static leak
Deja vu
1) There is a connector at the pitot head which consists of rubber tubing and two clamps. This is a problem area and should look first if you have a PITOT LEAK.
Now for static. There are two static ports on the aircraft along with two bottles that collect moisture on each side of forward cabin. This can be a problem area. As far as leaks you start at the altimeter and work backwards. The autopilot, altimeter, blind encoder, etc. The only tube that runs back to the autopilot is routed along the pilot side of the A/C above the headliner.
Many times the tube running up the pilot side window post gets punctured with a screw. The original tubing becomes rather brittle and you may want to consider replacing the tubing with new.
There is no simple proceedure other than isolating the lines.
The Pitot goes thru the wing root. The static does not.
These suggestions cover both possibilities.
