Airworthiness Directive · Amendment 39-22763 · Time limits/maintenance checks
Bombardier, Inc., Airplanes
This AD applies to Bombardier, Inc., Model BD-100-1A10 airplanes, certificated in any category, having serial numbers (S/Ns) 20003 through 20500 inclusive, and 20501 through 20959 inclusive.
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-100-1A10 airplanes. This AD was prompted by a determination that new or more restrictive maintenance tasks are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance tasks. The FAA is issuing this AD to address the unsafe condition on these products.
Within 60 days after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to incorporate the information in the tasks specified in figure 1 or 2 to paragraph (g) of this AD, as applicable. The initial compliance time for doing the tasks is at the time specified in the applicable temporary revision (TR) or time limit/maintenance check (TLMC) document specified in figures 1 and 2 to paragraph (g) of this AD, or within 60 days after the effective date of this AD, whichever occurs later. When the information in the applicable TR has been incorporated into the general revision of that Bombardier TLMC, the maintenance or inspection program may be revised using the information in the general revision.
Note 1 to Figure 1 to paragraph (g): The section number in the footer on certain pages of the TLMC sections is incomplete (i.e., “05-10-2” instead of “05-10-20” and “05-10-4” instead of “05-10-40”).
Note 2 to Figure 1 to paragraph (g): The asterisk (or “one star”) or double asterisk (“two star”) with the last three digits of the task numbers listed in figures 1 and 2 to paragraph (g) of this AD indicates that the task is an airworthiness limitation task.
After the existing maintenance or inspection program has been revised as required by paragraph (g) of this AD, no alternative actions (e.g., inspections) or intervals may be used unless the actions and intervals are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (i)(1) of this AD.
