Cant see an iced up pitot tube causing a jet to crash.
Perhaps not a direct result of it, but it has played a role before.

Final report[edit]
On 5 July 2012, the BEA released its final report on the accident. This confirmed the findings of the preliminary reports and provided additional details and recommendations to improve safety. According to the final report,[228] the accident resulted from the following succession of major events:

temporary inconsistency between the measured speeds, likely as a result of the obstruction of the pitot tubes by ice

Investigations later showed that the plane was actually travelling at 220 knots (410 km/h) at the time.[citation needed] The investigation concluded that one of three pitot tubes, used to measure airspeed, was blocked.

That's exactly the kind of complacency that causes crashes! "Don't worry captain, the autopilot will take care of everything..." Not just the pitot tube, but also the static port used by the pressure altimeter.


Because a maintenance worker had failed to remove tape covering the static ports, the air data computers were unable to report the correct airspeed and altitude. The pilots struggled to navigate the aircraft as they were unaware of their true altitude and did not effectively use their alternative means; being midnight, they also had no external visual references. The aircraft wing hit the water and it crashed shortly afterwards.

The findings of the investigation stated that the B-2 crashed after "heavy, lashing rains" caused moisture to enter skin-flush air-data sensors. The data from the sensors are used to calculate numerous factors including airspeed and altitude. Because three pressure transducers had been improperly calibrated by the maintenance crew due to condensation inside devices, the flight-control computers calculated inaccurate aircraft angle of attack and airspeed.
With an estimated loss of US$1.4 billion, it was the most expensive crash in USAF history.
