Airworthiness Directives; Bombardier, Inc., Airplanes

FAA / Federal Register · 2019-23529

The FAA proposes to supersede Airworthiness Directive (AD) 2003-09-04 R1, which applies to certain Bombardier, Inc., Model CL-600- 2B19 (Regional Jet series 100 & 440) airplanes. AD 2003-09-04 R1 requires revising the airworthiness limitations for certain structural inspections; repair if necessary; and submission of inspection findings to the airplane manufacturer. Since the FAA issued AD 2003-09-04 R1, the agency determined that additional airplanes are affected, that new or more restrictive airworthiness limitations are necessary, and that the compliance time must be revised to include a phase-in time for certain tasks. This proposed AD would revise the applicability to include additional airplanes; revise certain compliance times; and require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products.
