I made an offer to buy the C-47 and I spent a few hours going over it , I believe it would have been airworthy in 2001/2002 but in mid 2008 it needed engines and props overhauled, ailerons and elevators recovered and a couple of patches of corrosion patched up , and that was what was visible.
The 2 FASI Daks are not looking too flash either , one is now a basket case and the other is borderline. I think these are the last 2 C-47s in Indo ?
I looked at the DGCA records and there was once 175 C-47s on the indonesian register and 4 DC-6s !
