Airworthiness Directive · Amendment 39-21617 · Time limits/maintenance checks
Bombardier, Inc., Airplanes
This AD applies to all Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL- 600-2B16 (601-3A, 601-3R and 604 Variants) airplanes. This AD was prompted by reports of corrosion on the passenger door internal structure of in-service airplanes. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. 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 incorporate the information specified in the applicable time limits/maintenance checks (TLMC) revision specified in figure 1 to paragraph (g) of this AD. The initial compliance time for doing the tasks is at the time specified in the TLMC, or within 30 days after the effective date of this AD, whichever occurs later.
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.
