FAA Proposes Battery Alerts to Stop Helicopter Power Surprises in Flight
Published Date: 2/6/2025
Proposed Rule
Summary
If you fly a Leonardo A119 or AW119 MKII helicopter, listen up! The FAA wants to make sure your helicopter’s battery doesn’t suddenly lose power by adding a new battery discharge detector and updating the flight manual. These changes help keep you safe and need to happen soon to avoid any electrical surprises in the sky.
Analyzed Economic Effects
2 provisions identified: 1 benefits, 0 costs, 1 mixed.
Battery Detector Installation Required
The FAA proposes a rule that would require installing a battery discharge detector on all Leonardo S.p.a. Model A119 and AW119 MKII helicopters. This action follows a report of a starter-generator electrical failure from a ruptured drive shaft that caused a partial loss of battery power, and is meant to prevent sudden loss of battery power in flight.
Flight Manual Updated for Safety
The FAA proposes that operators of Leonardo S.p.a. Model A119 and AW119 MKII helicopters revise the Rotorcraft Flight Manual (RFM) as specified in the referenced EASA AD. The manual change is intended to address the unsafe condition related to starter-generator failure and partial battery-power loss.

2026-13440, Enabling Supersonic Overland Flight
The FAA wants to let supersonic planes fly over land again by updating old rules that banned them because of loud sonic booms. Thanks to new tech that keeps booms quiet, this change will open the door for faster, cooler flights across the U.S., helping America lead the world in supersonic travel. People and companies interested in supersonic flight should share their thoughts by August 17, 2026.
2026-13126, Designation-Restrict the Operation of Unmanned Aircraft in Close Proximity to a Fixed Site Facility; Extension of Comment Period
The FAA is giving more time—until August 5, 2026—for people to share their thoughts on new rules that would limit drone flights near important fixed sites like power plants or airports. This affects drone operators and facility owners who want to keep the skies safe and secure. No new costs yet, just extra time to weigh in and help shape the rules.
2026-08943, Designation-Restrict the Operation of Unmanned Aircraft in Close Proximity to a Fixed Site Facility
The FAA is proposing new rules to keep drones away from certain important fixed sites like power plants or airports to keep everyone safe and secure. If you own or operate one of these sites, you can request a drone flight restriction zone to protect your property and people nearby. Comments are open until July 6, 2026, and these changes could affect drone pilots and site operators, but no big costs are expected.
2026-16750, Establishment of Class E Airspace; DeKalb, IL
This action proposes to establish Class E airspace at Northwestern Memorial Healthcare Heliport, DeKalb, IL. The FAA is proposing this action to support new instrument procedures and instrument flight rule (IFR) operations.
2026-16754, Agency Information Collection Activities: Requests for Comments; Clearance for Renewal of Information Collection: Privacy International Civil Aviation Organization (ICAO) Address
In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval for an information collection renewal. The collection involves an aircraft operator's request for a privacy ICAO address through a web-based application process. The information to be collected is necessary to qualify for the authorized use of the privacy ICAO address services and for monitoring to support continued airworthiness and enforcement activities.
2026-16705, Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Engines
The FAA proposes to adopt a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent XWB-75, XWB-79, XWB-79B, and XWB-84 engines. This proposed AD was prompted by reports of differential oil pressure measurements that were lower than expected on in-service engines. This proposed AD would require modification of the engine with an improved front bearing housing oil feed tube assembly. This proposed AD would also prohibit the installation of an affected front bearing housing oil feed tube assembly on any engine. The FAA is proposing this AD to address the unsafe condition on these products.
