Is AD 2009-23-01 a recurring Airworthiness Directive?

Yes — AD 2009-23-01 requires a repetitive inspection. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2009-23-01 apply to?

AD 2009-23-01 applies to Hawker Beechcraft Corporation — models 1900, 1900C, 1900D. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Hawker Beechcraft Corporation Model 1900, 1900C, and 1900D Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Models 1900, 1900C, and 1900D airplanes. This AD requires a one-time visual inspection and repetitive ultrasonic inspections of the left and right main landing gear (MLG) actuators for leaking and/or cracks with replacement of the actuator if leaking and/ or cracks are found. This AD results from reports of leaking and cracked actuators. We are issuing this AD to detect and correct leaking and cracks in the MLG actuators, which could result in loss of hydraulic fluid. This condition could lead to an inability to extend or lock down the landing gear, which could result in a gear up landing or a gear collapse on landing.

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.

Serial-conditional — narrows to serials UA-3–UA-3, UB-1–UB-74, UC-1–UC-174, UD-1–UD-6, UE-1–UE-439.

Part-conditional — 114-380041-11, 114-380041-13, 114-380041-15, 114-380041-15OVH, 1FA10043-3.

Applies only to airplanes equipped with a Hawker Beechcraft main landing gear (MLG) actuator P/N 114-380041-11, 114-380041-13, 114-380041-15, or 114-380041-15OVH (or FAA-approved equivalent P/N, including Frisby Airborne Hydraulic, Inc. P/N 1FA10043-3, which has parts manufacturer approval by identicality to P/N 114-380041-15). Serial ranges are per model: 1900 UA-3; 1900C UB-1 through UB-74 and UC-1 through UC-174, and UD-1 through UD-6; 1900D UE-1 through UE-439.

Whether AD 2009-23-01 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 2009-23-01 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.
