9. Routine
Maintenance
9.1
The aircraft is to be maintained to Microlight Maintenance Schedule MMS-1,
which is contained in BMAA Technical Information Leaflet 020. Engine
maintenance should be in accordance with the engine maintenance manual.
9.2
The following additional points are required during routine airframe
maintenance and inspection:
•
When inspecting control runs it is good practice to rotate pulleys 90
0
to
reduce wear spots.
•
If a wood hub propeller is fitted, check securing bolts for tightness after
seasonal changes in temperature and humidity in addition to the check
C period.
•
When checking control runs check the forward attachment of the
aileron torque tube. This has a 6mm bolt acting as pivot for the primary
aileron drive horn. This will be subject to wear over time. Grasp the
torque tube at the forward end and test for excessive wear by moving
up and down.
9.3
The following exceptions are made to MMS-1 in the maintenance and
inspection of the Skyranger:
•
Wing battens should not be removed to check profile. An external
template of batten profile can be made on stiff card or plastic and
shape can be checked by lying the template externally over the battens
whilst still in place.
•
It should not be necessary to remove fuselage covering to inspect the
rear fuselage structure.
•
Do not clean spark plugs. Simply replace when they have reached their
specified life.
