Amendment of Class E Airspace; Madera, CA
This action proposes to modify the Class E airspace extending upward from 700 feet above the surface at Madera Municipal Airport, Madera, CA, eliminate references to the Clovis and Friant Very High Frequency Omni-Directional Range/Tactical Air Navigation Aids (VORTAC), and update the airports geographic coordinates to match the FAA's current aeronautical database. In addition, this action would update the airspace lateral dimensions to meet current requirements by removing 4.4 miles of airspace extending to the southeast, adding 0.4 miles to the radius around the Airport Reference Point and adding a portion that extends 1 mile either side of 316[deg] bearing from the 4.4 mile radius to 1.5 miles northwest. This action would support the operation of Instrument Flight Rules (IFR) under standard instrument approach and departure procedures in the National Airspace System.
Airworthiness Directives; Viking Air Limited (Type Certificate Previously Held by Bombardier Inc.; de Havilland, Inc.) Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Viking Air Limited (Viking) Models DHC-6-1, DHC-6-100, DHC-6-200, DHC- 6-300, and DHC-6-400 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 describes the unsafe condition as occurrences of excessive wear of elevator cables at pulley location station (STA) 270.3. The FAA is issuing this AD to require actions to address the unsafe condition on these products.
Streamlined Launch and Reentry Licensing Requirements; Extension of Comment Period
This action extends the comment period for an NPRM that was published on April 15, 2019. In that document, the FAA proposed to streamline and increase the flexibility in the FAA's commercial space launch and reentry regulations. This action would consolidate and revise multiple regulatory parts and apply a single set of licensing and safety regulations across several types of operations and vehicles. The FAA is extending the comment period closing date to allow commenters time to adequately analyze the proposed rule and prepare response.
Airworthiness Directives; Pratt & Whitney Turbofan Engines
The FAA proposes to adopt a new airworthiness directive (AD) for all Pratt & Whitney (PW) PW1519G, PW1521G, PW1521GA, PW1524G, PW1525G, PW1521G-3, PW1524G-3, PW1525G-3, PW1919G, PW1921G, PW1922G, PW1923G, and PW1923G-A model turbofan engines. This proposed AD was prompted by corrosion found on the high-pressure compressor (HPC) front hub, which could result in certain HPC front hubs cracking before reaching their published life limit. This proposed AD would require revisions to the Airworthiness Limitations Section (ALS) of the manufacturer's Instructions for Continued Airworthiness (ICA) and air carrier's approved Continued Airworthiness Maintenance Programs (CAMP) to incorporate new or more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products.
