Super Puma Tips Over At Boundary Bay


Recommended Posts

 

I'm curious though, how many pilots in the S64 for a ground run? We only needed one for the 61N and 61L.

The crane is a two pilot ship even for ground runs.....too many things can go wrong especially after maintenance...!!!

The fine fellows that are authorized at Cougar go through an intense training regime at Flight Safety International in the Level D simulator. There is very little that they don't know how to respond to after that. Being used to the night shift, they will very likely be safer at the controls than some poor sap of a driver that got a phone call at 23:30 to come in for 0100 when he thought he had the next day off duty.

 

Been there and have the T-shirt.

 

Interesting---Thanks

For all the Monday morning quarterbacks...

 

"Forward servo found in fully extended position with flight controls neutral or flat pitch. This would cause uncommanded right and rear roll moment."

 

Good thing this happened on the ground.

 

Hence the very good reason for ground runs with the rotor turning.

The Chinook is also a 2-pilot (and at least one flight engineer) machine, including ground runs. There are a number of primary and major secondary controls that either couldn't be reached by a single pilot, or would require two pilots to react sufficiently quickly to deal with an emergency.

 

Glad that there were no injuries sustained by the MTP!

I'm not endorsed on the Puma at all, but this makes me wonder if this is a post accident indication.

I am pretty certain that the flight controls are mechanical thru this aircraft as many are, so to be maintaining flat pitch/neutral, the servo's would show the same unless they were damaged in the rollover. A servo pilot valve going into a runaway condition would still move the controls unless it was uncoupled (ie from a maintenance action or a failure)

I'd be curious to know the result of that finding...it just doesn't sit well with me on a mechanical level. doesn't seem right.
