Airworthiness Directives; Raytheon Aircraft Company Model 1900, 1900C, 1900C (C-12J), and 1900D Airplanes

What this AD requires

The FAA adopts a new airworthiness directive (AD) for certain Raytheon Aircraft Company (Raytheon) Model 1900, 1900C, 1900C (C-12J), and 1900D airplanes that do not have canted bulkhead Kit No. 129-4005-1 S incorporated. This AD requires you to repetitively inspect the canted bulkhead located at Fuselage Station (FS) 588.10 for cracks and incorporate canted bulkhead Repair Kit No. 129-4005-1 S anytime cracks are found. When Kit No. 129-4005-1 S is incorporated, the repetitive inspection requirement in this AD is terminated and no further action is required. This AD is the result of numerous reports of multi-site cracks occurring in the canted bulkhead at FS 588.10. We are issuing this AD to detect and correct cracks in the canted bulkhead. These cracks could result in failure of the bulkhead. Failure of the canted bulkhead could lead to loss of rudder and elevator control, which could result in loss of control of the airplane.

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 04-9898 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 04-9898 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.
