, addressing tailboom support strut and cluster fitting part numbers 269A2234/269A2235 and 269A2015/-5/-11 (modification kit SA-269K-106-1) and cluster fittings 269A2234-3/269A2235-3. Full applicability scope could not be reliably determined from this text.
Whether AD 2003-13-15 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.
