Airplane Assembly

Aileron Installation

  • Most manufacturer’s maintenance and illustrated parts book must be followed to ensure the correct procedures and hardware is being used for the installation of the control surfaces
  • All of the control surfaces require specific hardware, spacers, and bearings are installed to ensure the surface does not jam or become damaged during movement.
  •  After the aileron is connected to the flight deck controls, the control system must be inspected to ensure the cables/push-pull rods are routed properly.  
  • When the balanced cable is installed, check for correct attachment and operation to determine the ailerons are moving in the proper direction and opposite each other.

Flap Installation

  • The design, installation, and systems that operate flaps are as varied as the models of airplanes on which they are installed. 
  • As with any system on a specific aircraft, the manufacturer’s maintenance manual and the illustrated parts book must be followed to ensure the correct procedures and parts are used.
  •  Simple flap systems are usually operated manually by cables and/or torque tubes. Typically, many of the smaller manufactured airplane designs have flaps that are actuated by torque tubes and chains through a gearbox driven by an electric motor.

Empennage Installation

  • The empennage, consisting of the horizontal and vertical stabilizer is not normally removed and installed unless the aircraft was damaged. Elevators, rudders, and stabilators are rigged the same as any other control surface, using the instructions provided in the manufacturer’s maintenance manuals.
