Sparks and smoke blew out of the engine and stopped departing, it took off successfully after 1 hour and 30 minutes.
Delta Air Lines Boeing 747-451 N673US
It pushed back, only to have engine problems and was towed back to the spot 18.

  1. THE PLANE LOOKED DOOMED FROM THE GATE….. FIRST THING THAT WAS OBVIOUS WAS THE WHITE DUCKTAPE ON THE PILOTS WINDSHEILD, PROBABLY SOME DELTA MECHANIC GENUIS………………

  2. BA is hanging on the their 747s longer as Jet fuel prices a re low . ALL airlines should have kept more 757s! They are regretting that now. BOEING missed the mark and should have offered an upgrade 757 program Slept..service life extension program.

  3. Delta has some of the oldest aircraft in the United States. Instead of investing in new aircraft like others, they decided against it.

  4. ive seen lots of engine cowels opened up with people getting on u jyst cant tow every aircraft down to the hanger just cause u need to do something time is money and safety is everything

  5. wow jack that is hairy hearing it from you.  good thing you reported it.  it looks nasty enough looking at the video.  I would be yelling at the gate staff to have a mechanic try to get it back.

  6. I was the Captain on the inbound flight.The stator actuator on the number three engine had failed on short final, just prior to landing. We reduced thrust on that engine and made a normal landing.  The mechanics thought they had repaired the actuator, but that proved not to be the case. When the outbound crew attempted to start the engine, it resulted in a hot start. They aborted the start and returned to the gate.  The engine was repaired and the flight departed for Manila.

  7. Lots of misinformation here.
    First off, the PW4056 engine has full FADEC (Full authority digital engine control) and therefore does not have a manual fuel input.  Secondly, as the 747 APU often starts two engines at once, the difference in rotational speed of both three and four shows that the problem is friction within the engine preventing it from spooling up. Then the sparks at circa 1:20 show that it is indeed a frictional fault, and most likely from the HPC (high pressure compressor), as these engines have a history of problems with the synchronizing ring and the leveling arm pins on the VSV (variable stator vanes).
    At around 2:00 you can see they try to start it again, and the much slower N1 speed accompanied with smoke means the initial start attempt has allowed a lot of material from the HPC to go downstream to other HPC discs, the annular combustor nozzles, the HPT and the LPT.  In other words, blade tips rubbed against either the cause or the stators and the resultant friction blasted fragments through the gas path and destroyed the engine. 

  8. For looks the -400 has perfect lines. The -800 looks spindly and emaciated. The same goes for the new 737MAX's. Cost per seat mile the -800 kills the -400 with all of that 787 technology going into the -800.
