SUPPLEMENTARY INFORMATION: AD 2021-09-03, Amendment 39-21516 (86 FR 
20266, April 19, 2021) (AD 2021-09-03), requires repetitive 
replacements of the emergency locator transmitter (ELT) antenna and 
repetitive inspections for damage of the exterior fuselage skin around 
the ELT antenna attachment area, as specified in TCCA AD CF-2021-10, 
dated March 18, 2021 (TCCA AD CF-2021-10). That AD applies to certain 
Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 
airplanes.

Need for the Correction

    As published, the TCCA AD number specified in paragraphs (h)(1) and 
(2) of the regulatory text of AD 2021-09-03 is incorrectly identified 
as ``TCCA AD CF-2020-10,'' where the correct identification is ``TCCA 
AD CF-2021-10.''

Related Service Information Under 1 CFR Part 51

    TCCA AD CF-2021-10 describes procedures for repetitive replacements 
of the ELT antenna with a new ELT antenna and repetitive inspections of 
the exterior fuselage skin around the ELT antenna attachment area for 
damage (including cracking). This material is reasonably available 
because the interested parties have access to it through their normal 
course of business or by the means identified in the ADDRESSES section.

Correction of Publication

    This document corrects multiple errors and correctly adds the AD as 
an amendment to 14 CFR 39.13. Although no other part of the preamble or 
regulatory information has been corrected, the FAA is publishing the 
entire rule in the Federal Register.
    The effective date of this AD remains May 4, 2021.
    Since this action only corrects references to a TCCA AD number, it 
has no adverse economic impact and imposes no additional burden on any 
person. Therefore, the FAA has determined that notice and public 
procedures are unnecessary.
