Applicability*9

This AD applies to Bombardier, Inc. Model BD-100-1A10 (Challenger 300) airplanes, certificated in any category, serial numbers 20003 through 20500 inclusive.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

Within 24 months after the effective date of this AD, replace the left and right pitot-static probes with newly designed pitot-static probes, part numbers (P/N) 0856WC3 and 0856WC4 respectively, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 100-34-38, dated January 9, 2014.

Unsafe condition

This AD was prompted by multiple reports of a short circuit between the heater element and the metal sheath of the pitot-static probe heater. We are issuing this AD to prevent degradation of the heating ability of the pitot-static probe heater, resulting in erroneous airspeed indication during flight in icing conditions and consequent reduced controllability of the airplane.

Affected ADs

None.
