Replacement Of Fuel Pipes - Magni Gyro M16C Ordinary Maintenance Manual

3.16 REPLACEMENT OF FUEL PIPES
WARNING DANGER:
A visual check of all visible fuel lines needs to be done as a pre‐flight check. Pipes must not show
abrasions, cuts or wear marks.
Vulnerable points will be close to the clamps where longitudinal cuts of the outer covering may occur because of
ageing.
Furthermore, the fuel system must not show any leaking or marks of undue rubbing on the pipes.
If some of the anomalies cited above are found during the visual check, the replacement of the fuel pipes becomes
necessary. Follow the procedure described below.
3.16.1 FUEL PIPES REPLACEMENT PROCEDURE
(See Fig. 3.16/1 and 3.16/2)
1. Before starting verify that the engine's ignition key and push‐button are in OFF position and that all the
breakers are switched OFF;
2. Examine the complete layout of the fuel pipe and of the fixing systems pn 176 along the line taken into
account;
3. Loosen the fixing clamps pn 176 of the pipe that needs replacement;
4. Remove the fuel pipe pn 175 from the connections of the various devices, paying attention to possible
spilling or loss of fuel, especially if the pipe pn 175 is placed lower than the fuel level inside the tank;
5. Replace the damaged fuel pipe pn 175 with a new pipe of the same length; respect the original fuel line
layout and its fixing systems.
6. Insert the new pipe in the connections of the devices concerned and fix it with the special clamps pn 176
(replace these clamps if possible);
7. If the gyroplane has a ROTAX 914 engine and if some pipe upstream the fuel filter pn 274 (10, fig. 3.16/2)
has been replaced, the bleeding of the system is required. Therefore remove the delivery pipe from the
pressure regulator (7);
8. Fit a connection with an extension to the delivery pipe (11, fig. 3.16/2) so as to extend the line to an
external can;
WARNING DANGER:
9. Check that there are no people or objects close to the power plant;
10. Insert the 10 A Equipment (2) and 20 A Generator (3) breakers;
11. Put the MASTER switch (4) in ON position;
12. Put the fuel electric pumps switches (5) and (6) in ON position and let them function for approx. 10
seconds to allow the cleaning of the pipe inside and the complete bleeding of the system.
