2020-03828. 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—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

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

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

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

§ 39.13

[Corrected]

2. The FAA amends § 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”).

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.

(2) For airplanes on which Bombardier Service Bulletin 601R-53-067, Bombardier Service Bulletin 601R-53-077, and AWL task number 53-41-194 have been done, the inspections in AWL task number 53-41-149 are not required in the areas covered by doublers at FS460 and FS513.

(3) For airplanes on which the initial inspection has been 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-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, within 10,000 flight cycles from the previously accomplished inspection.

(h) Maintenance Program Revision for Serial Numbers 8080 Through 8999

(1) For airplane serial numbers 8080 through 8999 inclusive: Within 30 days from the effective date of this AD, revise the existing maintenance or inspection program, as applicable, by incorporating the information specified in AWL task number 53-41-193 specified in Bombardier CL-600-2B19 Airworthiness Limitations Temporary Revision 2B-2266, dated July 19, 2018, to Appendix B—Airworthiness Limitations, of Part 2 of the Bombardier Maintenance Requirements Manual.
