Airworthiness Criteria: Special Class Airworthiness Criteria for the Joby Aero, Inc. Model JAS4-1 Powered-Lift
The FAA announces the availability of, and requests comments on, the proposed airworthiness criteria for the Joby Aero, Inc. (Joby) Model JAS4-1 powered-lift. This document proposes airworthiness criteria the FAA finds to be appropriate and applicable for the powered-lift design.
Airworthiness Directives; Airbus SAS Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A350-1041 airplanes. This AD was prompted by a potential interference between the ram air turbine (RAT) blade tip and the belly fairing (BF) RAT inboard door. This AD requires replacing the BF inboard RAT door and BF adjacent panels, and prohibits the installation of affected parts, as specified in a European Union Aviation Safety Agency (EASA), which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; De Havilland Aircraft of Canada Limited (Type Certificate Previously Held by Bombardier, Inc.) Airplanes
The FAA is superseding Airworthiness Directive (AD) 2020-04- 20, which applied to certain De Havilland Aircraft of Canada Limited Model DHC-8-400 series airplanes. AD 2020-04-20 required 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. AD 2020-04-20 also required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. For certain airplanes, AD 2020-04-20 allowed a modification that terminates the repetitive inspections. This AD continues to require the actions in AD 2020-04-20, revises the applicability by adding airplanes, and requires, for certain airplanes, the previously optional rework and retrofit of certain parts of the fuel system. Doing the rework and retrofit terminates the retained initial and repetitive inspections in this AD. This 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, and by a determination that a more robust lightning ignition protection design is necessary. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 and A350-1041 airplanes. This AD was prompted by a determination that in the event of rapid decompression at a specific location of the airplane, possible deflections of the passenger floor cross beams may result in wiring damages, leading to potential system losses. This AD requires amending the operator's existing airplane flight manual (AFM) to update the landing performance database, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
The FAA is superseding Airworthiness Directive (AD) 2021-06- 07, which applied to certain Airbus SAS Model A330-200 series and A330- 300 series airplanes. AD 2021-06-07 required repetitive detailed inspections of the courier area oxygen system (CAOS) and replacement of affected parts if necessary. Since the FAA issued AD 2021-06-07, improved flexible oxygen hoses have been developed. This AD continues to require repetitive detailed inspections of the CAOS and replacement of affected parts if necessary. This AD also requires replacing each affected part with an improved serviceable part, which is terminating action for the repetitive inspections. The FAA is issuing this AD to address the unsafe condition on these products.
