Airworthiness Directive 2003-13-15
recurringAirworthiness Directives; Schweizer Aircraft Corporation Model 269A, 269A-1, 269B, 269C, and TH-55A Helicopters
What this AD requires
This amendment supersedes an existing airworthiness directive (AD), applicable to Schweizer Aircraft Corporation (Schweizer) Model 269A, 269A-1, 269B, 269C, and TH-55A 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 by the existing AD. This amendment requires the same actions as the existing AD, and also requires 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. This amendment is prompted by the need to expand the applicability to include certain Hughes-manufactured cluster fittings and to provide a terminating action for the repetitive dye-penetrant inspections of the cluster fittings. 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
Applies to Schweizer Model 269 helicopters (269C named explicitly in the text) to prevent failure of a tailboom support strut or a cluster-fitting lug. Helicopters with cluster fitting P/N 269A2234 or 269A2235: dye-penetrant inspect lugs every 50 hrs TIS (10-hr initial), replace cracked fittings before further flight; fittings not modified with Kit P/N SA-269K-106-1 are not eligible replacements; within 150 hrs TIS/6 months replace or modify with the kit (terminating action for the repetitive inspection). Helicopters with strut assembly P/N 269A2015 or 269A2015-5: inspect aluminum end fittings every 50 hrs TIS; if damaged, modify with stainless steel end fittings P/N 269A2017-3/-5 or replace with P/N 269A2015-9/-11; full modification/replacement required within 500 hrs TIS or 1 year.

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.
