Bombardier, Inc., Airplanes
This AD applies to all Bombardier, Inc., Model BD-100-1A10 airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all 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 specified in the tasks specified in figure 1 to paragraph (g) of this AD, of Part 2, “Airworthiness Limitations,” of the applicable Time Limits/Maintenance Checks (TLMC) manual. The initial compliance time for doing the tasks is at the interval specified in the applicable TLMC manual specified in figure 1 to paragraph (g) of this AD, or within 60 days after the effective date of this AD, whichever occurs later.

Note 1 to paragraph (g): The asterisk (or “one star”) with the last three digits of the task numbers listed in figure 1 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.
