5.4
Unscheduled Maintenance Checks
5.4.1
General
Unscheduled maintenance is required due to abnormal loads such as severe turbulence or
heavy landings. The pilot is responsible for identification of these extreme operating
conditions and identification of the affected components. Where damage is found further
checks should be carried out upon areas that may also be affected.
Thorough checks should also be carried out after transportation of the aircraft, and after
extended storage periods.
5.4.2
Inspection after Heavy Landing
Check shock absorbers for normal operation and correct length of the sliding tubes.
Check all attachment points and members of the suspension system, rear landing gear and
front fork. Check all welded lugs for bending or cracking of paint, which may indicate
permanent deformation of the area. If any permanent deformation is identified then a
more rigorous inspection of the rest of the aircraft is necessary, as permanent deformation
indicates that extreme forces have been experienced by the aircraft.
5.4.3
Checking for Deformation
A straight edge may be used on the tubing to ascertain straightness.
Attachment Points
Check attachment points of the wing to the base, including the main hang bolt, wheel
axles and bearings. The wing should also necessarily be checked after any heavy landing
because the forces are transmitted through the wing structure.
Check the main structure including the upper beam, landing gear attachment points and
engine mount.
Check that all other components attached to the base are in place and properly secured.
Seat Frame
If the airframe has experienced unusual loads then the seat frames should be checked
thoroughly. The weight of the pilots during impacts may damage the seat frame.
5.4.4
Inspection after Heavy Turbulence
Check all components attached to the base are in place and properly secured, any other
items that may have shifted due to in flight movement should also be checked on a
regular basis.
Turbulence is more likely to structurally affect the wing of the aircraft rather than the
trike. The Wing Maintenance manual should be consulted for instructions that pertain to
the wing.
