OUTBOARD FLAP - DESCRIPTION AND OPERATION
** ON A/C NOT FOR ALL
1. General
One outboard flap is installed on each of the right and the left wings.
In the retracted position, the outboard flap is the wing trailing edge between the inboard flap and the aileron.
The outboard flap is a fowler flap assembly with a tab on its trailing edge. One outboard flap is installed on each of the right and the left wings. In the retracted position,the outboard flap is the wing trailing edge between the inboard flap and the aileron.

2. Component Description
The outboard flap is the usual type of semi monocoque structure. It has spars and ribs made of Carbon-Fibre-Reinforced Plastics (CFRP). Only the elements that support are made of aluminum. The skin and the leading edge are made of Carbon-Fibre-Reinforced Plastics (CFRP). The trailing edge is made of aluminum. The nose of the tab is also made of aluminum. The trailing edge of the tab is made of honeycomb core with a skin made of aluminum sheet metal.
The carriage track 3 fitting attaches the flap to the carriage assy-track 3. The fitting has an eccentric spherical bearing.
The carriage track 4 fitting attaches the flap to the carriage assy-track 4. The fitting has an eccentric spherical bearing.
The outboard flap is the usual type of semi-monocoque structure. It has spars and ribs. The skin is made of Carbon-Fiber-Reinforced Plastics (CFRP). The leading edge has a CFRP monolithic structure. The trailing edge is made of honeycomb core with a skin of aluminum sheet metal.
The carriage track 3 fitting attaches the flap to the carriage assy-track 3 at RIB6 of the outboard flap. The fitting has an eccentric spherical bearing.
The carriage track 3 fitting is a fail-safe part.
The self-aligning support attaches the outer end of the outboard flap to the carriage assy-track 4. The support has an eccentric spherical bearing. The self-aligning support is a fail-safe part.
The fitting for track 3 is at RIB6, the fitting for track 4 is at RIB15. Each fitting holds an actuating linkage. A forked bolt assembly on each actuating linkage attaches the drive strut assembly to the flap rotary actuator.
The outboard flap has adjustable seal assemblies at the two ends.
The fitting for track 3 is at RIB6. The fitting for track 4 is at RIB15. The forked bolt assembly in each actuating linkage attaches the drive strut assembly to the flap rotary actuator.
The tab of the outboard flap is operated by a linkage system. It is linked at the carriages of track 3 and track 4. Drive struts operate the tab.
At RIB2, RIB9 and RIB12 are tab hinge stations installed. The stations have brackets and rods which support the tab during the extension of the flap. Fairings cover the tab hinge stations.
Three hoisting fittings are given to lift the outboard flap. The outboard flap has adjustable seal assemblies at the two ends to close the gap to the inboard flap and the aileron.
At the inboard end of the flap there is an interconnection strut. It connects the inboard and the outboard flaps. In case of a drive station failure, the interconnection strut carries the loads which result from such failure.
