The article says "engine part", but the picture seems to suggest otherwise.

MSN News reporting
The 747, with 300 passengers on board, was on a flight from the capital's Mehrabad airport to Bandar Abbas in southern Iran when one of its engines crashed into a nearby field, forcing the jumbo to return and make an emergency landing.

Would it be a 742?

could have been a worse case scenario if the part's have hit the fuselage or the stabilizer with a full plane loaded
thanks all went well

The pilots were reading a.net during take-off and read your most favorite statement (the time of 4-holers is over) so - unlike many a.netters - they did not start discussing but immediately took action and discharged one engine ....  

Just kidding, yes, thankfully nobody was hurt.

Can anyone explain under which circumstances such a large part of the engine can fall off?

Of course, this gets into one of the serious problems the sanctions as to Iran can lead too. I suspect there is serious damage that will make it questionable about continued operation of this aircraft.

A Boeing 747-3B3 operated by Mahan Air returned to land at Tehran-Mehrabad Airport, Iran after it lost part of the no. 3 engine.
The rear, Low Pressure Turbine, section of the Generel Electric CF6-50E2 engine broke away and fell to the ground in the Eslamshahr area.

With sanctions being lifted on Iran..when is Iran likely to order from the big 2? I am guessing all these years of embargo has probably created a great bit of thirst for planes, among other things.

Engine 3 and 4 were both shut down - part of Engine 3 separated and Engine 4 was shut down due to an oil pressure warning.

Several uncontained CF6 engine failure are recorded.

A safety recommendation was issues by the NTSB in May 2010 :
http://www.ntsb.gov/safety/safety-recs/recletters/A-10-098-101.pdf

Despite that, an identical CF6-50E2 uncontained engine failure happened in Cairo, with HS-VAC, a former KLM 747-306M, operated by Phuket Airlines (leased to Saudia)

See : http://aviation-safety.net/database/record.php?id=20100717-0

And : http://www.baaa-acro.com/2010/archiv...shap-of-a-boeing-747-300-in-cairo/

HS-VAC, identical damage pattern

It's hard to say. Neither NTSB nor Boeing would have made any effort to share the information with Iran and if it required a new part Iran would not have been able to purchase it. I suspect the NTSB bulletin would have required a new part of some sort.

Next year.

As I've said many times on ANET, and received heat for it, aviation parts sanctions on Iran are a threat to both civilian passengers in the air and on the ground and violation of ICAO's charter promoting safe aviation. The US in particular is after Mahan Air because they fly into Syria and this event happened literally 1 day after a long expose promoting sanctions on them.

Wouldn't surprise me if CIA was actively sabotaging Mahan's frames. Yes, I know sounds like a conspiracy theory.

No, Iran can start using it's own metal to fly it's people around. If the country is so great, then develope a respectable aviation industry and stop using the assets of the West which it so hates. It is really simple. They do not have a right to Boeing jets or the spare parts to fly them. Done.

Sure, because what country wouldn't want to invest in a multi-billion dollar aviation industry without prior experience. After all, how hard can it be? It goes so easy for an experienced manufacturer like Boeing that their newest model was only delayed EIS by about 3 years. And it's so complex they can't even manufacture all the parts themselves so they outsource it to places all over the world. So yeah, really simple.

My thoughts exactly. Two others have also involved Iranian aircraft: the Iran Air event at ARN in January 2010 and Qeshm Air at IST earlier this year. Both were A300-605R with CF6 engines.

The mother of them all was the July 1989 United DC-10-10 crash landing at Sioux City, Iowa (IATA code SUX, perhaps pun intended). The UA flight involved the CF6 in the number 2 position.

A300-605R aircraft have CF6-80C series engines installed.
The CF6-80A/C engine is an advanced development of the earlier CF6-50 series engine, but despite superficial resemblance, it is a completely new engine with no interchangeable parts

The Mahan Air B747-300 has the older CF6-50E2 engine type installed.

CF6-50 series and the partly identical CF6-6 series are also installed at :

DC10-10 (CF6-6)
DC10-30 (CF6-50C, C2, C2B)
B747-100SR (CF6-45*), B747-200 (CF6-50E, E2), B747-300 (CF6-50E2)
All A300 series (CF6-50A, C, C2), except -600(R) series.

* CF6-45 is a derated CF6-50 engine.

Typically American attitude. If you endanger someone else's civilians over foreign policy then don't complain when I dunno they take your metal and fly into your civilian buildings? There is no requirement to deliver safety related parts but be prepared for the consequences and don't assume that it's just Iranians being killed. Eye for an Eye means you go blind too.

Lol       Iran is not nearly as bad a place as some would like you to think it is.
In all seriousness though, you do realize that if Iran bought new Boeing jets, it would be good for the American economy, right?

Really, taking the situation and justifying 9/11 with them is really not cool, and certainly has no place on A'Net.

Anyways, i'm glad to see the aircraft made it down safe and sound.

I mean he has to be basically crazy. They are actively talking about 400 orders and if you look at the internal and external travel rates its very high. They have around 3 million tourists per year which can easily double post sanctions.

Try that argument with Turkey or Dubai when one these bird sheds an engine over downtown and kills some royal family in their Bentley. "ITS YOUR FAULT, you let them land after all! and they decided to fly an unsafe plane!"

Yeah its the internet. This is the place for that. And I'm not justifying it but if you put innocent lives at risk over nebulous foreign policy goals, then you own the consequences.

Either way, I've always said, don't feed the hand that bites you. I'd actually give Airbus the coveted M word if they dumped US suppliers. I'd offer them a 25 year monopoly in exchange for punting US parts.

What an odd connection to make.

I guess you believe that us having sanctions justifies 9/11 type events, but I see it somewhat differently: You don't have a safe plane, don't fly it. Whether you agree or disagree with the sanctions is a separate issue. No one is holding a gun to their head and saying "Now go fly this unsafe aircraft over a city and see what happens".

Um, you folks are all aware it was Saudis who flew airplanes into your buildings right? The same Saudis Lockheed Martin is selling $11B worth of combat vessels to. The enemies of the Iranians. The whole anti-Iran agenda in the middle east is only benefitting the house of Saud and their business partners.
