The article in the current edition of
Defence Helicopter includes the following comment:
At the [ILA] airshow, [EC CEO] Bertling said it was not actually the chafing of the physical wiring on the aircraft that is the issue, but the Nomex wire sleeving, which protects the wiring while the aircraft is being built. Spanish and French authorities accept some chafing of the sleeving, but the German authorities do not.
