Federal Aviation Administration October 30, 2019 – Federal Register Recent Federal Regulation Documents

The FAA proposes to supersede Airworthiness Directive (AD) 2018-19-26, which applies to all Dassault Aviation Model MYSTERE- FALCON 200 airplanes. AD 2018-19-26 requires revising the maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance requirements and airworthiness limitations. Since the FAA issued AD 2018-19-26, the FAA determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would 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.

The FAA proposes to adopt a new airworthiness directive (AD) for certain De Havilland Aircraft of Canada Limited Model DHC-8-400 series airplanes. This proposed AD was prompted by reports of wear on fuel couplings, bonding springs, and sleeves as well as fuel tube end ferrules and fuel component end ferrules. This proposed AD would require repetitive inspections of certain parts for discrepancies that meet specified criteria, and replacement as necessary; repetitive inspections of certain parts for damage and wear, and rework of parts; and electrical bonding checks of certain couplings. This proposed AD would also require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. For certain airplanes, this proposed AD would allow a modification that would terminate the repetitive inspections. The FAA is proposing this AD to address the unsafe condition on these products.

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.
