Airworthiness Directives; Bombardier, Inc., Airplanes Federal Aviation Administration FAA, Department of Transportation DOT.
ACTION: Final rule.
AGENCY:

The FAA is adopting a new airworthiness directive AD for certain Bombardier, Inc., Model BD7001A10
airplanes. This AD was prompted by a report of smoke and signs of an overheating condition from the emergency light battery ELB due to excessive corrosion surrounding the internal lead acid batteries, which caused an electrical short circuit that led to the smoke and overheating condition. This AD requires an inspection to determine the last replacement date of the ELB, and replacement if necessary. This AD also requires the incorporation of a new maintenance task into the existing maintenance or inspection program. The FAA is issuing this AD to address the unsafe condition on these products.
DATES: This AD is effective March 30, 2021.
The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD
as of March 30, 2021.

SUPPLEMENTARY INFORMATION:
Discussion Transport Canada Civil Aviation TCCA, which is the aviation authority for Canada, has issued Canadian AD
CF202007, dated March 17, 2020 also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI, to correct an unsafe condition for certain Bombardier, Inc., Model BD
7001A10 airplanes. You may examine the MCAI in the AD docket on the internet at https www.regulations.gov by searching for and locating Docket No.
FAA20200843.
The FAA issued a notice of proposed rulemaking NPRM to amend 14 CFR
part 39 by adding an AD that would apply to certain Bombardier, Inc., Model BD7001A10 airplanes. The NPRM
published in the Federal Register on September 17, 2020 85 FR 58010. The NPRM was prompted by a report of smoke and signs of an overheating condition from the ELB due to excessive corrosion surrounding the internal lead acid batteries, which caused an electrical short circuit that led to the smoke and overheating condition. The NPRM proposed to require an inspection to determine the last replacement date of the ELB, and replacement if necessary. The NPRM
also proposed to require the incorporation of a new maintenance task into the existing maintenance or inspection program. The FAA is issuing this AD to address smoke and an overheating condition of the ELB due to corrosion, which could cause fire onboard the airplane. See the MCAI for additional background information.
Comments The FAA gave the public the opportunity to participate in developing this final rule. The following presents the comment received on the NPRM and the FAAs response to that comment.
