Introduction
In a significant development that underscores safety and environmental responsibility in aviation, Avcon Industries, Inc., along with its affiliate Butler Avionics Inc., has successfully obtained the FAA Supplemental Type Certificate (STC) for the installation of non-halon fire extinguishers in various Learjet models. This breakthrough marks a pivotal shift away from halon, a chemical notably harmful to the ozone layer, toward more ecologically sound alternatives.
Details of the Approval
On August 21, 2025, it was announced that Avcon Industries had received FAA STC No. ST12087CH, which authorizes the replacement of existing halon fire extinguishers with Halotron BrX-filled units in Learjet models 24, 25, 29, 31, 31A, 35, 36, 35A (C-21A), 36A, 40, 45, 55, 55B, 55C, 60, 60XR, 70, and 75. This new installation is designed to meet compliance requirements not only from FAA but also in anticipation of European Union Aviation Safety Agency (EASA) validations. The Halotron BrX fire extinguishers offer an effective solution while being size-equivalent replacements, thereby ensuring ease of installation without compromising the functionality or design of the aircraft.
Environmental Impact and Regulatory Movement
Halon has been classified as an ozone-depleting substance and its production has been banned in the EU since 1994. While there have been allowances for critical uses, including aerospace applications, regulations under the Montreal Protocol necessitate that halon fire extinguishers in airplane cabins and crew compartments be replaced by December 31, 2025. Avcon’s proactive move to offer a suitable alternative aligns with EASA's mandate, thereby paving the way for a more sustainable aviation industry. Patrick Hupp, Avionics Manager at Avcon, expressed the company's commitment to comply with these stringent safety standards while supporting legacy aircraft with effective solutions.
Installation and Future Plans
The newly approved extinguishers are engineered for straightforward installation at the same locations as the original units, while also providing additional mounting options for older Learjet models. Avcon is currently applying for EASA validation of this STC approval, and further plans include expanding the list of STC-approved models to enhance its offerings.
