Cfm-56 In Flight Failure On AF A340

Wed Feb 28, 2001 8:41 pm

Hi
I've read in "le parisien" (the article is in french), that a cfm-56 blew out after take-off during climb on the A340 linking DAKAR to CDG
so,these engines which everybody say are so sophisticated and reliable happen to blow out sometimes...
now what would happen when an AA or DL 777 will loose an engine flying "the polar route 2" ???

Airbus should have put on the A340-200/300 stronger wings to hold either the P&W 2000 or RR RB211 series with 40,000lbs thrust instead of those small GE/SNECMA 34,000lb CFM56-5C4 engines.

They will divert to the nearest alternate airport and land. ETOPS criteria submit airlines to great trouble and expense to nearly guarantee that when a twin loses an engine it will be able to land safely.

And the engines _are_ sophisticated and reliable. Incredibly so ... most pilots will not experience an engine failure during their career. Reliable and invincible have quite distinct definitions, and no one is claiming that the latter applies to jet engines.

hi
I'm not dumb enough to mix the distinct definitions of reliable and invincible,thank you!
I'm fully aware of the procedures in case of an engine failure on an etop plane,but that's exactly my point:have you seen the fabulous airports of diversion on the polar route 2 ??
AA and DL executives have been working on this etop thing on the polar route 2 for a while and their conclusions aren't so clear cut...
lots of voices raise to say it would be more clever to fly a 4 engine plane on the route in order to avoid one day or another a flight to divert to a frozen and lost in the middle of nowhere north-eastern russia airport
