Airworthiness Directive · Amendment 39-21017 · Ice and rain protection
Bombardier, Inc., Airplanes
This AD applies to all Bombardier, Inc., Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Bombardier, Inc., Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This AD was prompted by a report of a wing stall (wing drop/ uncommanded roll) during landing flare, due to ice on the wing leading edges that was not detected by the anti-ice system. This AD requires revising the existing airplane flight manual (AFM) to include a limitation and normal operating procedure for the wing anti-ice system. The FAA is issuing this AD to address the unsafe condition on these products.
Within 30 days after the effective date of this AD: Revise the existing AFM to incorporate the information specified in paragraphs (g)(1) and (2) of this AD.
(1) Paragraph 3.—“Operation in Icing Conditions” of Section 02-04, “Operating Limitations,” of Chapter 2, LIMITATIONS,” of the Bombardier CRJ Series Regional Jet Model CL-600-2B19 Airplane Flight Manual, CSP A-012, Volume 1, Revision 72, dated July 12, 2019.
(2) Paragraph 5.—“Prior to Landing” of Section 04-02, “Consolidated Procedures” of Chapter 4 “NORMAL PROCEDURES,” of the Bombardier CRJ Series Regional Jet Model CL-600-2B19 Airplane Flight Manual, CSP A-012, Volume 1, Revision 72, dated July 12, 2019.
