BEST Aircraft Equipment, Maintenance & Mfrs in Pelton NSW 2325

I left VH-NNT with Eagle Aircraft Maintenance in Pockolbin in Feb. 2020 for a annual or 100 hourly service. As well as the service , I asked them to look at three other faults : 1) The undercarriage extending during flight. 2) HSI was reading incorrectly. 3) Storm Scope was not operational. After spending $7,000 on HSI it was decided that the problem lay in a part in the aircraft wing. After several attempts and some money spent, the undercarriage still extends during flight. The cost of the service and the above repairs so far this year is $20,000, it is now November 21st, 2020 and the aircraft is not and has not been airworthy for the last nine months. I have taken the aircraft from them and will have the undercarriage fault repaired at another facility. My name is John Cross, I can be reached on [personal phone number removed]
