Whats wrong with this very 763 CC-CXH???

Christmas Eve Engine Nr1 Shut Down in Flight, emergency landing at Faro:

Incident: LAN B763 over Atlantic on Dec 24th 2015, engine failure (http://avherald.com/h?article=4914c422&opt=0)

After new years...Engine Nr1 shut down in flight, emergency landing at Guayaquil:

Incident: LAN Ecuador B763 at Guayaquil on Jan 4th 2016, engine shut down in flight (http://avherald.com/h?article=491da5f2&opt=0)

Intriguing - but what it really means depends on whether the engine was replaced after the first incident, or simply serviced, checked, and cleared back to flight status.

And what the exact problem was in the first instance (the second instance is reported - low OP and vibrations).

Was it one engine that failed twice, or two engines on the same pylon of the same aircraft, that each failed once.

Appears to have spent 5-6 days (holiday weekend intervening) in Faro before continuing to Madrid on 12/30. Ferry flight (? - no flight number - 12/30) back to Lima. Then several revenue flights before the second incident.

An aircraft has a couple of technical issues 10 days apart and it excites you? You may find it's far more common than you think. It happens. It's not all that unusual for airlines to experience a host of tech issues on one particular aircraft whilst the remainder of the fleet plod on without problems for years. All go through the same maintenance procedures. Just one of those things.

On an Etops aircraft an engine failure is rare. To have two failures on the same engine within 10 days is quite extraordinary. It indeed beggars the question what had been done after the first one.

Yes, it would be.

If it was the same engine.

It's not extraordainary if it's the same engine and they missed something on the initial fix. Extraordainary would be a different engine on the same aircraft with an issue unrelated to the first failure.

No, it does not excites me...it intrigues me.

agreed it would be!

Hotel Tango, you'd be right enough if it was a minor defect, but something that causes an engine failure or shutdown should not be recurring so soon, especially on an ETOPS flight.

I can confirm it was the same engine - they changed some components after the first shutdown, but apparently not the correct ones.


Not sure I'm allowed to say much more...:rolleyes:

With ultra-reliable systems (generally and not just aircraft), following a failure the most likely subsequent problem will be "same system" and "very soon". Usually for the reasons described by tdracer.

This does not necessarily reflect on the diligence of the maintenance crew. If a problem cannot be reproduced consistently under test, and if no definitively defective components can be identified then how is one sure that the repair is complete?

I'd imagine there's also infant mortality of replaced components.
