Gulfstream landing w/o nosegear in LSZH
 

according a swiss newspaper website, a Gulfstream jet landed yesterday evening in Zurich with a retracted nose-gear... all occupants unhurt..

Does anybody have details?

Hey...

I dont have details of the incident. But i was listening to ATC at the time.. the pilot just requested an emergency landing, then informed ATC that he wanted an extra time to dump fuel and prepare the pax. He kept his cool and things were sorted out within half and hour..

I seriuosly doubt that a Gufstream can dump fuel ...

According to Swiss TV coverage it seems to be HB-IMJ, a 1997 G5, inbound to ZRH from Rotterdam. 4 Crew and 5 pax.

Probably wanted extra time to burn off fuel.

Why do you say that?

Maybe because it can't...

I have no idea whether it can or not. I was more interested in the "....seriously doubt..." part.

Don't worry, it can't.

Worried? Me?

All that money and no fuel dump facility? Pffftt!

Gulfstream dump facility
 

there are often two dump facilities, but a major problem getting the fuel into them.....the plumbing is non standard.

Hmmm, now I'm curious. One says it can't, another says (theoretically) it can.

Joking aside I'd be surprised if it can't considering that a more 'lowly' aircraft like the CL604 can (to a point).

Flintstone, FAR 25-1001 (?) Fuel Jettison System, states that an aircraft must be able to satisfy the approach climb, landing climb criteria within 15 minutes of takeoff. With or without a fuel jettison system.

If an aircraft can satisfy the requirements without the fuel jettison system, it wont be installed, e.g. B737.

In some cases the fuel jettison system becomes an airline selectable option, e.g A330.

So it reasonable to get two different answers that will actually be correct as they will apply to the same model of aircraft but different certification requirements or purchased options.

dumping fuel
 

Period. none of the Gulfstream 4 and 5 series incl 450 550 can dump fuel. that is the straight answer to this questions.

but than.. there is no such thing as a overweight landing in a g5 or 550 its a heavy weight landing and the onboard accelometers will determine if you need a inspection or not in case you once have to land over max landing weight.

and it is probably a good idea to burn of that extra fuel if your nose wheel is not down........ anyway.. good job you've done there dude in ZRH. i am proud of you... the beer is on me ..

A very good job done by the crew, glad everyone was safe.

A good job done by the captain proud of you.

Swiss BFU initial report
 

No such thing as an overweight landing in a G500/G550? I don't think so. How about, if you don't trigger any exceedences with your overweight landing, you do not have to do an inspection.

From Gulfstream; "There are procedures in Quick Reference Handbook that permit a landing beyond the normal landing weight with no follow-on Overweight Landing Inspection required. The QRH Overweight Landing procedures notes that "The overweight landing inspection is not required if the recorded landing vertical acceleration is within limits." If the maximum vertical acceleration recorded during a G500/G550 landing is within the parameters of this chart and no extremely high side loads were experienced, it is considered a normal landing and no inspection is required, regardless of the aircraft's weight."

Overweight landing inspection Gulfstream V from the engineering dept!
 

Gulfstream V Maintenance mannual Chap.5-50-00 page 618.
I quote:-

Para. b

'An immediate check of grease marks on the shock struts should be made. If main gear shock struts closed to within 1/2 inch of maximum available travel and nose gear closed to within 1 inch of the available travel, then this is evidence that limit vertical loads have been exceeded'

Para c
'was it a two or three point landing? (Most landings are two point and there is no need to worry about nose gear unless there is evidence that it was actually involved)

The aircraft in question definitely did a two point landing and the nose gear clearly did its best to stay uninvolved!!!!!

Fokkerjet,
Hows it going old buddy? Its been long time, still in the motor business?
We must catch up again soon, best regards.

:)

Hi Stress.

The checks are still clearing at the bank! :}

Been some changes over the last 6 months; of course none of which were good. What's up with the BAE 146 in colors?
