Airworthiness Directive · Amendment 39-10188 · Fairchild Aircraft, Inc. SA226 and SA227 Series Airplanes
Fairchild Aircraft, Inc. SA226 and SA227 Series Airplanes
Superseded. A later AD replaced this one: AD 2000-03-17. Comply with the one in force.
All SA226 and SA227 series airplanes (all models and serial numbers), certificated in any category, that are equipped with a Simmonds-Precision pitch trim actuator, (part number (P/N) DL5040M5 or P/N DL5040M6) or a Barber-Colman pitch trim actuator (P/ N 27-19008-001 or P/N 27-19008-002).
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.
