Rex Saab 340B VH-NRX Update

This afternoon VH-NRX was parked on DOM 5 in among the Corporate Jets, this time with both propellers missing. I would assume that the Port Prop and Drive Shaft have be removed for testing, as
they were possible from the same component batches. It also looks like part of the Port Wing leading edge has been removed, outward of the engine.

Question Rotational direction?

I'm sure the answer is online somewhere, but I prefer the SAMB knowledgebase. Does the Saab 340 have counter-rotating props, or do they both spin clockwise or anti-clockwise? My recollection from the last time I sat in a seat next to a prop was that they both spin clockwise.

I only ask because of the reported trajectory of the prop after the shaft sheared: it is said to have gone up and assumed a horizontal plane like a Frisbee before drifting off in the wind to its final resting place. Missing the fuselage and control surfaces was incredibly lucky, but what would have happened if the prop had come off the left engine? Or are there just too many variables/vectors at work to be able to predict anything?

Half of NRX is in the REX hangar tonight when I went past. Looks like a few people looking at it too.

Preliminary report below.

http://www.atsb.gov.au/publications/...r/ao-2017-032/

A fatigue fracture near a dowel pin bore on the prop mounting flange appears to be responsible.

The report goes on to say there is currently no requirement to inspect dowel pin bores.

Cheers

M

Nothing worse than a fatigue fracture near your flange I've always said......
