But if anyone of you do the research you will find that it is fact that the sim was still operating with inoperative rudder pedals for up to 4-6 weeks. ATR were still allowing companies to use it in this condition
Yes the SIM in Singapore operating for about 2 weeks without rudder pedals on the Captains side not 4-6 like you say. You are correct in saying many companies continued to train and check their crews in it, all apart from the Kiwi and Ozzy companies that refused. It is completely at the airlines and TRE/TRIs descretion if they want to continue training in a faulty product. Read into that what you will!
