What: Wideroe de Havilland Dash 8-100 en route from Sogndal to Forde
Where: Bergen
When: Mar 2nd 2010
Who: 16 passengers and 3 crew
Why: While on route, the pitot heating system failed. The resulting nreliable airspeed indications convinced the crew to divert to Bergen, where they made a safe landing.
Offhand, I think this may be the first that I recall pitot tube issues on a de Havilland Dash 8-100. I wonder if these were thales tubes; and I wonder if airspeed can not be better determined with a more robust methodology. If I were a manufacturer, I would certainly have my engineers thinking about developing alternative technologies to bring to market.
