Airworthiness Directive 97-12516

AD 97-12516 · 1997-05-15 · airframe

Airworthiness Directives; Raytheon Aircraft Company Model 1900D Airplanes (formerly Beech Aircraft Corporation)

What this AD requires

This amendment adopts a new airworthiness directive (AD) that applies to Raytheon Aircraft Company (Raytheon) Model 1900D airplanes (formerly referred to as Beech Aircraft Corporation Model 1900D). This action requires inspecting the stabilon attachment angles for the correct thickness, repetitively inspecting for cracks, and replacing the attachment angles that are the incorrect thickness with ones of the correct thickness. Recent reports of the affected airplanes having the incorrect size stabilon attachment angles prompted this action. The actions specified by this AD are intended to prevent separation of the stabilon from the airplane, which could cause loss of airplane stability during flight.

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.

Which aircraft AD 97-12516 applies to

MakesRaytheon Aircraft Company

Stabilon (ventral fin) attachment angle thickness inspection per Beechcraft MSB No. 2651 (Issued Jan 1996); angles measuring only .071in get repetitive 50-hr TIS crack inspections until replaced with .090in angles (or replaced outright within 600 hrs TIS if no cracks appear), which terminates the requirement. The specific affected model designation is not present in the extracted applicability window.

Whether AD 97-12516 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 97-12516 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.
