Airworthiness Directives; Kaman Aerospace Corporation Model K-1200 Helicopters

What this AD requires

This amendment adopts a new airworthiness directive (AD) for Kaman Aerospace Corporation (Kaman) Model K-1200 helicopters. This action requires certain initial and repetitive visual inspections of the main rotor blade (blade) grips for a crack. If a crack is found, this AD requires replacing the blade grip before further flight. This amendment is prompted by an accident involving the loss of all blades because of a crack in a blade grip on the upper surface around the bolthole. The actions specified in this AD are intended to prevent failure of a blade grip, loss of a blade, and subsequent loss of control of the helicopter.

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.

Whether AD 2004-13-26 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.
