Remove the four screws that attach the flange to the cover.

Those units and components which furnish a means of supporting and steering the aircraft on the ground or water, and make it possible to retract and store the landing gear in flight. Includes brakes, wheels, floats, doors, shock struts, tires, linkages, position indicating and warning systems.

Flight Controls System refers to those units and components which furnish a means of manually controlling the flight attitude characteristics of the aircraft, including items such as hydraulic boost system, rudder pedals, control column linkages, control cables, tab controls, mounting brackets, etc.

Tank and reservoir capacities in U.S., imperial and metric measure, shall be included. ANA or other standard specification number and grade (if applicable) of fuel, oil, fluid, and other material used shall be given. Specifications and grades shall be shown grouped on one page to facilitate revisions. For fuel, given expansion volume, total fuel capacity, sump capacity, net fuel capacity (as applicable). For oil, given allowance for expansion.

Chapter 26 is entitled "Fire Protection", and is about those fixed and portable units and components which detect and indicate fire or smoke, and store and distribute fire extinguishing agent to all protected areas of the aircraft, including bottle, valves, tubing, etc., if furnished as manufacturer designated standard equipment.

Under the title "Emergency" in Chapter 25 are those items of equipment carried for use in emergency procedures. Includes items such as evacuation equipment, life rafts and jackets, first aid kit, landing and signal flares, evacuation signaling systems, etc., if furnished as manufacturer-designated standard equipment. Does not include fire extinguishers, oxygen equipment or masks.

The adjustment/test description shall provide instructions for accomplishment of a test or check to assure the integrity as an operational component of a system, subsystem or unit assembly. Such tests or checks will vary in complexity and stringency according to the conditions under which the unit functions. It is not intended that a complex functional test of a complete system and its attendant closer tolerances be performed if the unit replaced reactiviates the system and operates within the confines of a go-no-go specification .

Deactivation/Reactivation procedures for circuits, systems, units, etc., shall be included. This is important because during maintenance, certain components may need to be deactivated for safety reasons or to prevent damage to the aircraft or equipment. It is also important to have instructions for reactivating these components once maintenance is complete to ensure that they are functioning properly and do not pose a risk to the safety of the aircraft or its occupants.

The cooled air from the air cycle machine can no longer hold the quantity of water it could when it was warm. A water separator is used to remove the water from the saturated air before it is sent to the aircraft cabin. Foggy air from the ACM condenses and coalesces the mist into larger water drops in the water separator. The water collects on the sides of the separator and drains down and out of the unit, while the dry air passes through.

The yaw damper works by sensing any yaw motion and then applying corrective inputs to the aircraft＇s rudder to reduce or eliminate any unwanted yawing. It is particularly useful in minimizing the effects of turbulence or other external disturbances that can cause yawing and make the aircraft harder to control. The yaw damper is an important safety feature that helps to improve the overall stability and control of the aircraft, especially during critical phases of flight such as takeoff and landing.

Polyurethane is used for producing the fuselage, wing tips, and other curved parts of small aircraft; relatively inexpensive, fuel resistant, and compatible with most adhesives; do not use a hot wire to cut polyurethane foam; easily contoured with a large knife and sanding equipment.
