2020-02-19 BOMBARDIER, INC.: ( c o r r e c t i o n )
Amendment 39-19831; Docket No. FAA-2019-0720; Product Identifier 2019-NM-117-AD.

TDATA NOTE: The FAA found paragraph (h)(2) specifies  an incorrect service
            information reference for performing the inspection. This doc-
            ument corrects that error. In all other respects, the original
            document remains the same.

(a) EFFECTIVE DATE

    This AD is effective March 18, 2020.

(b) AFFECTED ADS

    This AD replaces  AD 2003-09-04 R1,  Amendment 39-13305  (68 FR 54985,
    September 22, 2003) ("AD 2003-09-04 R1").

(c) APPLICABILITY

    This AD applies to Bombardier, Inc.,  Model CL-600-2B19  (Regional Jet
    series 100 & 440) airplanes,  certificated  in  any  category,  serial
    numbers 7003 through 8999 inclusive.

(d) SUBJECT

    Air Transport Association (ATA) of America Code 53, Fuselage.

(e) REASON

    This AD was prompted  by a report of  fatigue cracks occurring on  the
    pressure floor skin at fuselage stations (FS) 460 and 513.  The FAA is
    issuing this AD to address such fatigue cracks, which could result  in
    failure of the pressure floor skin and consequent rapid  decompression
    of the airplane during flight.

(f) COMPLIANCE

    Comply  with this  AD within  the compliance  times specified,  unless
    already done.

(g) MAINTENANCE PROGRAM REVISION FOR SERIAL NUMBERS 7003 THROUGH 8079

    For  airplane  serial numbers  7003 through 8079 inclusive:  Within 30
    days from the effective date this AD,  revise the existing maintenance
    or inspection program, as applicable, by incorporating the information
    specified  in  Airworthiness Limitations  (AWL)  task number 53-41-149
    specified   in   Bombardier  CL-600-2B19   Airworthiness  Requirements
    Temporary Revision 2B-2265, dated July 19, 2018,  to Appendix B - Air-
    worthiness Limitations,  of  Part 2  of the Bombardier Maintenance Re-
    quirements Manual.

(1) The initial compliance time  for doing the task is  at the time speci-
    fied in figure 1  to paragraph (g)(1)  of this AD,  or  within 90 days
    after the effective date of this AD, whichever occurs later.

DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2019-0720; Product Identifier 2019-NM-117-AD; Amendment
39-19831; AD 2020-02-19]
RIN 2120-AA64

Airworthiness Directives; Bombardier, Inc., Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; correction.

-----------------------------------------------------------------------

SUMMARY: The FAA is correcting an airworthiness directive (AD) that
published in the Federal Register. That AD applies to certain
Bombardier, Inc., Model CL-600-2B19 (Regional Jet series 100 & 440)
airplanes. As published, paragraph (h)(2) of that AD specifies an
incorrect service information reference for performing the inspection.
This document corrects that error. In all other respects, the original
document remains the same.

DATES: This correction is effective March 18, 2020.
The effective date of AD 2020-02-19 remains March 18, 2020.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of March 18,
2020 (85 FR 7857, February 12, 2020).

ADDRESSES: For service information identified in this final rule,
contact Bombardier, Inc., 400 Cote-Vertu Road West, Dorval,
Quebec H4S 1Y9, Canada; Widebody Customer Response Center North
America toll-free telephone 1-866-538-1247 or direct-dial telephone 1-
514-855-2999; fax 514-855-7401; email ac.yul@aero.bombardier.com;

You may examine the AD docket on the internet at https://www.regulations.gov
by searching for and locating Docket No. FAA-2019-
0720; or in person at Docket Operations between 9 a.m. and 5 p.m.,
Monday through Friday, except Federal holidays. The AD docket contains
this final rule, the regulatory evaluation, any comments received, and
other information. The address for Docket Operations is U.S. Department

FOR FURTHER INFORMATION CONTACT: Andrea Jimenez, Aerospace Engineer,
Airframe and Mechanical Systems Section, FAA, New York ACO Branch, 1600
Stewart Avenue, Suite 410, Westbury, NY 11590; telephone 516-228-7330;
fax 516-794-5531; email 9-avs-nyaco-cos@faa.gov.

SUPPLEMENTARY INFORMATION: AD 2020-02-19, Amendment 39-19831 (85 FR
7857, February 12, 2020) (``AD 2020-02-19''), currently requires
revising the existing maintenance or inspection program, as applicable,
to incorporate new or more restrictive airworthiness limitations;
revising the applicability to include additional airplanes; and
revising certain compliance times. That AD applies to certain
Bombardier, Inc., Model CL-600-2B19 (Regional Jet series 100 & 440)
airplanes.

Need for the Correction

As published, paragraph (h)(2) of AD 2020-02-19 contains a
typographical error. Paragraph (h)(2) of the AD incorrectly specifies
Bombardier CL-600-2B19 Airworthiness Requirements Temporary Revision
2B-2265, dated July 19, 2018, to Appendix B--
Airworthiness Limitations, of Part 2 of the Bombardier Maintenance
Requirements Manual, for performing the inspection. The correct service
information for performing the inspection is Bombardier CL-600-2B19
Maintenance Requirements Temporary Revision 2B-2266, dated July 19,
2018, to Appendix B--Airworthiness Limitations, of Part 2 of the
Bombardier Maintenance Requirements Manual.

Related Service Information Under 1 CFR Part 51

Bombardier has issued Bombardier CL-600-2B19 Temporary Revision 2B-
2265, dated July 19, 2018, to Appendix B--Airworthiness Limitations, of
Part 2 of the Bombardier Maintenance Requirements Manual; and
Bombardier CL-600-2B19 Temporary Revision 2B-2266, dated July 19, 2018,
to Appendix B--Airworthiness Limitations, of Part 2 of the Bombardier
Maintenance Requirements Manual. These temporary revisions describe
airworthiness limitations for inspections of the pressure floor skin.
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 an error 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 March 18, 2020.
Since this action only corrects a service information reference for
the inspection, 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

Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
