This wasn't a "normal" separation where the securing bolts shear. This looks like the entire pylon came out!

How are these aircraft maintained/inspected?

Why still these old planes?

So now that this has happened I hope people are going realize that this old 737 should be taken out of service, I mean really now, look at all the other airlines, they using newer models now. Besides when I lived in Jhb whenever a really noisy plane took off and I looked outside it mostly always was the 737.

Or a 727, or a DC9, or an IL-76, etc. When in Africa............

If the engine had to fail,and if of course there is no dramatic wing or tail structural damage,if the balance can be maintained,it's better to leave a couple of unecessary tons of dead metal on the ground,you'll be lighter for the initial climb.
Then is it usefull to spend precious time burning extra fuel,considering the dire emergency and the unfortunate "loss of weight"??

The 732 doesn't have a pylon as such does it? just the engine slung on the wing.

I don't know the 737 systems, but I would imagine such a separation would probably also cause significant hydraulic, fuel and electrical system damage, much more so than a failed engine.
I wouldn't be surprised if that little lot didn't take a long time to work through all the checklists.
As long as the aircraft is flying, there is no fire, fuel isn't peeing out at a huge rate, and everything is stabalised - i.e no further hydraulic or electrical degradation after the initial damage, then where is the urgency to get back on the ground?
Better to make sure you've run through everything, maybe also 'fly' it around a bit in a few configs and speeds to check everything else on that wing is still where it should be.
ISTR that where a separation has lead to a total loss (DC10, 747 Amsterdam) it was mainly due to some high lift devices being damaged, or retracting due to the hydraulic loss and when the speed came back the aircraft bascally dropped below the new VMCA. Why rush back and risk that scenario just because you were too hurried to work all the QRH items?

Apparently, they lost hydraulics with the separation and were also losing fuel the whole time. The gear stayed down due to the loss of hydraulics.
There is also an account from someone listening in to the radio transmissions between the tower and the a/c.

Engine out

Sounds like a good engine out drill, continued the climb out, circled and burned fuel off, acsa (airport chaps) cleared the crumbs and put her down in one piece. Star performance ek se....

Ern DSM:

The problem is if they were to ground all the 737-200 Adv out there, it would leave the low cost companies with a desperate shortage of machines to operate!
They are mostly old SAA airframes I believe, cheep to purchase but I would imagine rather expensive to operate, and the older they get, the more expensive they will get, I feel that sooner or later these low cost airlines will have to have a rethink, although I think Nationwide is in the process of upgrading to the 300?
There are also a few others using the 200, BA/Comair, Kalula etc.

Now that you mention it I do remember seeing Kulula and BA comair using 1 or 2 of them aswell. I still think they all can do without them! Thats why SAA got rid of them, because they are old junk. Well I just hope something like this doesn't happen again because you never know what else could go wrong once an engine falls off during take-off or in mid flight.

quote "She said that while the plane was making a wide turn and dumping fuel, the cabin crew took the passengers through the emergency procedures, getting them to take off their shoes and practice bending down."

Why the shoes off unless they were expecting to waterland?

And does the 732 really have fuel dump devices?

shoes off in case they need to use the slides. Try jumping out of the door of an aircraft after someone has punctured the slide with their high heels.

And does the 732 really have fuel dump devices?
nope. However this one did after the pylon fell off leaving the pipe open!

Nothing to do with a "waterland". It's essentially required to ensure that the heel of a shoe (especially a lady's high heel variety) doesn't tear up the slide should it need to be used.
However, I'm not entirely convinced that it's a good idea to escape from a wrecked (if applicable) aeroplane shoeless!

Edit: 757 driver's fingers were quicker than mine.

SAA got rid of their B737-200's not because they were "old junk", but because the taxpayer payed for new -800's.

And they still have some operating as freighters.

The problem is maintainance. the older the machine the higher the cost to maintain it. SAA technical maintains all the BA & Kulula Boeings, but Vernon can do it cheaper himself, and it shows...............

Ruan, it wasn't a disaster.

Could have been........but stayed an incident.

Avman asked "Why the shoes off unless they were expecting to waterland?"

