Flights in & out of MEL suspended due to Vietnam Airlines incident on the runway

Nine News is reporting that all flights in and out of Melbourne have been suspended due to debris on the main runway from an incident during the aborted takeoff of a Vietnam Airlines flight.

Some flights seem to have diverted. A Qantas 767 just landed in Canberra.

Edit: I see that this has also been posted in Travel News.

Plane catches fire on Melbourne Airport runway

Quality journalism - headline says "plane catches fire", body of article says that the aircraft had not "caught fire at any stage". :-|
Blazing debris falling out of a plane during take-off at Melbourne Airport caused havoc after all flights were suspended late on Tuesday morning.

I have to say having just flown around Vietnam on VN for the last couple of weeks that a blown tyre doesn't surprise me. The quality of runways and taxiways in Vietnam is shocking and the tyres take an absolute hammering on takeoff and landing.

News now reporting that flights have resumed.

Sounds like it was a compressor stall rather than anything to do with the gear.

ABC News says:

"A passenger on the plane told ABC local radio that the nose of the plane was just leaving the ground when something went wrong.
The passenger, Peter, says the plane pulled up suddenly and came to a halt on the runway where it sat for about 30 minutes before finally moving towards the terminal.
He says passengers were told that engine two failed."

Is someone able to tell me whether this is possible? That is, can a plane abort take-off after the nose has left the ground? Isn't V1 before the fronts wheels come off?

Anything is possible, aborting after Vr normally only occurs if the pilot feels it's not safe to continue.

Also might depend how long the takeoff roll to V1 was and how long the runway is I'm guessing. (As to whether they can come to a halt)

Take offs aren't aborted after V1 which is the calculated based on the stop distance required. V1 is always either equal to or less than VR (the rotate speed). In other words, once you've rotated, you take the problem into the air.

Thats the theory, in practice not always the case though, I was on a Northwest 744 No 1 to land when TWA843 aborted. In practice it's hard for pilots to stick to the mantra although the outcome is predictable re overrunning the runway:

1. Britt Airways Fairchild SA-266TC, Galesburg, IL, 9/24/1986 -- a/c aborted takeoff 5knots above V1. Aircraft stopped on runway.


2. AA. DC-10-30, DFW, Texas, 5/21/1988 --aborted at V1 due to faulty slats disagree light --overran runway due to worn brakes.


3. Britt Airways, Fairchild SA-266TC, Cleveland, OH, 8/16/88--aborted at V1, overran runway.


4. USAir Fokker F28, Charlotte, NC, 4/15/92 --aborted 5 knots after V1, overran runway.


5. Continental Airlines MD-82, Flushing, NY, 3/02/94 --aborted takeoff due to iced over pitot, overran runway -actual speed was 5 knots above V1.


6. SW Airlines 737-200, Nashville, TN, 7/08/96 - bird strike after V1 near Vr, takeoff aborted, overran runway.


7. Air France 747-228F, Paris, France, 9/11/98 -- 3 seconds after V1, aborted takeoff due to cargo bay fire warning, overran runway.

There are a lot of others if you look closely, GA at FUK aborted after V2 http://aviation-safety.net/database/record.php?id=19960613-0

Boeing have an interesting paper on RTOs:

So realistically then factors such as the condition of the aircraft brakes, tyres and so on, the condition of the runway and the sharpness of the pilots will all play a role in a successful stop at V1. (Or otherwise) 150mph is 67 meters per second.

The aircraft is certified to stop if takeoff is aborted at or below V1. Above V1... Anyone's guess.

There have been instances of aborts above V1 before and the outcomes have been described above.

It wouldn't be a pleasant meeting where one has to explain to the powers that be why a standard procedure wasn't followed.

If it isn't parked in the grass, then that isn't what happened.

V1 and Vr can be at the same speed, but, on a fairly heavy flight going to Vietnam, I'd expect them to be about 30 knots apart.

was accelerating for takeoff from Melbourne's runway 16 when the right hand engine (PW4168) failed causing the crew to reject takeoff at low speed (just above 30 knots)


That's a quote from the ATSB...so I guess the passenger report wasn't all that big on accuracy.
