737-200 Loses Engine On Take-off In CPT

Wed Nov 07, 2007 3:29 pm

Apparently a Nationwide 737-200 lost an engine on take-off at CPT.
The aircraft was seen heavily smoking and diverted to a nearby airport.
Engine came loose after TR buckets deployed causing the engine to shear off.
737 is ex LH build in '81 reg number ZS-OMG

how does an engine just fall off a plane, i must have just come in from JNB or DUR before leaving again fro JNb so it had just done a flight?

Must have been a pretty scary landing. Not only one engine but I'm sure quite a few other systems would have been affected.

Ahh - that makes it perfectly clear  silly 

That guy sounds about as shocked as the passengers onboard would have been! Still, I believe on older aircraft models like the 737-100/200 that the engines were attached with sheer pins, which were designed to sheer off in case of an incident? I'm sure someone will know the full details - but I seem to remember reading this in a book once.

Quoting CraigW (Reply 3):

When AA191 (DC10) crashed after losing an engine at ORD, It was discovered the damage had occurred quite a while before the accident. Several cycles had been completed with no problems or indications of a fault, but during the fateful take off roll, the forces on the damaged mounting simply became too great and ripped the pylon and engine off (and the hydraulics and captains instrument power supply).

Wed Nov 07, 2007 4:08 pm

The JT8D engine on a 737-200 is attached to the pylon by two cone bolts in vibration damper mounts forward and one cone bolt aft. The aft mount also contains a second safety backup bolt. Just above the T-R is a decal with a green line and an arrow pointing at it, which shows if the rear mount came loose. If the rear mount is defecttive and the engine only held by the backup bolt, the arrow will not align anymore with the green line.

737-200 Loses Engine On Take-off In CPT

Wed Nov 07, 2007 4:21 pm

There have been a number of 737-200's that have had engines fall off; all of them have landed safely. A 727 lost an outboard engine once after ingesting "blue ice" from a leaking toilet; it also landed safely. I don't know if any 707's have lost engines; I would be surprised if none have. The only Boeing plane that has crashed because of an engine falling off is the 747; and it happened to two of them. One was the El Al cargo plane that crashed in Amsterdam, and that was because when first engine fell off it hit the other engine on that wing (the first one fell off because the fuse pin failed from fatigue) and knocked it off as well, but more importantly destroyed the leading edge slat between the two engines. This caused the same effect as the DC-10 at Chicago, which crashed not because the engine fell off but because the slats retracted when the hydraulic lines were severed and the pilot was unaware of it. The same befell the El Al plane. A China Airlines 747 also had a very similar accident with the same outcome; the 747 pylon attachments were redesigned as a result. Boeing's philosophy was that they would rather have an engine fall off then do structural damage if it became too unbalanced (from losing fan blades, or some such event). This works fine on a twin or even the outboard engines on the 727, but causes problems on the inboard engines of quads.

Good memory, and the only thing I'd note is that the single aft cone bolt has a cable as a back-up, not another bolt..

All the comparisons with other aircraft are apples and oranges, the cone bolt issues on the 737-100s and 737-200s are, or were, well-known. Increasing inspection intervals seemed to resolve the issue here, and I don't think the industry saw any more problems since the last-1980s. Whether adherence inspections elsewhere is as compliant is another matter.

As I said in my previous post, it goes to the design philosophy that Boeing has had on its jetliners, which has worked on most but not on the 747. I consider it reassuring that, of all of the things that can cause an airliner to fall out of the sky, an engine falling off a Boeing twin is not likely to be one of them.

Or "pilots", even.

Many years ago an Aer Lingus 737-200 (EI-ASA, I think) struck a flock of birds on takeoff at Dublin and one of the engines was badly damaged, to the extent that its aft mounting failed and it was retained by the cable that has been mentioned earlier. The aircraft managed to limp back for a landing but at one stage the crew considered that they might have to put it down short of the airport if they did not make it.