So they wouldn't puncture the inflatable escape chutes I would imagine!

Better to keep your shoes on in the water because it slows down the loss of body heat but then you really should have them off before getting in the liferaft.

Igh,
An engine detached from an Aer Lingus 737-200 about 20 years ago when it struck birds on take-off from Dublin. If I recall correct the forward fuse-pin/s or cone/s (can't recall which) failed leaving the engine slopping about held by just the cable and the rear pin or cone which didn't help as the aircraft was hard to control. Still, they landed safely.

757 FLYER...[As long as the aircraft is flying, there is no fire, fuel isn't peeing out at a huge rate, and everything is stabalised - i.e no further hydraulic or electrical degradation after the initial damage, then where is the urgency to get back on the ground?

and why not trying some touch and go?
How long this old lady will fly,can you be sure?
To land,to be sure "everything" has been done,you need: a runway,long enough,but you took off from there...gear and flaps,if possible...emergency assistance from airport...as much as possible a cabin ready for emergency ,but if you loose a wing...
This is my humble opinion,in these circumstances ,K.I.S.S. (Keep It Simple Stupid)

The pics posted elsewhere on this website (too bad we can't have just one thread) appear to show the inlet cowl separated and mostly round. This doesn't correlate with the other mount cone-bolt failure pictures.

I really don't understand the hydraulic failure condition being talked about. The loss of one engine should be reasonably accomodated in both fuel loss and hydraulic loss. Is there something else going on here?

Can somebody post a link to some better pictures?

Nationwide Airlines
Press Statement
08 November 2007 – 14h30
Nationwide Airlines Salutes Pilots and Crew
Nationwide Airlines Chief Executive Officer Vernon Bricknell today complimented his entire staff and in particular the Captain and crew of Flight CE 723 for their heroic efforts in helping to maintain the company’s outstanding safety record.
Flight CE 723 was discontinued following an incident yesterday soon after take off from Cape Town International Airport.
Bricknell says this is the first major incident that the airline has experienced since taking to the skies 12 years ago.
Bricknell says he is relieved that the incident, which took place yesterday at Cape Town International Airport, did not result in injury to passengers or people on the ground.
“Upon take off of Boeing 737 Flight CE 723 yesterday at Cape Town International, the captain heard a loud noise immediately followed by a yaw of the aircraft. The captain, after confirmation of information from flight deck instrumentation that one of the engines had failed, immediately applied emergency procedures, an emergency was declared and the aircraft returned to make an emergency landing in Cape Town,” says Bricknell.
Nationwide Airlines has since determined that during the take off roll an object which is yet to be defined was ingested into the engine causing engine failure. The subsequent forces experienced by the engine supporting structure caused this to fail and for the number two engine to detach from the wing. The engine-to-wing supporting structure is designed to release the engine when extreme forces are applied to prevent any structural damage to the wing that may impair the aircraft’s ability to fly.
He reiterated the fact that the Boeing 737 aircraft is by far one of the safest aircraft in service today. “The Boeing 737 is aviation’s most successful story,” says Bricknell
According to Bricknell, there are approximately 5 000 Boeing 737 in service around the world, with one Boeing 737 taking off every 9 seconds, every day.
He says Nationwide Airlines is working with the proper authorities to establish the nature of the unidentified object and will keep the public informed as more information becomes available.
Furthermore Bricknell says Nationwide Airlines has met and surpassed local and international safety best practice standards. The airline is accredited by IOSA, the Operational Safety Audit of the International Airline Transport Association (IATA).
He says the airline industry is the most regulated sector in the world in terms of safety, training and aircraft maintenance.
‘In no other profession are skilled individuals such as pilots required to undergo testing and to demonstrate their proficiency on such a regular basis. Training encompasses a wide variety of subjects and scenarios that hopefully flight crew members will never be called upon to exercise in the operational environment. Yesterday this training paid off – the skills of the crew were called upon and procedures were carried out in a text-book fashion,” says Bricknell.
Nationwide Airlines is a privately owned airline company which flies to local, regional and international destinations.
Ends.
ACSA refused to let photographers get anywhere near the aircraft, so the pics available are not that great.
