Federal Aviation Administration April 26, 2021 – Federal Register Recent Federal Regulation Documents

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.

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.

This rule establishes, amends, suspends, or removes Standard Instrument Approach Procedures (SIAPS) and associated Takeoff Minimums and Obstacle Departure procedures (ODPs) 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 safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A318 series airplanes; Model A319-111, A319-112, A319- 113, A319-114, A319-115, A319-131, A319-132, and A319-133 airplanes; Model A320-211, A320-212, A320-214, A320-216, A320-231, A320-232, and A320-233 airplanes; and Model A321-111, A321-112, A321-131, A321-211, A321-212, A321-213, A321-231, and A321-232 airplanes. This AD was prompted by reports that certain oxygen supply solenoid valves are a potential source of increased flow resistance within the flightcrew oxygen system. This AD requires a detailed inspection (flow test) of certain solenoid valves, and replacement if necessary, as specified in European Union Aviation Safety Agency (EASA) ADs, which are incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for PZL Swidnik S.A. (PZL) Model W-3A helicopters. This AD requires repetitive inspections of a certain part-numbered stainless steel cable (cable) installed on a certain part-numbered hoist assembly, and depending on those inspection results, removing certain parts from service and reporting the results. This AD also prohibits installing the affected part unless it is inspected per the AD requirements. This AD was prompted by wear of and damage to the cable near the swaged terminal due to movement of the hook assembly. The actions of this AD are intended to address an unsafe condition on these products.
