TRAILING EDGE FLAPS -OUTBOARD FLAP INBOARD TRANSMISSION ASSEMBLY

Purpose

The outboard flap inboard transmission assembly receives power from the torque tubes to move the outboard flap.
Location

The outboard flap inboard transmission assembly is just outboard of the engines. Access to the assembly is through
the fixed and moveable flap support fairings. 
Physical Description 
The transmission assembly is similar inboard transmission assembly, interchangeable.  to but  the inboard they are  flap not 
The transmission assembly weighs about 80  lb (36 kg). 
Functional Description 

The outboard flap inboard transmission assembly operation is similar to the assemblies for the inboard flap.
Training Information Point

The transmission contains oil and it is necessary to do servicing. Use the oil fill plug.
Before you remove the transmission assembly, remove the flap skew sensors to prevent damage to them.
When manually operating the flap drive system, observe this caution:
CAUTION:  DO NOT LET THE BALLSCREW NUTS HIT THE UPSTOPS OR THE DOWNSTOPS. YOU CAN CAUSE DAMAGE TO THE SHEAROUT IN THE POSITION SENSOR GEARBOX.

TRAILING EDGE FLAPS -OUTBOARD FLAP OUTBOARD TRANSMISSION ASSEMBLY

Purpose

The outboard flap outboard transmission assembly gets power from the torque tubes to move the outboard flap.
Location

The outboard flap outboard transmission assembly is near the outboard end of the outboard flap. Access to the assembly is
through the fixed and moveable flap support fairings. 
Physical Description 
The transmission assembly is similar inboard transmission assembly, interchangeable.  to but  the they inb are oard  flap not 

The transmission assembly weighs approximately 65 lb (30 kg).
Functional Description

The outboard flap outboard transmission assembly operation is similar to the assemblies for the inboard flap.
Training Information Point

The transmission contains oil and it is necessary to do servicing at specified times. Use the oil fill plug.
Before removing the transmission assembly, remove the flap skew sensors to prevent damage to them.
When manually operating the flap drive system, observe this caution:
CAUTION:  DO NOT LET THE BALLSCREW NUTS HIT THE UPSTOPS OR THE DOWNSTOPS. YOU CAN CAUSE DAMAGE TO THE SHEAROUT IN THE POSITION SENSOR GEARBOX.

TRAILING EDGE FLAPS -OUTBOARD FLAP SUPPORT MECHANISMS

Purpose

The flap transmission, ballscrew, and gimbal use the flap support mechanism to extend and retract the outboard flap.
Location

The outboard flap support mechanisms are near the ends of the outboard flap. To get access to the assemblies, remove the fixed and moveable flap support fairings.
Functional Description

During extension, the gimbal turns the drive arm about the fixed point. The drive arm moves the flap carrier to extend the outboard flap. The pivot link controls the rotation of the flap.
Retraction is the opposite of extension.
Training Information Point

When manually operating the flap drive system, observe this caution:
CAUTION:  DO NOT LET THE BALLSCREW NUTS HIT THE UPSTOPS OR THE DOWNSTOPS. YOU CAN CAUSE DAMAGE TO THE SHEAROUT IN THE POSITION SENSOR GEARBOX.

TRAILING EDGE FLAPS -OUTBOARD FLAP AUXILIARY SUPPORTS

Purpose

The outboard flap auxiliary supports make sure that the outboard flap deflection is similar to the wing deflection. When the flaps are extended, the outboard flap auxiliary supports prevent the ends of the flap from deflecting above the wing. When the flaps are retracted, the outboard flap auxiliary supports keep the flaps aligned with the wing.
