Wow, ol' Zouky is NOT going to be happy with that one :P

Channel Nine chopper damaged also.
How does the jet get that far during an engine test?

You could ask Airbus! They've proved it can happen no matter the size or the jet...

Wow. I originally thought 'significant weather event' causing fence to collapse onto the jet and also moving and damaging the chopper.

Did the jet really run through the fence?? If yes, "whoops" is one way of describing it.

Interesting; so the Challenger was doing engine runs? were there chocks under the wheels?

Believe there was a pilot and engineer on board? Can anyone confirm status?

Challenger + Merlin III + Helicopter, + building damage....

Big dent in the pride of Aust, Corp Jets, Where are you Sam?

Terrible place to face failed brakes amongst any emergency. Almost zero room to manoeuvre thanks to greedy developers who have built shopping malls, car yards, offices, right up to the inch of every bloody taxiway, runway, and hangers.

The news report said that it jumped the chocks.

It was just trying to get TF out of Victoria.

Nothings' jumped me lately... sorry to say.:)

Our's said the brakes failed, one thing in evidence is both could could have lead to the obvious result, but if it jumped the chocks why didn't the brakes stop it?

It is not my position to comment on this unfortunate incident.

What I will say that the procedure in a very well disciplined company I worked for was to take the following precautions for any engine ground runs: Park brake applied, chocks in front of each MLG, aircraft pointed towards an “escape route” in case it jumped the chocks, a qualified person in the flightdeck command seat at all times, and, if necessary, a spotter to to keep a general eye on things.

Does the ASIC apply on the other side of the fence? -)

Very Good advice.
The following is a question only to spark debate so that we may learn from the collective knowledge.
I have discussed on many occasions the way to chock an aircraft. I recall reading some advice from Boeing, allegedly as I do not have the reference to hand right now, that the correct way to chock an aircraft (for engine runs) is to place the chocks about an inch in front of the wheels. The reason for this being that if the chock is tight against the wheel the chock becomes a ramp it is quite likely to ride up over the chock but if there is a small gap when the wheel contacts the chock it pushes down into the chock. The assumption being that if the chocks are placed hard into the wheel then the wheel could ride up over the chock.

Discuss, politely and in an mature adult manner please.

Why do people do a run up facing a fence, building or other ac?

dirtyd,

Laziness, coupled with poor safety management skills, lack of SMS training, analysis and risk assessment are the reasons why..

There may be underlying factors. Was the crew on board occupying the control seats qualified to be there, for example a type rated pilot, aircraft engineer certified for engine runs in no flight crew member present. Was the pre-flight, pre-start checklist completed. Braking pressure checked, emergency braking system armed and checked?

Photo's suggest there was a tow bar attached at the time of the incident, so there would have been adequate equipment available to position the aircraft to a more sensible location.

No doubt the Underwriters will be looking very closely at all the factors.

The Main thing is nobody was injured

Not sure about the chocks becoming a ramp, might depend upon the type of chock? I do recall being taught to put the chocks about an inch away from the wheels so you can get the damn things out after refueling!!

If that EGR was above idle why wasn’t it ran at the run up bay?

Golden Rivet, answer - too lazy !

Penultimate182 - you have no idea at all what you are talking about. Millions of dollars of liability to two or possibly three aircraft, as I believe a Merlin III aircraft may be involved. Damage to expensive ground equipment, and damage to surrounding property, buildings. Were the people occupying the control seats wearing their seat belts?? so lets now look into claims for whiplash, trauma, PTSD and whatever else is currently legal crap.
