LANDING LIGHT(S)
7.9.1 DESCRIPTION
Landing / taxi lights are optional equipment for Jabiru Aircraft.
Night-VFR variants have a wing-strut mounted housing on each wing strut with narrow-beam high
intensity lights fitted. Smaller wide-beam lights are used in similar housings for day-VFR aircraft.
7.9.2 REMOVAL, INSPECTION & INSTALLATION
Remove the clamping screw at the trailing edge of the light housing.
If required, carefully remove silicone adhesive between housing and strut
– taking care not to
damage the paint or the light housing.
Remove the housing from the strut then disconnect the light wires.
Remove light mounting screws to allow removal of the light from the housing.
Visually inspect the light housing for cracks or damage. Check the strut for chaffing, wear or
corrosion. Inspect the wires for damage to the insulation, corrosion on the connectors etc.
For installation, reverse the steps given above. Note that silicone adhesive (or similar) is required to
prevent the housing chaffing on the strut.
7.10 LANDING LIGHT ADJUSTMENT (NIGHT-VFR MODELS)
The alignment of lights for aircraft carrying out Night-VFR operations must be checked as a part of
the 100-hourly inspection.
The lights must be aimed to focus on the ground approximately 15 meters in front of the aircraft.
Before this procedure is carried out ensure that the wires are connected and each light housing
secure on the wing strut.
Each housing must have at least one slotted light mounting hole (refer Figure 51). In some cases
both holes must be slotted to achieve proper targeting.
Note that Figure 51, Left, shows the light during a test fit; the trim ring, internal paint and Aluminium
tape (see Figure 53) have not been fitted yet.
Figure 51
– Light Installed (Left) & Slotted Hole In Housing
Alignment is carried out in a dark hangar or outdoor at night. Turn the lights on and mark a distance
15 meters away from the wing.
Aim the lights at the focal points given in Figure 52. Lock the position of the lamp by tightening the
screws once aiming is complete.
Ensure that the when the “TAXI” light is selected the light shown on the right of Figure 52 illuminates
– i.e. the TAXI light is aimed to shine on the centre of the taxiway 15m in front of the aircraft. The
LANDING light is aimed straight ahead.
Slot ½” long (13mm) maximum –
measured from the edges of the hole.
