FAA Targets Phantom Fires in Airbus Choppers with Gear Swap
Published Date: 4/25/2025
Proposed Rule
Summary
If you fly Airbus Helicopters AS 365 N3, EC 155B, or EC155B1 models, listen up! The FAA wants to fix false engine fire warnings by replacing certain fire detectors and stopping the use of the faulty ones. This keeps everyone safer and avoids scary false alarms—plus, it might cost some bucks and needs to happen soon.
Analyzed Economic Effects
2 provisions identified: 0 benefits, 0 costs, 2 mixed.
Required replacement of faulty detectors
The FAA proposes a rule that would require replacing affected engine fire detectors on Airbus Helicopters Model AS 365 N3, EC 155B, and EC155B1 helicopters. The change is meant to stop false engine fire warnings by removing the faulty detectors identified in the referenced EASA airworthiness directive.
Ban on installing affected detectors or engines
The FAA proposes to prohibit installing an affected engine fire detector, or installing an engine that contains an affected engine fire detector, on Airbus Helicopters Model AS 365 N3, EC 155B, and EC155B1 helicopters. The prohibition follows the actions specified in the incorporated EASA airworthiness directive.

2026-10781 — Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Engines
The FAA is hitting pause on a rule that would have made Rolls-Royce Deutschland RB211 Trent engines replace certain low-pressure compressor blades because more blades might be affected than first thought. This means owners and operators of these engines won’t have to act just yet while the FAA digs deeper. Keep an eye out—new rules could pop up once the FAA finishes its review, possibly affecting maintenance schedules and costs.
2026-10801 — Airworthiness Directives; Airbus SAS Airplanes
The FAA is making a new rule for certain Airbus A318, A319, A320, and A321 airplanes because some bolts in seat rails have been breaking. Airlines must swap out nylon bushes for stronger bronze ones and can’t use the old parts anymore. This fix starts July 6, 2026, keeping passengers safer without breaking the bank.
2026-10800 — Airworthiness Directives; Airbus SAS Airplanes
The FAA is rolling out new safety rules for many Airbus A319, A320, and A321 airplanes because extra weight from rudder repainting or repairs might cause stability problems. Airlines must check for airframe vibrations after any vibration event, report what they find, and fix issues if needed. These rules kick in on June 15, 2026, and could mean some extra work and costs for operators to keep flights safe.
2026-10806 — Airworthiness Directives; Goodrich Cabin Attendant Seats
