Reminder of Hydraulic Servicing for the Fouga

After talking with Fouga owners about the servicing of the Hydraulic,
I want to review the procedures:

- First : Start the left engine to have 250 HPZ on the normal and emergency hydraulic systems
            Operate flaps, speed brakes, ailerons boost if you have some.  
            Reconfigure aircraft in a clean mode ( flaps retracted, speed brakes in)


- Shut down the engine and open the small cap on the left, on the main hydraulic reservoir
   ( the big cap in the center is the access to replace the main hydraulic filter)
- Service the hydraulic up to the top of the center spigot that you will see when you open the small cap.
- If you over serviced, open the little valve with the castle wheel on it (lower right hand corner), it will drain   under the aircraft to the normal level. Do not forget to close the valve after. 
- Close the small cap, and this is done.

Never try to check the hydraulic level with no pressure inside the hydraulic systems because when you will open the overflow valve or the small cap, hydraulic will come out of the hydraulic reservoir

Jaguar that we imported in the US

 This is a Jaguar that we imported in the US last year to be in the future back in flying condition

A lot of money and tender loving care will be needed

Marbore Borescope, why it is important!

A fouga owner purchased a Marbore engine without doing a borescope.

After contacted me, I performed a borescope inspection to see the shape and health of the engine.

This is what I found :

 Conclusion : Engine good to be sent to the scrap yard

Tip tank spigot

This is a other reason why you have to check the tip tank spigot.
A fellow Fouga owner was doing a annual inspection and this is what he found when he
removed the tip tanks.
When you install the tip tanks, be sure to check the right torque on the main nut and back up nut.

Reminder of Fuel filter who could be deadly

I was inspecting a Fouga and the bypass indicator of the main fuel filter on the center top of the housing was out.
First indication of a problem.
When I removed the old fuel filter, the spring on the fuel filter was installed on the top instead to be positioned on the bottom.
Conclusion: after the installation of the main fuel filter check the bypass pop out.
If the bypass is out and does not want to reset in a flush position, the spring of the fuel filter is installed on the top. Remove the fuel filter again and install it with the spring on the bottom, check the pop out and install the safety wire,

Group Yahoo for Fougacm170

Hi,
I created  http://groups.yahoo.com/search?query=fougacm170 
A yahoo group for people to be able to post questions and reply to other who have questions about the Fouga or comments.
I put a file concerning the Israeli fouga engines.
The compressors attachments was modified in France in 1976 due to the same problems.

Canopy seal who does not deflate

I was called to fix some  squawks on a Fouga .
Main concern of the owner was smoke in the cockpit.
I ran the engines to 22,500 rpm on the ground for 5 minutes, checking at the same time the pressurization and I could not reproduce the problem, pressurization working perfectly.
Owner, his son and me did the servicing of the aircraft, then Sunday night we did the test flight.
After take off, with pressurization on, we had no smoke but ice particle and condensation due the high humidity coming out of the ACM diffuser, so I increased the temp control to full hot, water came out of the vents, then after 1 minute, back to medium cold and everything was normal. A couple of aerobatic evolutions, all check fine, back to earth.
Out of the cockpit, and closing the canopy : the canopy seals stay inflated.
I checked the canopy selector valve, look like it's working.
After 20 minutes the owner could close the canopy.
That evening looking down the runways lite, I called my friend Didier and talked about the problem.
The outlet vent for the canopy seals could be plugged.

and yes it was. Plug removed, problem solved.
