New rescue helicopter was near the accident – New Technology

       

According to a feature broadcast by SVT’s Mission Review tomorrow night, four out of seven of the Swedish Maritime Administration’s new Augusta Westland 139 helicopters do not have functioning deicing systems. This despite the fact that the manufacturer began selling the system six years ago.

And according to a report from the Swedish Accident Investigation Board has long been specific problems around the tail rotor de-icing system – especially around the slip rings which feeds the rotor blades with electricity so that they warm up. An incident could also have occurred when a slip ring actually came off during a training flight in 2014.

Mowgli Halléhn, ​​head of the Maritime Administration’s helicopter unit, says that there have been quality problems surrounding the de-icing system, since the delivery of the helicopters.

– It is now functioning Fips (Full Ice Protection System) in four of the seven helicopters, he said.

So this means icing is not currently working on three of the helicopters.

However, earlier this year a problem, it was just the four of them had problems, he confirms.

De-icing is important to have when the helicopters flying over water or in clouds with icing, which is common in winter.

How is the flight ability of the problems?

– If there is ice formation in clouds can affect our ability to fly in the clouds. But not so long ago managed than our rescue helicopters, which had a partially deactivated anti-icing system, find a crashed plane in the woods in a plane crash in Västerås and it was the only helicopter that could make a difference when despite the weather, says Mowgli Halléhn.

Technology problems for both the cabling and the slip ring system, which feeds electricity to the main and tail rotors.

to a slip ring came off in 2014 was, according Mowgli Halléhn, ​​quality deficiencies in production at Moog. Regarding the wiring interact Moog and Augusta to achieve better results.

What have you got for information from the manufacturer?

– Augusta is now gradually with quality improvements. But when you’re here with a version that is up to standard, I can not answer, say Mowgli Halléhn.

– I call it teething problems that we are drawn to. De-icing systems on helicopters is not something that has existed for ages.
