5 hours definitely sounds like the gear wasn’t locked and could collapse so they had to plan on how to either lock it or get it off the runway without collapse
@@bluecrayon007 You might be on to something there. I would have thought the 763 has pins that can be places to lock it manually though. Maybe someone knows the answer to this.
@@Republic3D Down and locked mean that the gear has extended beyond the center [vertical ] position of its travel. This is called the OVER CENTER position where the weight of the aircraft plus hydraulic pressure keeps the gear in its selected position. In the absence of hydraulic pressure, the gear when unlocked from the up or retracted position will fall with enough momentum and help from the relative wind that the structures will end up slightly over centered. On landing, without hydraulic pressure the weight of the aircraft on an over centered gear will prevent retraction but only when the wheels are over centered can the physical metal locks be properly inserted. You may need jack stands under the aircraft before personnel can work under the faulty gear and wing to do any maintenance. I suspect that was the long delay.
Probably because it didn't matter. They had, presumably, already tried all the options to get it down & locked, so whether it was in fact down or not isn't really relevant.
Your visual shows the plane landing on 13R just in case you hadn’t noticed. ☺️ I’m totally intrigued now as to what kept them on the runway at JFK for 5 hours. That’s a looooong time. I’m assuming the stability of the gear couldn’t be confirmed, but even so would that really take 5 hours?
@@YouCanSeeATC Okay I think I misunderstand the visuals then because the runway the airplane shape lands on is labelled 31R. How do they work then - is it also the L?
@@clemrivers9861 Yes, on the diagram at the end of the video if you pause it, the plane silhouette is on a Runway labelled 13R. That’s what I meant. ☺️ Not that the plane itself didn’t land there, just an editing error I thought I was pointing out.
I’m no pilot, just an armchair aviation enthusiast - the I believe that gravity drop still doesn’t guaranteed the gear is safe and locked in position. In any case in this instance they had conflicting information meaning they weren’t able to manually deploy anyway, because cockpit indicator was telling them the gear wasn’t down, however the gear actually was already down.
@@staceygrahame2504 - actually, you are right to some extent so I apologise for being too quick to comment. I’m not sure about the 767 but I’ve looked up the checklist for the 777 and it tells the pilots to activate the alternate release of the gear. This releases the unlocks so will help if the gear is up but not if the gear is down but not locked. The advice then is to just land and see what happens. It is an airlines procedure to allow a fly past or not.
Weird that you have to “lower fuel” on arrival to destination, and very convenient. Over an hour endurance! Normally, such failure means increased fuel consumption and u don’t have all the time in the world
@@RastrojeroDiesel1 In a perfect world the B737 Max would not have happen either. But apparently we are living in last stage capitalism where corporations tell the regulators what to do. This incident with LAN comes from personal experience dealing with the airline and 20 years of AC MX experience. I know what Airworthy is "Suppose" to mean! It no longer does! these airplanes are not getting inspected upon arrival and until someone dies no lawyer will touch the issue! and the FAA just looks the other way apparently.
Closing 31L at JFK for 5 hours because of this is a bit strange. There must be more to the story than just an unlocked indication.
Unfortunately, this is all I know.
One guess: The landing gear was down, but it was not sure as of it was safe in this position or could suddenly collapse.

If it took hours to move it after they got down? That gear was not locked and they lucked out.
Why did they decline the low approach?
I was just about to ask the same thing
Some airlines don’t allow it.
Because they misunderstood what ATC was saying. They responded "We are not ready for approach yet". They missed the other part.
Because the tower could only determine if the gear was "down", not if it's "locked". Crew made the right call

Hello, they landed on 31L. Visual shows that.
@@YouCanSeeATC I think Stacey meant that the runway was labeled "32R" in the visual.

@@YouCanSeeATC Sorry if I wasn’t clear, I think you misunderstood what I meant because I was talking about the airport ground map you created. ☺️
A LG leg can be down but unlocked
Maybe a 767 pilot can explain this to me, but wouldn't they just do a gravity drop and it's then no big deal?
The gear is already down.

@@EdOeuna “Land and see what happens.”
That instruction is so tragic, yet it absolutely does not surprise me that it’s an actual written protocol! 😅🙈

So I was right about the landing gear..
N532LA left JFK yesterday, too.
Move the dang mic away from your mouth!!!!
i struggle to understand even half of what this pilot says.
without the subtitles i'd just quit completely.
LANTAM is a horrible airline, does not comply with Airworthiness Standards and continues to jeopardize the life of crew and pax for profit.
That's incorrect, they wouldn't be allowed to fly to the US if they did. What's the source for what you're stating?
