The fatal crash of a “Tiger”helicopter of the Bundeswehr in the summer of 2017 in Mali to largely be due to a technician error from the manufacturer, Airbus have been triggered. This should have set the main rotor in the wrong. This is to MIRROR information from an investigation report of the German Federal armed forces.

According to the 95-page report from the 7. December, the news agencies Reuters and dpa report, was the incorrect adjustment of the rotor blades is ultimately responsible for ensuring that the helicopter, with two pilots downed at about 135 knots (250 kilometers per hour) at an altitude of about 550 meters, completely unexpectedly to the front, and with nearly 180 knots (333 kilometers per hour) to the ground detent.

The Crew was able to the fall flight is no longer correct

The accident occurred on a flight to a use for the UN. According to the report, the “incorrect leveling” of the rotor head was the main cause for the crash. In consequence, there was a “MIS-setting of the main rotor control system,” that “in the final result of the dumping and destruction of the helicopter”.

Simplifies the incorrect setting had said on the day of the disaster, an extreme flight situation, the Autopilot steered the plane down and then shut off. The Crew was not able to correct the nosedive.

Literally, it says in the report, the main rotor control of the helicopter was already in may 2016, “by the staff of the manufacturer” and, specifically, of three Airbus engineers, the so-called Rigging of the “wrong” set. This is a “direct-acting factor” for the subsequent crash.

According to the research of the German armed forces, the Airbus had not completed-technician of your “specified training” and not “possessed the necessary qualifications for the implementation or acceptance of the adjustment rotor-control work on the main”.

This Work but, according to the Report, “would need to be carried out under the guidance of experienced staff”.

The Crew had no Chance

The Crew, two very experienced pilots of the German armed forces, had, according to the report in the Crash-no Chance. According to the study, they had levers during Autopilot flight, the hands of the Tax. After the completely unexpected tipping but the G-forces were so strong, they can stabilize the helicopter would not have. That you couldn’t do this, evaluate the report as a “not-acting factor”.

On the day in July 2017, two “Tiger had been requested” by the UN for a Mission, because near the village, around 150 kilometres Tabankort, North of Gao battles took place. The crash occurred, however, after about 70 kilometers of flight at 12: 20 PM, local time, long before the flight of two helicopters had reached the target area.

The German army was restricted after the accident, the use of the autopilot for all the “Tiger” is already massive and restrictions for the height and the pace to adopt. Airbus was, in turn, a warning message, according to this, the pilots must also maintain the automated flight both hands on the wheel, to be able to respond at any time.

Bundeswehr gives error

Despite the clear apportioning of blame in the direction of the Airbus, the Bundeswehr acknowledges in the study report their own errors. So technicians need to inspect the helicopter after delivery by the industry were not sufficient for the demanding task trained.

Apparently, the German army had not been checked by the engineer the papers of the later crashed helicopter correctly, knew but the technical method, which was used by Airbus for the rotor setting. In addition, a first message via a flight anomalies had not been taken to the accident helicopter seriously enough. The Bundeswehr experts still come to the judgment that this defect was not directly responsible for the crash.

For the families of the two pilots ends with the report a distressing period of uncertainty. Before the deputies Peter Clement, who currently holds the Post of General aviation safety was informed about the complicated results of his investigations.

If Airbus accepts the clear blame, is unclear. The manufacturer of the “Tiger”, also for other European armies in the field, had been cooperating in the investigation, but was not involved in the evaluation of the results.
