Is AD 06-403 a recurring Airworthiness Directive?

No — AD 06-403 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 06-403 apply to?

AD 06-403 applies to Raytheon — models 1000, 1000A, 800B. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Raytheon Model DH.125, HS.125, and BH.125 Series Airplanes; Model BAe.125 Series 800A (C-29A and U-125), 800B, 1000A, and 1000B Airplanes; and Model Hawker 800 (including variant U-125A), and 1000 Airplanes

What this AD requires

The FAA is superseding an existing airworthiness directive (AD), which applies to certain Raytheon airplanes identified above. That AD currently requires a visual inspection to determine whether adequate clearance exists between the fan venturi motor casing and the adjacent equipment, and adjustments, if necessary; and a visual inspection to detect signs of overheating, degradation of insulating materials, and ingestion of debris into the motor, and replacement of discrepant parts with serviceable parts. This new AD instead requires that operators replace the fan venturi with a new or modified part. This AD results from reports that the fan venturi overheated and produced smoke while the airplane was on the ground. We are issuing this AD to prevent heat and fire damage to equipment adjacent to the fan venturi, which could result in smoke in the cabin and/or burning equipment.

Whether AD 06-403 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 06-403 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.
