What would cause that?
Gust lock engaged while powering on.Speed relatively constant and massive altitude variation?
What would cause that?
Automation failure?
Indication Failure?
Prior to 2016 is was managed by Solarius roughly since new.Well, the thing was registered in the DR, maybe the tape holding the wings on caught fire.
I'll just get me coat...
The gust lock on a G-IV will "lock" the elevators in a decidedly pitch down position making it very difficult to take off, and that's only if the "lock" is failed on the power levers as well. Not to mention the ailerons and rudder. Gust locks have killed Gulfstreams but this doesn't fit that mold, something else happened IMHO.Gust lock engaged while powering on.
When you disengage, residual pressure keeps them locked.
Proper procedure is to disengage prior to start the engines...
That was the rumor I heard
Happened before.
Check lists have a raison d'être.

NTSB Faults Pilot Compliance, Gust Lock in GIV Crash | AIN
NTSB is issuing a safety alert on pilot compliance and calling on FAA to mandate modification of the gust lock system on Gulfstream GIVs.www.ainonline.com
I wish we still had the sarcasm emoji. It was meant as a joke. It sure seems like everyone here is wound really, really tight these days.
The gust lock also inhibits adding full power. How did they get airborne in the first place?Gust lock engaged while powering on.

And what's wrong with a mammary obsession?WTF is this garbage?
I saw video taken by a mobile phone pointed at a security camera monitor replaying video that appeared to correlate with the ADS-B plan view. It looked like the aircraft crossed near the runway threshold/clearway, but was not aligned and crashed into an area with trees. They were close.
Maybe because it was improperly disengaged ?The gust lock also inhibits adding full power. How did they get airborne in the first place?

As a result of the Bedford accident there's an inspection that has to be performed with regards to the gust lock. A protractor (special tool from Gulfstream) will be installed between the power levers to measure how much travel exists with the gust lock set is part of it. I've done that functional test plenty of times after the AD that required a rework of the gust lock system and none have failed. I wonder if the AD was complied with and whether or not whoever was taking care of the airplane has the protractor?Maybe because it was disengaged ?
Excerpt from the NTSB;
" During the post-accident investigation, Gulfstream discovered that the gust lock system, “while limiting movement when engaged, did not achieve its stated six-degree throttle movement limitation.” A subsequent investigation of gust lock systems on nine GIVs revealed that none met the design intent and each demonstrated 18- to 23-degree throttle movement (three to four times the design intent). "
So a certain power could be applied but enough pressure on the lock remained, thus impeding the proper movement of surfaces. Post MA crash, there was a lot written about this. I didn't get a chance to read about it. As soon as i can I will do so.

I was a lot more than 15 I just can't even remotely understand it.If I recall correctly, there was evidence that they didn't use any checklists for the previous 15 flights, too.
Sent a DM, prefer to not post footage of people dying.
Pearl-clutchers gotta clutch……People die all the time. Let's not clutch our pearls, here. Someday, we're going to die.
