Hey guys,

I got curious after watching that Taiwanese air crash. Aside from feeling horrible for the victims and my condolences for the dead and injured...I started to wonder about the reliability of the Pratt & Whitney engines on the aircraft.

I came across the attached report doing a Google Search.
 
ATR Crash Reports

I did a bit of checking today and in addition to the engine problems, it apears the ATR-72 is extremely sensitive to icing conditions. at least 2 crashes directly attributed to icing, and 3 others to "weather related".

Update to Crash report

Rami,

I think you're right. Digging a bit, there seems to be a problem with the turbine blades in Stage 1 of the PW100-127 engine.

Heading over to PPrune to see what they are saying on the boards there.

Steve,

I'd rather be wrong...the pattern just jumped out at me for some reason.

Wayland,

I heard this morning that BOTH engines may have flamed out? :jawdrop:
 
ATR Crash Reports

Rami,

I thought at the time while viewing the video both props wern't turning correctly, but I figured it was just the lo-res dash cams.

Someone on PPRuNe noted the same fact. It's certainly possible. IIRC the left engine is the critical engine, for whatever reason.

Very scary.

We always confirm the engine prior to moving any power lever, it's forced into our heads from day 1 of ME training. There is no real reason to even touch them as long as the autofx does it's job.
