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).

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--

[[Page 10979]]

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

reference, Safety.

Adoption of the Correction

    Accordingly, pursuant to the authority delegated to me by the 
Administrator, the Federal Aviation Administration amends part 39 of 
the Federal Aviation Regulations (14 CFR part 39) as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Corrected]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2020-02-19 Bombardier, Inc.: Amendment 39-19831; Docket No. FAA-
2019-0720; Product Identifier 2019-NM-117-AD.

(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'').

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--Airworthiness Limitations, of Part 2 of the Bombardier 
Maintenance Requirements Manual.
    (1) The initial compliance time for doing the task is at the 
time specified in figure 1 to paragraph (g)(1) of this AD, or within 
90 days after the effective date of this AD, whichever occurs later.

067, Bombardier Service Bulletin 601R-53-077, and AWL task number 
53-41-194 have been done, the inspections in AWL task number 53-41-

accomplished at 18,325 or more total flight cycles, and no cracks 
were found, as of October 7, 2003 (the effective date of AD 2003-09-
04), the repetitive interval of 10,000 flight cycles starts from the 
completion date of the initial inspection.
    (4) For airplanes that were previously inspected using AWL task 
number 53-41-193, perform an inspection using the information 
specified in AWL task number 53-41-149, provided in Bombardier CL-

Requirements Manual. Except as specified in paragraph (h)(2) of this 
AD, the initial compliance time for doing the task is at the time 
specified in Bombardier CL-600-2B19 Airworthiness Requirements 
Temporary Revision 2B-2266, dated July 19, 2018, to Appendix B--
Airworthiness Limitations, of Part 2 of the Bombardier Maintenance
