Summary
We propose to supersede Airworthiness Directive (AD) 2014-03- 05, for certain Bombardier, Inc. Model BD-700-1A10 airplanes. AD 2014- 03-05 currently requires modification of the air data probes and sensors. Since we issued AD 2014-03-05, we have determined that additional airplanes are affected by the unsafe condition. This proposed AD would add airplanes to the applicability. We are proposing this AD to detect and correct an unannunciated failure of two pitot static probe heaters, which could affect controllability of the airplane in icing conditions.
