The Ozone Enzo 2 is certified EN D, with or without its extra long
trailing edge, Ozone said on Saturday – and human error was to blame for the
longer trailing edge.

Speaking from his home in England Ozone’s boss Mike Cavanagh said the longer
trailing edge on the Enzo 2 was the result of a mistake.

He explained that the original glider that was tested and certified had several
“pinches” in the trailing edge.

Pinches are sewn in to a glider during development to allow test pilots to fly
the wing with slightly different configurations. Like putting knots in lines to
alter the trim of a glider they help test pilots hone the wing.

However, in the case of the Enzo 2 the final pinches were not carried through
into the production model. Around 100 Enzo 2s have been made.

The glider tested on Saturday morning in Switzerland was the original test
glider with the pinches taken out to lengthen the trailing edge.

Mike said: “All Enzo 2 wings will have a longer trailing edge because we did not
put the pinches in [to the production model]. It’s a mistake.”

He added: “It’s not something we would measure as it is not an EN requirement,
and it wouldn’t have been a PWC requirement either – it still isn’t.”
