Hi,

Of course you will want to be careful so that any debris that is knocked
loose does not blow into your airspeed indicator or speed-to-fly variometer.

Is the pitot mounted in the nose or tail?

I would recommend removing the tubing and replacing it if possible - for the
reason mentioned above.

I would try varios rods and pipe cleaners. Spraying silicone lubricant onto
the rod or cleaner may help it slide inside the tube.

I sell small filters that could be used to keep debris out of your
instruments. You would install close to the instruments - downstream of
the blockage. They are quite inexpensive.

The Pito in my Twin Astir is blocked.
The glider was stored for 6 monthes. Perfect befor - totaly blocked
after.
The blockage is between rear seat to the tail.
I'v tried to blow / suck as hard as can without any air movments.
It is imposible to insert a wire from the pito at the tail - probbaly a
90 degree connection inside.
Trying to push a 3/32 cable into the tube, it gets harder after 4 feet
because the vinyl tube is sticky and a lot of friction.

Any ideas?

Maybe a small animel crowled inside and died and now is swallen.
Should I send ants inside ? ;-
