The Bundeswehr temporarily suspended flight operations with all 53 Tiger Tiger helicopters. The army announced in a press release: The Bundeswehr had "through a message from the industry gained knowledge that certain bolts that are installed in the attack helicopter Tiger , could have a shortcoming," it said. The General Flugbetrieb Heer had therefore ordered to temporarily suspend flight operations with the attack helicopter Tiger. Because: "Safety is a top priority for the Bundeswehr."
Affected, according to the Bundeswehr, the Tiger helicopters in the Kampfhubschrauberregiment 36 in Fritzlar and the German-French Army Aviation Training Center in Le Luc in France. Since currently no Tiger helicopters are in use abroad, only routine flights have been canceled.
For Thursday a panel of experts is scheduled to clarify the way forward. In any case, all Tiger helicopters would be thoroughly checked before their next launch - defective bolts would be replaced if necessary.
It was also stated that the affected bolts were also installed in the transport helicopter NH90 and in the training helicopter EC135. However, since the bolts are not there "in safety-relevant places", the flight operations could be continued with these helicopters.
According to information from the mirror , the possibly defective bolt is relevant for the control of the rotors. According to the manufacturer Airbus Helicopters, some bolts may have hydrogen embrittlement - then there is a risk that they will break during the flight.
The machines of the type Tiger are the most modern helicopters of the Bundeswehr. Of the 53 helicopters, however, on average only 11.6 were ready last year.
