EASA SIB 2022-08: Mitigation of Flight Deck Fires Originating from Lithium Batteries that are not Part of the Aircraft Design

What to do

Large aeroplane operators are recommended to prohibit transporting PEDs, spare batteries, or power banks on the flight deck unless they can be stowed in compartments specifically designated for these items by the design approval holder. Operators should implement relevant service bulletins from type certificate holders and include lithium battery fire scenarios in risk assessments for electronic flight bags (EFBs). There are no specified compliance deadlines as the recommendations are not mandatory.

Summary

EASA Safety Information Bulletin 2022-08 is a safety information bulletin addressing the mitigation of flight deck fires originating from lithium batteries that are not part of the aircraft design, applicable to all large aeroplane operators. It highlights the risks associated with personal electronic devices (PEDs), power banks, and spare lithium batteries carried on the flight deck, which can cause thermal runaway leading to fire, smoke, and explosions. The bulletin references EASA Special Condition SC-G25.1585-01 and other related publications but does not mandate regulatory action.

What changed

EASA SIB 2022-08 introduces awareness and recommendations regarding the fire risks posed by lithium batteries in PEDs and spare batteries on the flight deck of large aeroplanes. It informs operators about ongoing reviews of existing aircraft designs for potential unsafe conditions and encourages implementation of service bulletins and risk assessments related to lithium battery fires. No mandatory airworthiness or safety directives are issued at this time.

Why it matters

This bulletin matters because the increasing presence of lithium battery-powered devices on the flight deck raises the risk of in-flight fires that could jeopardize flight safety and damage critical systems. Operators, maintenance, and compliance teams need to understand these risks to prevent hazardous events and ensure safe stowage and use of such devices. Addressing these risks proactively helps avoid catastrophic occurrences and supports regulatory compliance.
