Is AD 99-10-06 a recurring Airworthiness Directive?

Yes — AD 99-10-06 requires a repetitive inspection every 50 hours. Next-due depends on the aircraft's time in service.

Which aircraft does AD 99-10-06 apply to?

AD 99-10-06 applies to Raytheon. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Raytheon Aircraft Corporation Model Beech 2000 Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Corporation (Raytheon) Model Beech 2000 airplanes. This AD requires immediately incorporating temporary revisions to the Limitations Section of the Airplane Flight Manual (AFM) that include requirements of not allowing flap operation during takeoff, accomplishing the preflight visual checks (referred to as visual inspections in the AFM temporary revisions) of the aft cove panel of the wing for delamination prior to each flight, and incorporating a repair scheme if delamination is found. This AD also requires repetitively inspecting the trailing edge of the wing by looking for delamination (debonding) (also referred to as cracks in the service information) through the thickness of the trailing edge of the wing cove skin panels, and modifying the center flap track rib attachment when delamination (debonding) is found. This AD is the result of a report of the wing cove skin panel separating from the wing while in flight on one of the affected airplanes. The actions specified by this AD are intended to detect and correct delamination of the wing cove skin in the area of the support rib, which could result in the delamination propagating to the trailing edge of the wing with the wing cove skin panel possibly separating from the wing.

Repetitive inspection. Re-inspect every 50 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

MakesRaytheon

Boilerplate applicability only; the specific model/serial-number list precedes this excerpt and is not included. Requires incorporating AFM temporary revisions restricting flap operation on takeoff and adding preflight visual checks, plus repetitive inspections of the wing trailing-edge cove skin for delamination/debonding per Raytheon Safety Communique No. 158 (March 1999), with repair per Raytheon Field Repair drawing FR-SS-00010 if found, to prevent the wing cove skin panel from separating from the wing.

Whether AD 99-10-06 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.

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.
