Flames From MD80 Engine At PHX Yesterday

Sat Jun 12, 2004 12:10 am

HI,

I was flying from PHX to ORD yesterday on UA. While sitting on the taxiway for takeoff clearance I was watching a stream of departures from Rwy 27R. I was observing an AA MD80 taxiing toward the runway when all of a sudden a gush of flame spurted out from one of its engines. It was only for a brief moment but it startled the heck out of me. I was very tempted to press the FA call button and have this reported to the tower... but decided against it since I have seen such pictures on A.net before. I closely watched that flight take off, and believe me, I was praying until it vanished from sight.

My question is, how common is this phenomenon? What causes it, and is it dangerous? Should I have called a FA and asked her to have our pilot inform the tower or the other a/c? For the record, it was around 4:30 PM yesterday and the temp in PHX was probably around 95 degrees F.

What happening with MD80 was got problems with engines. I will sure will they repair with the engines problems on AA.

I do not believe it was a problem. We have 1 727 with a different fuel cut off/ fuel on. IF They move the start lever past the detent to the run position they will get a blast of flame from the engine. Since we only have one A/C like this the pilots sometimes forget and poof....We get flames. This is not a big deal providing it doesn't happen all the time. Perhaps American has an A/C like this.

I am not saying this is what happened just tossing out a possibility.

Sometimes a bit of fuel accumalates in the combustion chamber, when the engine is started it ignites and creates a bit of a flame that is discharged out the back of the engine. This also happens from time to time with APU's.

Its a new modification from Boeing: Afterburners for the MD80s to allow for those quick climbing departures out of noise sensitive areas.
Pilots are idots, who at any given moment will attempt to kill themselves or others.

An article I read yesterday was about the different ways airlines are conserving fuel these days. One of the methods is to taxi with only one engine while keeping the other engine off until close to the departure end of the runway. Its possible he was starting up that 2nd engine while deep into his taxi.

I am thinking what you saw was a rollling crossbleed start of the second engine. Many jets will strat one engine begin a roll to the runway and will be starting additional engines in this manner. Sometimes you will see spectacular displays of flames and smoke when this occurs on a cold start.

At AA we call it "engine torching" or "APU torching", depending of course on where it originates  Smile/happy/getting dizzy

Thanks everyone for your replies... I would have indeed looked like a fool if I had tried to alert one of our FA's about this.

Well any aircraft departing from 27R in PHX is doomed since there is no such runway!

Actually very common....a said above, at idle some fuel builds in the combustion can, then when power is applied it flashes off giving you a quick 'afterburner' effect. If the aircraft was not yet out on the runway, he may have just started the engine that engine... when the same thing happens. During the take off roll, the crew monitors several things including Fuel Flow and ITT.. any shift in these would indicate a problem.

22right -
About you looking like a fool. Pax comments have been known to prevent accidents. And there are many accidents that may have been prevented if pax had of spoken up. (British Midland 737-400 in Kegworth 1989 for one and and Air Ontario F28 in Dryden with snow on the wings. Another was the lady who saw a hole on the fuselage on the Aloha 737 as she was boarding - we all know what happened then.)

My point is you shoud feel confident to bring any concerns to a crew member. FAs should communicate it to the flight deck if they too cannot explain your concern.

That happens when the MD80 has beans for lunch. Nothing to worry about.  Yeah sure
