10.2 MANUAL FLAP LEVER ASSY
10.2.1 DESCRIPTION
Many Jabiru Aircraft are fitted with a manual flap system similar to that shown in Figure 92. In these
systems the pilot pulls down on the lever to lower the flaps.
3 positions are available: up, first stage and second stage. The positions are controlled by the
position of holes in the lever mounting plate.
10.2.2 REMOVAL
Apply heavy duty tape or similar to both wing flaps, holding them up.
Remove the cotter pin and nut from the lever. Remove the lever from the mount plate.
Remove the screw holding the drive shaft to the handle.
WARNING
Do not allow flaps to drop when disconnected from the handle or damage to the flaps, wings or
fuselage may result.
WARNING
All spherical rod end bearings must be fitted with a large washer on the outside of the through-
bolt to prevent the bearing case and cable releasing in the event of a bearing failure.
10.2.3 INSPECTION & REPAIR
Visually inspect the handle for wear or cracking of the fiberglass. Small cracks between the moulded
handgrip and the structural plate forming the handle may be repaired using 5-minute araldite.
Inspect hardware for damage and replace as necessary.
10.2.4 INSTALLATION
For installation reverse the removal procedure.
Ensure tape is removed from flaps and an operational test carried out before use.
10.3 ELECTRIC FLAP DRIVE ASSEMBLY
10.3.1 DESCRIPTION
The flap position controlling switch uses a manual toggle switch to control the flap deflection.
A linear actuator is mounted in the wing root (inside the cabin) and drives the flap cross shaft directly.
Drawings of the systems are shown as Figure 97 through to Figure 103
10.3.2 REMOVAL
Apply heavy duty tape or similar to both wing flaps, holding them up.
Un-bolt the motor from the flap cross shaft, position indicator and mounting bracket.
Disconnect motor wires. Ensure that wires are marked to allow re-assembly in the same orientation.
Remove actuator.
WARNING
Do not allow flaps to drop when disconnected from the motor or damage to the flaps, wings or
fuselage may result.
WARNING
All spherical rod end bearings must be fitted with a large washer on the outside of the through-
bolt to prevent the bearing case and cable releasing in the event of a bearing failure.
