The primary function of the hydraulic pressure system is to supply pressure for the operation of the flight controls.

A. The airworthiness problem needs to be resolved by the way any other airplane does in the operator＇s fleet has equal or more damaging corrosion, and it has to be done before the regular check of that zone.

B. The airworthiness problem needs immediate action ahead of the next planning inspection of that zone, because it would probably occur on another plane in the operator＇s fleet, causing equivalent or more serious corrosion.

C. Due to any other airplane in the operator＇s fleet could have the comparable or more vital corrosion, the airworthiness problem should be investigated immediately before the next periodic inspection of that zone.

A. Detection and coding systems shall be used so that it＇s easy to isolate faults, repair routes and replace the components.

B. You should use the detecting and coding system that can help to remove faults, repair lines and change the components.

C. To facilitate troubleshooting, repair of circuits, and replacement of components, an identification and coding system should be used.

A. Accumulate the thickness of the shim as follows: t=x-y.

B. Calculate the thickness of the shim as follows: t=x-y.

C. Calculate the width of the shim as follows: t=x-y.

A. However, manufacturers may omit System/Chapters that are not applicable to the product or combine Systems/Chapters where it is feasible.

B. However, manufacturers may adopt Systems/Chapters that are not applicable to the product or constitute Systems/Chapters when necessary.

C. However, operators may omit Systems/Chapters applicable to the product or constitute Systems/Chapters where practical.
