AD 97-28880 · 1997-11-03 · airframe

Airworthiness Directives; Fairchild Aircraft, Inc. SA226 and SA227 Series Airplanes

What this AD requires

This amendment supersedes Airworthiness Directive (AD) 93-15- 02 R2, which currently requires the following on Fairchild Aircraft, Inc. (Fairchild Aircraft) SA226 and SA227 series airplanes that are equipped with a certain Simmonds-Precision pitch trim actuator: repetitively measuring the freeplay of the pitch trim actuator and repetitively inspecting the actuator for rod slippage; immediately replacing any actuator if certain freeplay limitations are exceeded or rod slippage is evident; and, eventually replacing the actuator regardless of the inspection results. This action retains the repetitive inspections and replacement requirements, adds the repetitive inspections after the installation of certain Barber-Coleman pitch time actuators, and removes the terminating action. This action is the result of failure of the no-backs on a Barber-Colman pitch time actuator installed on a Fairchild Aircraft SA227 series airplane. The actions specified by this AD are intended to prevent failure of the pitch trim actuator, which could cause loss of control of the airplane.

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

Whether AD 97-28880 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 97-28880 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.
