Airworthiness Directive · Amendment 39-22048 · Ice and rain protection
Bombardier, Inc., Airplanes
This AD applies to Bombardier, Inc., airplanes, certificated in any category, as identified in paragraphs (c)(1) through (3) of this AD.
(1) Model CL-600-1A11 (600) airplanes having serial numbers (S/Ns) 1001 through 1085 inclusive.
(2) Model CL-600-2A12 (601) airplanes having S/Ns 3001 through 3066 inclusive.
(3) Model CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes having S/Ns 5001 through 5194 inclusive; 5301 through 5665 inclusive; 5701 through 5988 inclusive; and 6050 through 6153 inclusive.
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. This AD was prompted by a report of a wing stall (wing drop/un-commanded roll) during a landing flare. This AD requires revising the existing airplane flight manual (AFM) to incorporate a limitation and procedure for the wing anti-ice (WAI) system in order to mitigate the risk of ice accumulation on the wing leading edges. The FAA is issuing this AD to address the unsafe condition on these products.
Within 60 days after the effective date of this AD: Revise the existing AFM to incorporate the specified sections of the Bombardier or Canadair Challenger AFM revision limitations and procedures for the WAI system specified in figure 1 to paragraph (g) of this AD.
