Engine falls off 747
 

CHICAGO (AP) A cargo plane bound for New York's Kennedy International Airport landed safely at Detroit Metropolitan Airport after losing an engine somewhere over Michigan.



The Kalitta Air jet took off from O'Hare International Airport in Chicago late Wednesday. It later reported mechanical problems with one of its engines, a Federal Aviation Administration spokeswoman in Chicago said. The Boeing 747-R was able to fly but was diverted as a safety precaution to Detroit, where it landed without incident, FAA officials said. No one was injured. After the landing, airline personnel discovered the engine was completely gone, FAA officials said.



Michigan authorities searched Thursday for the engine, which may have fallen into Lake Michigan, the FAA said. The FAA will investigate the incident, but the results of an investigation could take weeks, the FAA said.

:ok: to that crew...I hope we find out more about it all...kudos again to that crew.

readywhenreaching 2nd August 2006 11:06

this incident is almost 2 years old

happened on 20th october 2004
ship N709CK involved, went into service again about 3 weeks later

H.Finn 2nd August 2006 11:08

This is like "a deja vu all over again", didn't this happen 20 Oct 2004, almost two years ago??

Brian_Dunnigan 2nd August 2006 11:12

Checked out the site where that link was housed...:hmm:

Dream Land 2nd August 2006 11:16

:} Sorry webmaster

One of my mates sent it to me in an email and I thought it was new.

Will Hung 2nd August 2006 11:34

Did they ever find the engine ?

Taildragger67 2nd August 2006 12:05

Same aircraft, 1997: :eek: (although from the blurb on Airliners it appears it was intended that time):

Nowadays the hardware that travels Kalitta and subsequently falls out of the sky is of a different calibre...

WOW interesting tech log entry!

Just another B defect !!:}

Bet that was a nice little earner! Long time since I had a pylon off a 747.
We don't even get a keel beam repair these day.....someone taught the buggers how to land properly!

This story is from October TWO YEARS AGO!

Why is it being reportes as though it has just happened?

pheeel 3rd August 2006 09:48

so that's where in engine came from in donnie darko :}

I thought that Boeing fixed the pylon issue after the Amsterdam disaster.

On this particluar Kalitta incident the pylon is still there, it is the engine itself that has detached.

WHBM 3rd August 2006 13:35

There have been a number of engines falling off the 747 over the years. If the inboard, it has tended to take the outboard with it. Some have led to the loss of the aircraft, others (as here) manage to get away with it.

Notable is that if I am not mistaken it always seems to have happened to freighter aircraft. Yet they make up probably only 5% of the 747 fleet movements. Their max gross weight is obviously the same and many pax 747s go out up to gross anyway. I winder why this problem afflicts freighters.

Willit Run 3rd August 2006 14:13

WHBM,
This particular incident was no fault of the airlines or the maintenence practices thereof. It was a bad part from the vendor that failed. It was the rear engine yoke that bolted to the flange of the engine case that failed.

As far as freighters go, they typically are operated at max gross weights whereever they go, unlike pax birds. That takes a toll after many years. Also, freighters often go into rather rough airstrips in remote places around the world on regular basis, that too takes a toll. Do the math, it adds up.

WHBM 3rd August 2006 14:31

I don't think freighters particularly do gross out more than pax aircraft. Yes they may well do so in one direction, but because freight is by definition a one-way load rather than the two-way flow you get (eventually) with pax, they are left finding backloads which often come in well under gross.

Then you get lightweight loads that cube out (once read of about 15 tons of shaped polystyrene foam that filled a DC-10), and freighters also do a lot more completely empty positioning to get to where the load is coming from. And their utilisation in hours per year is invariably way below their passenger cousins.

Meanwhile look at all the pax 747s operating through Heathrow, especially to/from Asia, they often seem to be up to gross in both directions.

Maybe because the old freight-dogs don't knock down the mach number a bit in turbulence and just keep on going. No worries about pax on board with dinner in their laps!

Willit Run 3rd August 2006 21:06

WHBM,
I assure you, freighters do more often, takeoff and land at max gross weight than pax carriers, I have done both. Trust me!

Flight mech, why don't you look at the turbulance penetrating speed for 747's before you shoot your mouth off. I think you'll find it very close to normal operating speed. And; Do you really think we want to shoot ourselves in the foot, rag our planes for no reason, and then have to deal with the ensueing emergemcies?? Me thinks not, ole chap. I personally want the company to stay around for another 15 years.

Willit Run,
Chill out man. I wasn't exactly "shooting my mouth off". It was only mean't as a bit of light hearted banter and wasn't even directed at your company, just frieght dogs in general. I am fully aware that the freighter guys are just as professional and competent as the ones that carry the SLF. No offence intended but obviously caused.

I'm sure some of u might remember the tragic incident in the netherlands when the no. 3 engine of a 747 freighter fell off ( rather flew off) at maximum thrust, came back, knocked the no. 4 engine off which completely cripled the right wing, reducing lift capailities. This eventually sent the big bird crashing into an occupied appartment block killing the crew and people on the ground. These accidents are the same, just with different outcomes. I suppose it depends on the curcumstances really.

No they have the important difference in the earlier event the engine that was released first was running fine at climb thrust, and as you say did fly off while in the Kalita event the turbine was trashed before it came off at pretty much zero thrust and just fell away..

HER MAJESTY WHAT A B**CH :ok: THAT GIRL HAS HEART!!! THAT IS A GANGTA AIRCRAFT:D :D :D

These incidents are not restricted to 747's. a number of years ago a cargo 707 landed succesfully on a military base in France after shedding two engines on right side, only to burn to a crisp after landing. The captain at the time was upset about losing his cargo......:*

Don't forget that a lot of the freighters have enjoyed a previous life in a self loading cargo environment.
Boeing may have come up with a fix, but the company will still have to implement it!
