Exclamation pitot static errors checklist.

After a personal minor run of pitot static errors and subsequent investigation of previous accidents caused by such errors (e.g. the US 727 with pitot icing, the 737 off the Domenican Republic, the one in Peru etc.) I am trying to compile a list that will cover all the possible errors involved with the pitot static system.

The format I think would work would list the symptom of the primary instrument, secondary effects and thirdly a remedy if possible.

Could PPRuners add to the list the ones they have themselves personally experienced. After a raft of these, we can collate them and print it out to lie around the back of the flight bag for reference on a dark and stormy night.

I will begin with one I had the other very very very dark night.


Aircraft
B200

SYMPTOM
Pilot's AirSpeed indicator reducing rapidly about 5 seconds after takeoff.

SECONDARY EFFECTS
Nil

CAUSE
Leaking face on the AirSpeed Indicator

Remedy
1. Push very gently on the ASI to try and seal it
or
2. Depressurise the cabin.
