I do not doubt that "restricted" has to do with accidents, but when a private company buys a helicopter to do commercial bussiness and goes for restricted actually means in some way the attitude about spending money for the job. Most bogus parts around the world are mounted in restricted aicrafts. Anyway my point in the previous post was that the company that had the accident already has a sad record on fatal accidents and BTW the crash took place when the TAILBOOM COME APPART from the rest of the helicopter, there was no hitting any power line or any other thing. The flight plan was filled with 4 POB and actually there were 8 bodies in the crash ????? The work had been already done. Sorry have to goĦĦĦĦ
