Just trying to think of accidents attributable to instrument failure...
Air India lost a 747 of the coast of Mumbai in 1978 (ADI/INS)
EMB 120 at Leeds in mid 90s (ADI)
Surely must be more...Air Florida, you cannot quote a PPRuNe thread as approved data.

I believe that, statistically, the vacuum pump is the most unreliable part of a GA aircraft's systems (BTW). This might help.
