These actuators control the movement of the ailerons and elevators, which control the flight path of the airplane.

The Check List may be arranged by "Challenge" and "Response" headings for two pilot airplanes or by "Item" and "Condition" headings for single pilot airplanes. Under either method, the item to be checked is listed with the desired condition stated.

Airspeeds used in this Section shall be specified in Indicated Airspeed, assuming zero instrument error, in order to make the information as directly usable as possible.

Fig.1 in pages 11 and 12 are typical plating/skin illustrations as specified in System Chapters 53,54, 55 and 57.

A separate shading pattern to distinguish between supply, pressure, return, etc, shall be used. The same coding for each individual system shall be used throughout the manual.

Any revisions to a Maintenance Manual made necessary due to modifications of an airplane after delivery are the responsibility of the holder of the type design approval of the modification.

This specification was developed by representatives of member companies of the General Aviation Manufacturers Association for use in preparing Manufacturers Maintenance Data, in manual form, that will serve as a guide for the maintenance of airplanes in a continuous airworthy condition.

The pressure transducer is installed downstream of the shut-off valve.

Micro-switches in the actuator de-energize it at the end of travel.

A DC motor, which has a permanent high-speed magnet, supplies power to the actuator.

It operates when the pressure applied in the opposite direction is more than a set value.