Here is a report of a 707 from which an engine detached in flight over France in 1992 but which just managed to land safely, though the aircraft never flew again. http://aviation-safety.net/database/record.php?id=19920331-0

I recall that a USAF KC-135 also suffered the loss of one, or maybe two, engines during GW1 in 1991 but managed to land safely.

The crushable stuff may have been there too but I -know- the cable was, since that's all the aft part of the engine on ours was hanging on by when it landed, back in the mid-1980s.

In fact, just about every 737 engine cone bolt problem in the USA I can recall (US at PHL, PI @ ORD, DL@DFW, and our partial at DAL was back roughly in the 10 year period of the 1980s, give or take a year on either end. Bad batch?

Just had a look in my old books. At least the LH 737-200 (I did my apprenticeship on them and also my practical exams for qualifying) didn't use a cable but a long bolt as secondary restraint. The secondary bolt was normally not carrying any load, and so that it wouldn't be overloaded by a shock load should the cone bolt fail, it was attached to the engine via a crushable honeycomb block, which would deform and slow the application of load to the secondary bolt.

737-200 Loses Engine On Take-off In CPT

Thu Nov 08, 2007 12:39 pm

At least the design of the 737 and the particular way this incidnet occured as well as well trained cockpit crew meant a good and safe emergency landing. I bet some heads may roll at the mx facility for this failure. Of course, there is a delicate balance of engineering as to engine mounts so that stay on, but can shear off in case of certain extreme circumstances.
Don't forget the Kalita Air 747-100 freighter that lost an engine into Lake Michigan in the USA a few years ago. The a/c was able to land safely a short time later.

What if one of these engines fall into an urban area? Central London, packed sports stadium, as examples.

I would have thought there were far more safety measures to ensure engines don't just fall off.  Confused

Update:

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.

I just can't understand why these old planes are still allowed to fly. Even if they are maintained well, I would rather prever seeing them in the museum than flying on them...

From the Independent Online (South Africa)

""The guy next to me seemed to know something about planes. He said, don't worry: the plane will go with one engine. So I thought, that's okay."

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."


Am I crazy or correct in saying that no 737 can begin "dumping fuel"?

During my apprenticeship I have witnessed how a group of mechanics tried to install an engine on a 737-200 f*cked up. The problem was that everybody thought that he was in charge and the 5 people pulled the hoists without any coordination. The result was that the fwd R/H conebolt snagged when it was supposed to enter the hole and got stressed in a direction it was not designed for. One mechanic wanted to sweep everything under the carpet and continue with the installation as if nothing had happened, but the others were more intelligent and insisted that the supect cone bolt should be removed and brought to the NDT department for testing. The result was that it had been cracked by the force acting in the wrong direction and needed replacement. Good that they insisted on checking the bolt!

Stupid talk by somebody without a clue about aircraft maintenance and operation.

OMG! The plane almost crashed!

Seriously though. I was alerted to this via CNN's story. The 732 doesn't even have facilities to dump fuel... the article specifically says that the plane dumped fuel and "came in very slow". While this appears to be a catastrophic failure, this kind of stuff really does happen fairly regularly (eg. the Kalitta flight into Lake Michigan, and a couple others I'm thinking of but can't name...)

Again, media overhype.

I would have thought there were far more safety measures to ensure engines don't just fall off.

Actually, the safety feature is that the engine can fall off in abnormal situations.

It is a lot better than having the wing break apart and the entire aircraft crash.

You are correct that an engine that falls off could hurt or kill someone (or even a few people) - not to mention cause property damage.

That must be balanced by the result where the engine would not break off - and the entire plane would crash. A lot more people would get hurt and killed - and a lot more property damage would result.

Sometimes - having an engine fall off is a good thing. Note that the aircraft managed to do an adequate take off and fly quite well without the missing engine. Another safety feature most people never think about.

Of course, having an engine fall off due to poor maintenance practices is not the best for your image.

The article claims a foreign object. If true - then the safety features worked in this case.

You're 100% correct, and the media/tabloids are 100% incorrect:
