When perusing an NTSB file relating to a kitfox engine out/substantial damage deal about two years old (CEN17LA065); I found this comment buried in the text ".....The pilot then performed a takeoff from runway 22 and entered a left crosswind, during which the pitot tube rotated sideways resulting in an airspeed indication of 0 knots......."



Back when we built our Kitfox, I wondered about the potential for this kind of thing to happen as the fixture is a single failure point. That inspired me to make a bracket to secure the pitot tube in addition to the compression fitting.



Now, I know, we all practice and should be able to operate an airplane without a referring to the ASI, which I do; however, the ASI is a good thing not to fail unnecessarily for a number of reasons.



Wondering if anyone else has had a deal like this with a pitot tube coming loose?
