Is AD 97-31676 a recurring Airworthiness Directive?

No — AD 97-31676 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 97-31676 apply to?

AD 97-31676 applies to Raytheon — models 100, 200, 2000, 300, 58, 60, 90. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Raytheon Aircraft Company 58, 60, 90, 100, 200, and 300 Series and Model 2000 Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD) that applies to all Raytheon Aircraft Company (Raytheon) 58, 60, 90, 100, 200, and 300 series and Model 2000 airplanes (formerly referred to as Beech 58, 60, 90, 100, 200, and 300 series and Beech Model 2000 airplanes). This AD requires replacing certain AlliedSignal Aerospace outflow/safety valves in the pressurization system with new or serviceable valves. The AD results from a report of cracking and consequent failure of the affected outflow safety valves in the pressurization system. Investigation has revealed problems during the manufacturing process of certain AlliedSignal outflow/safety valves. The actions specified by this AD are intended to prevent outflow/safety valve cracking and consequent failure, which could result in rapid decompression of the airplane.

Whether AD 97-31676 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 97-31676 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.
