SUMMARY: The FAA is correcting an airworthiness directive (AD) that was 
published in the Federal Register. That AD applies to certain 
Bombardier, Inc., Model CL-600-2B16 (601-3A, 601-3R, and 604 Variants) 
airplanes. As published, the AD number specified in the regulatory text 
is incorrect. This document corrects that error and one other minor 
error. In all other respects, the original document remains the same.

SUPPLEMENTARY INFORMATION:

Background

    AD 2021-26-23, Amendment 39-21882 (87 FR 3184, January 21, 2022) 
(AD 2021-26-23), requires repetitive inspections for fuel leakage at 
the engine and auxiliary power unit (APU) fuel pumps, related 
investigative and corrective actions if necessary, an inspection of the 
APU for damage and deformation, repair if necessary, and modification 
of the engine electrical fuel pump (EFP) installation. The AD applies 
to certain Bombardier, Inc., Model CL-600-2B16 (601-3A, 601-3R, and 604 
Variants) airplanes.

Need for the Correction

    As published, the regulatory text of AD 2021-26-23 included the 
following errors:
     The AD number was incorrectly identified as ``2021-21-
23.'' The correct AD number is 2021-26-23.
     The last sentence of paragraph (g) requires use of certain 
service information ``as the effective date of this AD.'' The correct 
compliance time for that requirement is ``as of the effective date of 
this AD.''

Related Service Information Under 1 CFR Part 51

    Bombardier has issued the following service information, which 
describes procedures for repetitive general visual inspections and 
rectifications for any fuel leak from the engine and APU EFP electrical 
wiring conduit outlets. These documents are distinct since they apply 
to different airplane serial numbers.
     Bombardier Service Bulletin 604-28-022, Revision 3, dated 
August 31, 2018.
     Bombardier Service Bulletin 605-28-010, Revision 3, dated 
August 31, 2018.
     Bombardier Service Bulletin 650-28-001, Revision 3, dated 
January 3, 2019.
    Bombardier has also issued the following service information, which 
describes procedures for a detailed visual inspection of the APU for 
any damage or deformations (e.g., cut wires and a broken harness 
assembly of the fuel boost pump connector), modification of the engine 
EFP installation, and repair if necessary. These documents are distinct 
since they apply to different airplane serial numbers.
     Bombardier Service Bulletin 604-28-024, Revision 01, dated 
May 28, 2021.
     Bombardier Service Bulletin 605-28-012, dated June 16, 
2020.
     Bombardier Service Bulletin 650-28-002, dated June 16, 
2020.
    This AD also requires Bombardier Service Bulletin 604-28-022, dated 
October 19, 2015, and Bombardier Service Bulletin 605-28-010, dated 
October 19, 2015, which the Director of the Federal Register approved 
for incorporation by reference as of November 30, 2017 (82 FR 49498, 
October 26, 2017).
    This service information 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 two errors in the regulatory text 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 February 25, 2022.
    Since this action only corrects the AD number and a minor 
grammatical error in the regulatory text, 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.

List of Subjects in 14 CFR Part 39

reference, Safety.

Adoption of the Amendment

    Accordingly, pursuant to the authority delegated to me by the
