Tekin and Oksapmin are challenging at the best of times, however this time of the year with the Northwesterly wind flows the turbulence can be horrendous in the area out there.
I’ve been in a Twin Otter going into Oksapmin where I had absolutely no control of the aeroplane due to the turbulence, only solution was to take my hands of the controls and let the aeroplane fly itself, which it did a lot better than me. Once things settled down I was able to resume control.
The challengers of bush flying in the PNG highlands, sadly which isn’t recognised much these days as much as it was years ago.
I know most of the pilots operating up there now are pretty experienced and haven’t been operating in the area for 5 minutes, hence I believe it would be fair to assume that the accident was attributed to bad luck.
