Norseman Accident 1978
It was a C55 or A55 Baron on charter from Perth or Jandakot.
Accident happened at night - about 8-9pm, or maybe even 11-12, I think. I think that the pilot had been waiting there patiently for some time, and was anxious to get off back to Perth.
Don't qoute me on this, but, I think the primary cause was failure to remove a control lock pin which had none of the usual wires and red PVC 'locks' over the engine power quadrant, ie, it was more or less a 2 inch hard to see stub thru the yoke.
Not the first time that an aircraft has headed off with a lock still in place, and some of the problem was that the pin had been highly modified, having no warning ribbons, guards etc. During the 60's, a flying instructor in Port Moresby actually got a 182 off the ground and flew a circuit with one of these 'locks' still in place. He was highly praised for his presence of mind in using the trim as primary - but had his ticket suspended 10 secs later!!
happy days
