Airworthiness Directives; Raytheon Model BAe.125 Series 1000A and 1000B, and Model Hawker 1000 Series Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD), applicable to all Raytheon Model BAe.125 series 1000A and 1000B, and Model Hawker 1000 series airplanes, that requires inspection of P1 pitot pipes for chafing or damage, and various follow-on actions. This amendment is prompted by reports of P1 pitot pipes chafing against adjacent flight control cables. The actions specified by this AD are intended to prevent a hole in the P1 pitot pipes, which would lead to erroneous input to the instrumentation and warning systems associated with the pilot's instruments.

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

Whether AD 99-30947 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 99-30947 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.
