Federal Aviation Administration July 2019 – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for certain Saab AB, Saab Aeronautics Model SAAB 2000 airplanes. This proposed AD was prompted by reports of loose and irregular fasteners at the forward end of the nacelle upper longeron, where the bulkhead frame and struts are attached to the engine mounting structure (EMS). This proposed AD would require modification of the EMS and structural attachments. The FAA is proposing this AD to address the unsafe condition on these products.

These special conditions are issued for the Dassault Aviation (Dassault) Model Falcon 7X airplane. This airplane will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport-category airplanes. This design feature is the installation of large, non- structural glass panels in the passenger compartment. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

The FAA proposes to supersede Airworthiness Directive (AD) 2019-05-09, which applies to certain Airbus SAS Model A320-251N and - 271N airplanes, and Model A321-253N airplanes. AD 2019-05-09 requires repetitive detailed inspections of certain electrical harnesses for discrepancies and corrective actions, if necessary. AD 2019-05-09 also provides an optional terminating modification for the repetitive detailed inspections. Since we issued AD 2019-05-09, the FAA has determined that it is necessary to require the terminating modification. This proposed AD would retain the actions of AD 2019-05- 09 and add a requirement for a terminating modification for the repetitive inspections, as specified in an European Aviation Safety Agency (EASA) AD, which will be incorporated by reference. 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 all Airbus SAS Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). This proposed AD was prompted by a determination 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 supersede Airworthiness Directive (AD) 2017-06-08, which applies to certain Embraer S.A. Model ERJ 170-100 LR, -100 STD, -100 SE, and -100 SU airplanes; and Model ERJ 170-200 LR, - 200 SU, and -200 STD airplanes. AD 2017-06-08 requires revising the existing maintenance or inspection program, as applicable, to incorporate more restrictive airworthiness limitations. Since the FAA issued AD 2017-06-08, the agency 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. This proposed AD would also add airplanes to the applicability. The FAA is proposing this AD to address the unsafe condition on these products.
