WING FLAP CONTROL SYSTEM

10.1 WING FLAP CONTROL SYSTEM
10.1.1 DESCRIPTION

For aircraft with electric flaps the control system comprises a switch mounted on the instrument
panel, a position indicator mounted on the windscreen / door pillar and an electronic linear actuator-
driven common shaft assembly, with pushrods connecting to the flap control surface horns.

Models with manual flaps retain the same shaft assembly inside the cabin, driving the flaps via
pushrod, however in these aircraft a manual lever located above the pilot's door drives the system.

Refer to sections below for details on removal, maintenance and installation of the various parts of
the system.

Due to space constraints not all different variations are shown herein. When ordering spare parts
provide as must detail as possible – part description, aircraft model, serial number etc to Jabiru to
ensure accurate part identification.
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.
10.1.2 OPERATIONAL CHECK

Operate flaps through their full range of travel, observing for uneven or jumpy motion or binding in
the system. Ensure flaps are moving together through their full range of travel.
