Is AD 98-34385 a recurring Airworthiness Directive?

Yes — AD 98-34385 requires a repetitive inspection. Next-due depends on the aircraft's time in service.

Which aircraft does AD 98-34385 apply to?

AD 98-34385 applies to Raytheon — models 1900, 1900C, 1900D. Serial/part conditions may narrow it to specific aircraft.

What this AD requires

This amendment supersedes Airworthiness Directive (AD) 97-14- 16, which applies to Raytheon Aircraft Company (Raytheon) Models 1900, 1900C, and 1900D airplanes. AD 97-14-16 currently requires repetitively inspecting the outboard flap support roller bearings and flap attachment brackets for indications of contact (wear), inspecting for elongated holes in the flap attachment brackets, repairing or replacing any part showing wear, and replacing any bracket with elongated holes. AD 97-14-16 was the result of five incidents where the flap roller bearings rubbed on the flap attachment brackets and resulted in aileron interference. This AD retains the repetitive inspection requirement of AD 97-14-16, but reduces the number of ground-air-ground (GAG) cycles allowed between inspections and lowers the total number of accumulated GAG cycles allowed before mandatory accomplishment of the initial inspection. This AD also provides the option of replacing the outboard flap roller bearings with parts of improved design as terminating action for the repetitive inspection requirement. The actions specified by this AD are intended to prevent asymmetric flaps, jammed flaps, and/ or possible interference between the flap and the aileron, which could inhibit aileron travel and result in possible loss of roll 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.

applicability derived from the AD summary — confirm the model/serial from the records

Whether AD 98-34385 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.

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.
