Halon has long been the gold standard in aviation fire suppression. But it’s also a major ozone-depleting chemical, and regulators are now phasing it out globally.

By December 31, 2025, all portable Halon fire extinguishers must be replaced on aircraft operated under EASA jurisdiction (and globally for ICAO compliance).

Key mandates:

  • No new aircraft with Halon bottles since 2019
  • Retrofit deadline: Dec 31, 2025 for all existing fleets
  • Applies to: handheld/portable extinguishers in cockpits, cabins, and crew areas

What’s Charging?

Replacing Halon is not a drop-in swap. Replacement agents are:

  • Heavier
  • Require different brackets or locations
  • Impact CG/balance (especially on smaller aircraft)
  • Must be STC-certified or approved under minor change (via DOA)

Halon-Free Agents in Aviation Use

Here’s what’s currently available and certified:

AgentDescriptionProsCons
Halotron BrXClean agent (2-BTP), FAA/EASA certifiedLow residue, low toxicityHeavier than Halon, larger volume
PhostrExEngine bay systems, FAA certifiedExtremely fast, low volumeCorrosive to metals, niche use
Aerosol SystemsNon-pressurized condensed aerosolsCompact, efficientNot yet mainstream

Some aircraft OEMs already offer pre-certified upgrade kits—check with your design organisation or STC holder.

YOUR 5-STEP COMPLIANCE CHECKLIST

  1. Inventory your fleet – Identify every aircraft with Halon bottles.
  2. Engage your DOA or CAMO – Determine modification path (STC vs minor change).
  3. Procure certified extinguishers – Choose a Halon-free agent and source with brackets.
  4. Plan installations – Coordinate scheduled maintenance to avoid downtime.
  5. Recycle responsibly – Halon is hazardous waste; dispose of cylinders through licensed reclaimers.

With less than six months to go, expect backlogs in extinguisher supply, design approvals, and bracket kits if you wait.

THE COMBINED STRATEGY: BE SMART, BE READY

  • Transition to Halon-free fire suppression before you hit regulatory or insurance deadlines.

This is more than a compliance push—it’s a chance to boost sustainability, reduce downtime, and enhance fleet safety.
