Dear fellow glider pilots, FES owners and electric flight enthusiasts, please find our
letter, regarding recent FES incidents.
September 2017
On Sept 6th 2017, the European Aviation Safety Agency (EASA) issued Airworthiness Directive (AD) number
2017-0167-E. The AD identifies the occurrence of fires in the FES battery packs produced by LZ Design.
It is unknown whether the fires are a result of battery internal issues, the specific installations in the affected aircraft,
or external conditions such as mishandling. LZ Design is collaborating with the EASA and also the AAIB from UK with the intent to issue battery
inspection procedures and, if necessary, modification instructions.

The Schempp-Hirth company, who is the world's
leading manufacturer of high performance sailplanes, just publish on
their website, article regarding our visit to their company. We came
to Hahnweide airfield with our new Ventus 2cxa FES, and invited Mr.
Tilo Holighaus and his engineers-pilots to finally perform a few
test flights, as without their support this project could not
happend:
Our impressions were very positive and were thrilled by the FES concept, in all respects. A convincing
system!
...and with immediate effect we will be
offering the production of more such sailplanes: the Ventus-2cxa
equipped with LZ DESIGN’s FES propulsion system!
