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").

(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.
