Petition for Exemption; Summary of Petition Received; Embry Riddle Aeronautical University
This notice contains a summary of a petition seeking relief from specified requirements of Federal Aviation Regulations. The purpose of this notice is to improve the public's awareness of, and participation in, the FAA's exemption process. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of the petition or its final disposition.
Airworthiness Directives; Leonardo S.p.a. Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for certain Leonardo S.p.a. (Leonardo) Model AW189 helicopters. This proposed AD would require various repetitive inspections of the main rotor (MR) damper. This proposed AD is prompted by reports of in- service MR damper failures and the development of an improved MR damper. This condition, if not corrected, could lead to loss of the lead-lag damping function of the MR blade, possibly resulting in damage to adjacent critical rotor components and subsequent loss control of the helicopter. The actions of this proposed AD are intended to address the unsafe condition on these products.
Airworthiness Directives; Rockwell Collins, Inc. Flight Management Systems
The FAA is adopting a new airworthiness directive (AD) for certain Rockwell Collins, Inc. (Rockwell Collins) flight management systems (FMS) installed on airplanes. This AD was prompted by reports of the flight management computer (FMC) software issuing incorrect turn commands when the altitude climb field is edited or the temperature compensation is activated on the FMS control display unit. This AD requires disabling the automatic temperature compensation feature of the FMS through the configuration strapping units (CSU) and revising the airplane flight manual (AFM) Limitations section. 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 adopting a new airworthiness directive (AD) for certain De Havilland Aircraft of Canada Limited Model DHC-8-400 series airplanes. This AD was prompted by a report that certain elevator power control unit (PCU) arm fittings have nonconforming fillet radii. This AD requires an inspection for affected elevator PCU assemblies, inspections of affected elevator PCU arm fittings for nonconforming fillet radii and cracks, replacement if necessary, and re- identification of the affected elevator PCU assemblies. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. This AD was prompted by a report of vibrations around the 12Hz frequency due to the specific helicopter configuration. This AD requires removing the removable parts of the dual hoist installation or removing the de-icing system. This AD also allows, for certain helicopters, revising the Rotorcraft Flight Manual (RFM) for your helicopter and installing a placard as an optional method of compliance. 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) 2020-03- 12, which applied to all Airbus SAS Model A350-941 and -1041 airplanes. AD 2020-03-12 required revising the existing airplane flight manual (AFM) to define a liquid-prohibited zone in the flight deck and provide procedures following liquid spillage on the center pedestal. This AD continues to require revising the existing AFM, and also requires installing a removable integrated control panel (ICP) cover in the flight deck and further revising the AFM to include instructions for ICP cover use, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by the FAA's determination that a removable integrated control panel (ICP) cover must be installed to prevent damage from spillage and that the existing AFM must be revised. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Fokker Services B.V. Airplanes
The FAA is superseding Airworthiness directive (AD) 2017-06-06 and AD 2019-12-10, which applied to all Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes. Those ADs required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate additional new or more restrictive airworthiness limitations; as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The FAA is issuing this AD to address the unsafe condition on these products.
