e) Periodical overhaul
For the engine, refer to chapter 9 of the engine maintenance manual.
Often clean the radiator to avoid obstruction due to grass or debris.
−
Every 50 hours of flight time or 6 months (first achieved):
•
Check the engine support: rubber mounts and fastening springs.
•
Check seams on welded assemblies, corrosion*, cracks, holes, movement on various
assemblies (engine support, front frame, back frame, upper beam, gear triangles, front
fork, pedal assembly, fairing fastening, coolers).
*
Corrosion: the trike structure is made of stainless steel 304 and 304L. This type of
steel, in spite of its denomination, is sensitive to corrosion, particularly around
welding seams. The structure is protected by a highly resisting coating (oven-heated
epoxy). The happening of corrosion makes blisters and takes the finish off. It is
necessary to treat immediately the corroded patches by scraping, cleaning and then
protecting them.
In hostile environment (notably sea), the corrosion may appear and grow faster, so it
should be checked more frequently.
•
Check rear shock absorber air pressure. Insufficient pressure will cause the trike
suspension units to subside under load or lean excessively during turning on the
ground or in cross-winds. Fill to 25 bar using a special hand-pump where required or
ask your dealer.
•
Every 25 landings maximum
, check the length of the sliding tubes of the “shock
absorber” set. The difference (sets at full extension) should not exceed 2 mm. If not,
you should arrange for an overhaul. Moreover the overhaul of the “shock absorber” set
has to be made every
400 take-off or 3 years of use.
•
Check condition and running of throttle, brake and fork control cable.
Warning: never
put grease or oil on cables
; a self-lubricating « POM® » sheath keeps them working
properly.
−
Every 100 hours of flight time:
•
Change hoses, fuel filter, and primer bulb.
•
Change throttle, brake and fork control cables, all bolts involved in frequent
mounting/dismounting operations (hanging point, front strut and upper arch), engine
and propeller mounting bolts.
•
Change the 2 front wheel shock absorbers.
•
Change the lower and upper bearings of the front fork.
•
Check condition of tires, rims, and wheel bearings front fork and wheel axles.
•
Check condition of brake discs as well as brake pads.
•
Check level of brake’s liquid in each pump.
•
Check upholstery, seams of under-seats, back of seats fastening.
•
Check the front strut at lower and upper fixations level.
