I would like to know how it was possible to mix military parts with the approved civil ship and parts??? The mil parts not having a BO105 civ partnumber and no civ ticket. Over the last 20 years it was impossible to use one single screw from the mil ships on civ registered. Germany phased out so many BOs from mil service. To get very cheap. But EC prohibited strictly the use of ex-mil ships and any parts. Very strictly!
And if it was no part in the certification process aerobatics couldn`t be approved on my sight for a civil registered helicopter according to the present rules. But with the power and money of REDBULL...
