Federal Aviation Administration March 9, 2022 – Federal Register Recent Federal Regulation Documents

The FAA is superseding Airworthiness Directive (AD) 2020-12-08 for all Embraer S.A. Model EMB-505 airplanes. AD 2020-12-08 required inspections of the mass-balance weights of the elevators, ailerons, and rudder (flight control surfaces) and their attachment parts, and corrective actions if necessary, and revising the airworthiness limitation section (ALS) of the maintenance manual or instructions for continued airworthiness to incorporate new airworthiness limitations. This AD retains the actions required by AD 2020-12-08 and requires, for certain airplanes, cleaning and weighing certain mass-balances and installation or replacement, as applicable; and for certain other mass- balances for certain airplanes, replacement of those mass-balances. This AD was prompted by a determination that new applicable airplane serial numbers and new criteria for the replacement of affected parts are necessary. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all GROB Aircraft SE (type certificate previously held by GROB Aircraft AG) (GROB) Model G 115EG airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as in-flight detachment of a rudder actuator hinge bracket. This AD requires repairing the support structure at the attachment to the attachment bolts on certain flight control surfaces, inspecting the support structure at the attachment bolts of all flight control surfaces, and taking corrective actions if discrepancies are detected. The FAA is issuing this AD to address the unsafe condition on these products.

These amended special conditions are issued for non- rechargeable lithium-ion battery installations on the Dassault Aviation (Dassault) Model Falcon 6X airplane. Non-rechargeable lithium-ion batteries are a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport-category airplanes. 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.
