Fan blade (FRP)catastrophic failure and drive shaft bent and broke down in cooling tower.
(OP)
1 fan blade(frp) in A336" diameter fan assembly has been found in catastrophic failure condition and drive shaft(metal) also found in bent and broken condition on ground.
What are the possible root causes??

There isn’t even a picture of the ground it fell on, however how about the Op answer my problem.
I have a 10” diameter frying pan and the handle just fell off what might be the possible causes?

Politicians like to panic, they need activity. It is their substitute for achievement.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

Sorry. I couldn't help jumping on.

op - do you have a picture of the failed parts? That would be a good start.

I'm now legitimately wondering if there is a failing VFD that is feeding a really poor quality waveform into the motor and causing the vibration. I can see that leading to fatigue failure of the blade and the imbalance then bending the shaft.

Drive shaft also has been replaced with coupling and rebalancing has been performed also. But no effect on vibration."

If so, the workmanship of the repairs AND the possibility of defective new parts must be tossed into the more-than-half-full bucket of possible "root causes".
Seriously, the broken parts and all mating parts and systems have critically important stories to tell.
They speak in pictures, not words (spoken or written).

You silly person. It had to have been space aliens!
