Britten-Norman introduces Unleaded Fuel Modification for piston engine Islanders

Britten-Norman is taking the next step on its journey towards sustainable aviation with the introduction of the Unleaded Fuel Modification for its BN2B-26 piston engine (Lycoming O-540-E4C5) Islander aircraft.

In addition to reducing their environmental impact, operators of Islander aircraft who switch to unleaded fuels can potentially enjoy several benefits. These include cost savings on refuelling, reduced maintenance expenses, access to a wider range of fuel options, extended servicing intervals and enhanced safety through the use of unleaded fuels.
 
The decision by the US Federal Aviation Administration (FAA) to phase out leaded AVGAS has further underlined the importance of transitioning to unleaded fuels.

The certification of these new fuel types for the Britten-Norman Islander through the introduction of the Unleaded Fuel Modification opens the door to further possibilities for novel and environmentally friendly fuel types in the future.
 
Mark Shipp, Technical Director and Head of Design at Britten-Norman, commented: “Britten-Norman is committed to delivering a sustainable future for aviation through our Green Futures initiative. This development is an important milestone for the hundreds of Islander operators who will be able to reduce their emissions through the introduction of unleaded fuels.”
