3 questions.
- did you do and emergency gear extension test? From your description of how you
accomplished the gear retraction test, you did not mention you tested the emergency
gear extension.
- did you try retracting and extending the gear from the rear cockpit?
- if you did attempt to retract and extend the gear from the rear cockpit, did
you listen for for the same air leak you heard coming from the front cockpit?

What do I think??? I think you seem to be a person willing to take risks
which are way out of proportion to the reward. However that being said, it
would appear that you are in need of replacing your QSF-2A valve---OR----
you have a gear actuator leaking and that air is venting out of your front
gear valve. Dennis asks good questions, answers will help sort this all
out.

Hi ,
thank you for your advices.
we raise the plane and tested the gear retraction.
it was ok with the remaining air at 25 atm, we tested up and down 4 times
till the air remains at about 10 atm.
it works well that is strange.....
i ve noticed an air leak inside the main corp of the front gear handle when
gear up position,
perhaps the front gear handle to replace ?
what do you think about that Doug?

This was a good way to hurt yourself, and your friends, and to impose stress loads
in places that were never designed for same.
This was ignoring every bit of advice from every expert on this list that took
the time to answer.
This was not making lemonade. This was careless and reckless.
Good Day.

Hello again,
so I've made a flight this evening and the same problem appears again: after take
off the gear do not retract.., visualy from outside, the main gear moved about
30 from vertical position. Gear handle was positionned down , 3 greens and
land safely .
yesterday evening when acft was raised, I've done 4 test up/down and its look like
good. pressure at the beginning was 25 and at the 4th 12 remaining .`
I do not test the emergency extension.
its is not possible to move the rear gear handle as the UK CAA blocked it as also
for the Flaps rear handle.. (Im under UK registration)
this morning i refiled the air bottle at 45atm before this evening start up, i
took off with 35 and landed also with about 35 atm
the QS2 valve isn't for the brake repartition?
thanks for help
Bruno

Bruno,
The correct p/n is QSF-2A of which there are three in your aircraft, both
flap valves and the fwd gear valve.
You are correct the QS2 is the brake differential valve in the belly.

Bruno-
Recommend you pull and check all 8 diverter valves (2 per gear and two for flap
control) and rebuild or replace as necessary. Most likely your issue.
