Airworthiness Directives; Bombardier, Inc., Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-100-1A10 airplanes. This AD was prompted by the discovery of a single-point failure within the left- hand and right-hand heater current monitor (HCM) units. This AD requires installing a monitor circuit comprising relays external to the HCM units. This AD also requires revising the normal and non-normal procedure sections of the existing airplane flight manual (AFM) to add new procedures associated with revised crew alerting system (CAS) messages. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Austro Engine GmbH Engines
The FAA is adopting a new airworthiness directive (AD) for certain Austro Engine GmbH (Austro) Model E4 and E4P engines. This AD was prompted by reports of engine failures and an investigation where cracks were discovered on the pistons. This AD requires repetitive borescope inspections (BSIs) for cracks on the pistons, and, if necessary, removal from service and replacement of the piston, and a fuel sample analysis for water contamination and, if contamination is found, replacement of the high-pressure pump (HPP), injectors, and fuel rails. The FAA is issuing this AD to address the unsafe condition on these products.
Notice of Cancellation of Environmental Impact Statement for the West Virginia International Yeager Airport, Charleston, West Virginia
The Federal Aviation Administration (FAA) announces that it has discontinued preparation of an Environmental Impact Statement (EIS) for the proposed Airfield, Safety, and Terminal Improvement Project at West Virginia International Yeager Airport (CRW) in Charleston, West Virginia. The FAA's discontinued preparation of the EIS is based on the need for additional planning studies to support the proposed development following changes to operations at CRW. The FAA originally placed the EIS on pause on March 27, 2024 and is now cancelling the EIS due to the additional time needed to conduct the necessary studies.
