Airworthiness Directives; Raytheon Aircraft Company Model 1900D Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Company (Raytheon) Model 1900D airplanes. This action requires modifying the airplane by incorporating Raytheon Kit No. 129-5200-1, ``Ground Fine Switch Installation Kit''. This action is the result of design analysis during certification of 5.5 degree approach landings of the Model 1900D airplanes. The actions specified by this AD are intended to prevent a loose or misrigged ground fine switch, which could result in very hard landings causing structural damage to the airplane and possible passenger injury.

Whether AD 98-16166 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 98-16166 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.
