UA497 Smoke, Emergency Landing and Evacuation

KENNER, La. United Airlines flight 497 had to make an emergency landing at Armstrong International Airport this morning. Airport officials reported smoke in cockpit and immediately landed the plane around 7:20 this morning.

Once landed, passengers had to use emergency chutes for a safe exit from the plane. Some passengers are complaining about smoke inhalation. The flight was headed to San Francisco for a 7:07 am departure.

English has improved.

KENNER, La. (AP) A United Air Lines flight from New Orleans to San Francisco returned to the New Orleans airport within minutes of taking off Monday after rocking back and forth.

All 100 passengers and five crew members on Flight 497 were safe, airline spokesman Rahsaan Johnson said.

Copilot Ronald Lee Young told an Associated Press reporter aboard the Airbus 319 that he landed on backup systems, with minimal steering and braking ability, after the plane lost all electronics.

"When things start to go wrong, there's always a system ... we can go back to," he said.

He said the plane, heavy with fuel, ran off the runway and blew a tire.
Journo on board, so first hand.

US ATC

Having an emergency in the US is such a pleasure with ATC on your side. I departed a major airport in a very large Asian country recently (in the same type - A320) and asked for vectors back to the field due to a problem I won't go into here - and was told to maintain the SID which took me further away from the airport. Had to declare a PAN to get what I wanted.

Approx 9 miles out
Ground crew "we need three minutes to clear (construction vehicles from) the runway"

Approx 7 miles
UA497 "lost all our instruments right now and we are gonna need just a PAR"

Approx 5 miles
UA497 "we've got the water we gonna stop here at about 600 feet"


Not an ordinary day at the office.

The freakin' bonger !

I've had a listen to the ATC recording (from skidbuggy's link), as well as a few others over time - Sully's Hudson River landing, the Thompson 767 bird ingestion video on Youtube, etc. I know you'd expect it, but nevertheless it's very comforting to see how hard the controllers try to help a plane in trouble.

Now, an SLF question that may be a bit off-topic.. In the background of the UA497 transmissions I could hear the alarm bonger sounding continually. I can imagine the tremendous pressure that a cockpit crew would be under in an emergency, and having that damn thing beeping away would drive up my stress level to breaking point. Is there any way to permanently silence that ? I'd take to it with the fire axe as the first thing on *my* checklist.

TRANSCRIPT OF AIR TRAFFIC CONTROLLER, PILOT CONVERSATION

UA 497: Clear for takeoff runway 19, thank for you very much.
UA 497: We need to vector back to the airport, we got a smoke issue with the airplane.

New Orleans Tower: I'd say they are about 11 miles to the west.
Airport operations: Tower, we can start trying to pull them off, but I don't think we will get them all off in time.
N.O. Approach: United 497, Say souls on board and fuel remaining.
UA 497: 106 souls on board, fuel remaining 32,400 pounds.
N.O. Approach: They are still trying to get all the vehicles off the runway and 19 is still available if you like....
New Orleans Tower: ... working as fast as they can (unintelligible) There is a bunch of equipment on there they're tying to get off now.
UA 497: You need to clear it for us.
New Orleans Tower: I understand, sir. We're getting them off as fast as we can.
N.O. Approach: Turn right heading 140, main 2,000 ....cleared ILS runway 10 approach.
New Orleans Tower: Can you verify the vehicles are exiting?
Airport operations: We are attempting to get the vehicles off right now, I'm removing the cones also.

Reading this I thought of all the times that I was on inactive runways and also what I thought were inactive railroad lines. I was generally nervous only because I was dependant on somebody else to warn me what to do in an emergency.

I did have one emergency pop up where we were told to clear an inactive runway for an emergency air-turn-back. That was simply handled because my driver was part of the airport management and always had the tower on the frequency.

Makes one wonder if all non-aircraft runway operations should include a bulldozer among the equipment - to ensure the runway can be cleared on three minutes notice.

Shades of Airport. "In case of emergency, break trucks!"

I have sim'd for fire warning more times than I care to remember and it has to be my worst nightmare.

BIG pat on the back for the crew

Curious thing but thought I'd pass it along. It applies to Airbus but I can't say if it's the same for Boeings. In the aircraft (not the sim) the lenses on the O2 masks have a protective plastic film over them to protect against scratches when they're stowed in the box. It's easy to not notice them in the heat of the moment (sorry about the pun) but if you don't remove the film when putting your mask on, they can do a nice job of obscuing your vision in an already difficult situation.

I believe this 'film' is there to degrade vision for sim purposes.

that he landed on backup systems
If he lost all instrumentation:

UA 497: (alarms blaring) We've lost all our instruments right now and we're going to need (directions)
does this mean he was using mech backup or was he still using the FBW system for aircraft control?

there is no mechanical back up for the Flight Control System. They are talking about flight instument failure I believe - not flight control system

PAR capability?

I thought Precision Approach Radar disappeared from [most?] airports decades ago. Mis-remember?

KMSY, unlike most airports, still has ASR approaches:

@flyingflea: The A32x does indeed have mechanical backup in the event of total loss of the FBW system. It comprises the stab trim wheel for pitch and the rudder pedals for roll control.

The FBW system itself has Normal, Alternate 1, Alternate 2 and Direct Laws.

Given the smoke, assumed electrical fire, and loss of avionics, I wondered if the FBW had been adversely affected as well (thinking back to electrical generator problems on another flight where FBW was also affected by the fault leading seemingly to temporary loss of control).

It was more curiosity than anything else.

* Patiently awaits initial report *
