Nose landing gear:
Verify the nose landing gear leg and attachment plate shape, welding, bolts, the fork shape and
wheel axis, the axis bolts closure, its safety wire, the ring nut closure. Verify also the lower and upper
leg constrains, with plastic guide, the supporting structure, the Vulcolan end of run, the steering rod
and uniball, check rudder pedals and hinges. Verify the wheel rim and tyre.
For any problem observed, replace the part damaged with a spare new one.
5.2. Fuel system leakage in fuselage
When observed fuel in fuselage, find the source, drain the fuel if required, clean the humid area and
replace the parts affected by the problem. Open all the possible inspection port and let the liquid
evaporate and vapour eliminate. Check all the fuel system connections and perform a pressure test
at 0.3 [bar]. Verify that no additional parts are damaged or corroded by the fuel.
5.3. Wing tank or cup fuel leakage
When observed leakage from wing tank compartment, open the inspection panel and find the source,
drain the fuel if required, clean the humid area and replace the parts affected by the problem. If the
leakage comes from the tank support, replace the entire tank. If the leakage comes from a tank fuel
fitting, installed directly on the tank, replace the fitting, check if the tank hole is capable to support a
new fitting and add sufficient sealant (fuel resistant). If the leakage comes from the cup ring (socket),
verify that the o-ring is correctly installed between the tank and the ring, the ring is not unscrewed. If
this problem occur, replace the entire fuel tank or replace the o-ring adding sufficient sealant,
verifying o-ring positioning during the ring closure.
Verify the cup has the o-ring intact.
5.4. Radiator suspension breakage
If radiator bracket or silent-block are broken, replace the parts. Pay attention to the installation
position by verifying the relative position with the engine cowling.
5.5. Windshield or window cracks or breakage
If a Lexan window is broken or cracked more than 25 [mm], replace entirely. If observed a new crack
within the previous limit, stop the crack making a hole of 1 [mm] diameter at the end of the crack.
