Special Conditions: Pro Star Aviation LLC, Bombardier Model CL-600-2B16 Airplanes; Installation of an Infrared Laser Countermeasure System
These special conditions are issued for the Bombardier Model CL-600-2B16 (Bombardier) airplane. This airplane, as modified by Pro Star Aviation LLC (Pro Star Aviation), 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 a system that emits infrared laser energy outside the aircraft as a countermeasure against heat-seeking missiles. 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.
Adoption of the Missile Defense Agency's Final Environmental Impact Statement for Long Range Discrimination Radar (LRDR) Operations, Clear Air Force Station, Alaska (CAFS), and Record of Decision for Federal Aviation Administration Actions To Accommodate Testing and Operation of the LRDR at CAFS Under the Missile Defense Agency's Modified Operational Concept
This notice announces the availability of the FAA's Adoption of the Missile Defense Agency's Final Environmental Impact Statement for Long Range Discrimination Radar (LRDR) Operations, Clear Air Force Station, Alaska (CAFS), and Record of Decision for Federal Aviation Administration Actions to Accommodate Testing and Operation of the LRDR at CAFS under the Missile Defense Agency's Modified Operational Concept (``the Adoption/ROD''). The Adoption/ROD documents: (1) The FAA's adoption of the Missile Defense Agency's (MDA) Environmental Impact Statement (EIS) for Long Range Discrimination Radar (LRDR) Operations, Clear Air Force Station (CAFS), Alaska; and (2) the FAA's decision to establish additional restricted areas to protect aviation from high- intensity radiated fields (HIRF) generated during the LRDR testing and operation, implement temporary flight restrictions (TFR) until the restricted areas are in effect, and make changes to federal airways and instrument flight procedures to accommodate the new restricted areas.
Airworthiness Directives; Leonardo S.p.a. Helicopters
The FAA is superseding Airworthiness Directive (AD) 2020-19-11 for certain Leonardo S.p.a. Model A119 and AW119 MKII helicopters. AD 2020-19-11 required repetitive borescope inspections of the 90-degree tail rotor gearbox (TGB) and depending on the inspection results, removing the TGB from service. This AD was prompted by the determination that additional parts may be susceptible to the unsafe condition. This AD retains the inspection requirements of AD 2020-19-11, and revises the compliance time and applicability. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Leonardo S.p.a. Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for certain Leonardo S.p.a. Model AW189 helicopters. This proposed AD was prompted by a report that a number of fairleads that support the engine combustion chamber D1 drain hose showed evidence of heat damage. This proposed AD would require modifying the helicopter by installing a certain engine combustion chamber D1 drain assembly, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Sikorsky Aircraft Corporation Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for certain Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters. This proposed AD was prompted by a cracked main rotor stationary swashplate assembly (swashplate assembly). This proposed AD would require visually inspecting the swashplate assembly at specified intervals and depending on the results, removing the swashplate assembly from service. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Hélicoptères Guimbal Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for H[eacute]licopt[egrave]res Guimbal (HG) Model Cabri G2 helicopters. This proposed AD was prompted by the determination that certain parts need life limits and certification maintenance requirement (CMR) tasks. This proposed AD would require establishing life limits and CMR tasks for various parts and removing any parts from service that have reached or exceeded their life limits. Depending on the results of the CMR tasks, this proposed AD would require corrective action. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc., Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-100-1A10 airplanes. This proposed AD was prompted by reports of erratic electrical system status on the push button annunciators (PBAs) and the engine instrument and crew alerting system (EICAS). This proposed AD would require revising the existing airplane flight manual (AFM) and applicable corresponding operational procedures to incorporate procedures to be applied during erroneous electrical status indication conditions. The FAA is proposing this AD to address the unsafe condition on these products.
Proposed Amendment of Class C Airspace at Chicago Midway International Airport, IL; Public Meeting
This document announces a fact-finding informal airspace meeting regarding a plan to amend the Class C Airspace at Chicago Midway International Airport, IL. The purpose of the meeting is to solicit aeronautical comments on the proposal's effects on local aviation operations. All comments received during the meeting, and the subsequent comment period, will be considered prior to the issuance of a notice of proposed rulemaking.
Airspace Designations; Incorporation by Reference
This action amends 14 CFR part 71 relating to airspace designations to reflect the approval by the Director of the Federal Register of the incorporation by reference of FAA Order JO 7400.11F Airspace Designations and Reporting Points (the Order). This action also explains the procedures the FAA will use to amend the listings of Class A, B, C, D, and E airspace areas; air traffic service routes; and reporting points incorporated by reference.
