The company inspection showed that the so-called pitot tubes installed in the nose section of the plane were clogged with bugs and apparently indicated incorrect speeds at the time of incident, leading the pilots to fail to carry out appropriate operations.
That statement is not at all correct. "Carrying out appropriate operations" would be realizing you have an airspeed malfunction and aborting the take off roll. If the plane would have crashed, it would have eventually been pilot error. I bet the pilots still get in trouble for this even though there was no crash. You should never crash a plane or even come close because of one single instrument fails, especially as an IFR pilot (which these guys obviously were).
Getting a pitot tube clogged isn't that uncommon either. I had it happen back east on short final in a Piper Arrow. The airspeed dropped from 85 to 40 to about 20 in a matter of 5 seconds. At first it was alarming until your brain has a few seconds to work it out and you realize you have an instrument failure, then its no big deal.
