Airworthiness Directive · Amendment 39-22067 · Time limits/maintenance checks
Bombardier, Inc., Airplanes
This AD applies to Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes, certificated in any category, serial numbers 9001 through 9879 inclusive, 9998, and 60001 through 60033 inclusive.
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by reports of internal corrosion on the inboard flaps found prior to regularly scheduled maintenance checks. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate a certain aircraft maintenance manual (AMM) task. The FAA is issuing this AD to address the unsafe condition on these products.
Within 30 days after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to include the information specified in Task 57-51-00-290-801, “Special Detailed Inspection of the Inboard-Flap Internal Ribs,” of Subject 57-51-00, “Flaps,” in Chapter 57, “Wings,” of the applicable Bombardier Aircraft Maintenance Manual (AMM) identified in figure 1 to paragraph (g) of this AD and to include the following compliance times for Task 57-51-00-290-801: Within 60 months after the effective date of this AD (for the initial compliance time), and repeat thereafter at intervals not to exceed 60 months.
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 or intervals, are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (i)(1) of this AD.
