Jet Blue flight about to make "soft landing" at LAX

[Cobra412]

Slinger not totally sure about the F-16 but there is no such thing as a mechanical nose wheel steering lockout on the F-15. The pin is purely to keep the gear from collapsing when hydraulics are off.

There is a mechanical lockout mechanism in the nws actuator though. It is only there to keep the tire from spinning 360. Our system also has an electrical lockout for nosewheel steering. This will completely disable nws. You also have the option for tighter turn radius by depressing another button.

I've seen our pilots oversteer enough to snap the mechanical lockout on the nws.

The pin you're talking about is the one I'm referring to.  (basically the one's you check on "AC safe for mait.")

I can't think of why you'd want to pin the nose wheel steering.

Guns, some airliners have a nosewheel steering bypass pin. The Boeings in my experience all had them. Don't know about the 'Bus.

The pin actually holds a handle in position. The handle actuates a valve which causes the steering control fluid to bypass the steering actuators thus allowing the nose strut to be rotated freely. It's used primarily during towing and when pushing back from the gate.

If it took off with said pin installed would that cause the gear to lock 90 degrees?  In addition wouldn't the pilot notice he didn't have nose wheel steering control while taxing?

That's the mystery.

It wouldn't retract if it wasn't centered and it might deflect fully at speed.

But it sure seems he would have noticed the lack of nosewheel steering as soon as he started to taxi.

I'm not familiar with Airbus systems but you'd know it as soon as you tried to turn on a Boeing.

They may have a completely different system though.

They both are from the same world, with same physics

Someone needs to find the accident reports on previous cases, where the nosewheel breaks like this.
Like the B747, which photo I posted above.
Someone also mentioned C17 doing it..  but I guess those investigations aren't released to the public.

I don't know much about this, and this may be a stupid question, but why do they put flamable paint on a runway?

It doesn't necessarily have to be flammable..
Could be that the nose gear was pulverizing the paint and the small particles of paint dusted off by the gear ignited.
Just like small particles of steel burns nicely.

And interesting coincidence is JetBlue is one of the few airlines with live TV via Sat dish to evary seat.  The passengers were watching themselves land on the TV.

Would you want to know ??

Would the TV commentators have changed their commentary if they knew the pax were watching ??

A new twist to the media game.

Mentioned on the news this AM that there have been 7 A320's with the same issue over the past 10 years.

Not really, because at least on MSNBC they were aware of it.

[midnight Target]

All the local stations in Southern Ca. mentioned the sat TV.

The fire from the video looks to me like it's most likely from a magnesium alloy wheel after the tire blew.  A pilot in the F-4 squadron I was with lost hydraulic power and was forced to use pneumatics to land. He missed the hook for the emergency arrest, and was applying pneumatics to brake the plane. But the right main wheel locked up, blew the tire and started trailing a magnesium flame. Tower told the pilot he was on fire. The plane was drifting off the runway. The pilot elected to eject, but the RIO had already unstrapped. Pilot was okay, RIO killed, plane stayed on the edge of the runway, the magnesium wheel ground down four or five inches.

Best regards,

It's a different system though. They have a cockpit switch that depressurizes ns steering. I don't know if they have a gear pin that will do that or not.

extra style points?
