Brief Description: 2 Leak tested static and pitot lines
I used a syringe to pressurize the pitot lines holding the airspeed indicator at 90 kts for 1 minute with no movement.
I then pulled a vacuum on the static lines with the syringe and watched the VSI jump to about 1500 ft/ and then settle down after the plunger was stil
The vacuum held the altimeter at 1080 ft and the airspeed to 70kts for a minute with no movement and then settle down after the plunger was still.
I then vented the static lines using the alternate source switch, and everything went back normal with altimeter returning to 820 ft (my home altitude.)
