Airworthiness Directives; Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes
Document Number: 2021-08622
Type: Proposed Rule
Date: 2021-04-26
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD- 500-1A11 airplanes. This proposed AD was prompted by a report that following an in-service engine shutdown during taxi, water was found to be dripping into the forward avionics bay; the water caused a short circuit and tripped a circuit breaker. This proposed AD would require replacing the forward galley slotted drain covers with solid blanking plates and modifying the associated drain tubing to block water. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes
Document Number: 2021-08620
Type: Proposed Rule
Date: 2021-04-26
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD- 500-1A11 airplanes. This proposed AD was prompted by a design review that identified rib 0 of the center wing box (CWB) as an area where a single failure of a clamshell type refuel/defuel line coupling could lead to the accumulation of dangerous levels of electrostatic charges within the fuel tank. This proposed AD would require replacing the clamshell type refuel/defuel line coupling in the CWB at rib 0 with a threaded type fuel coupling, and installing an additional support bracket and clamp in the CWB at rib 0, as specified in a Transport Canada Civil Aviation (TCCA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Notice of Intent To Rule on Request for Change in Land Use From Aeronautical to Non Aeronautical for 16.2 Acres of Land at Pittsfield Municipal Airport, Pittsfield, MA
Document Number: 2021-08594
Type: Notice
Date: 2021-04-26
Agency: Federal Aviation Administration, Department of Transportation
Notice is being given that the FAA is considering a request from the Town of Pittsfield, MA to change 16.2 acres of land from aeronautical to non-aeronautical use for non-aeronautical revenue generation at Pittsfield Municipal Airport, Pittsfield, MA. The airport has two projects. The fire project is the installation of a solar farm and the second is a municipal water tank that will service the airport. The solar facility will be built on three on airport sites, totaling 15.5 acres, and will produce 6 mW of energy. The power produced will go into the electrical grid, however, the airport will have a long term land lease with the solar utility, generating a long term revenue stream for the airport. The lease revenue will be placed in the airport's operating and maintenance fund. The municipal water tank will serve the community as well as the airport, significantly enhancing the existing airport water system and serve future development on the airport as well. The tank and access road requires approximately .73 acres and will not interfere with future development of the airport.
Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments
Document Number: 2021-08591
Type: Rule
Date: 2021-04-26
Agency: Federal Aviation Administration, Department of Transportation
This rule amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide for the safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
