Maybe I'm really anal about my aircraft maintenance, but I think this shows 7 years of neglect more than 7 years of care by "the best helicopter mechanic around here". What do you think? Found the transmission bolts loose and lots of RTV to cover it all up instead of just torque to SIL 0166 recommendations. Under cockpit floor and in engine bay and all skins show major neglect. Took hours to clean and will have to reapply zinc chromate to most panels and to many support tubes. Collective and belt drive not rigged properly. Main rotors never maintained and had bare aluminum exposure for the entire time, thus exfoliation. This is a mess, but won't be when I'm done. Here is link to what I discovered so far.
