Here's the article:
Colombia's Avianca grounds four Pratt & Whitney-engined Fokkers | Reuters (http://www.reuters.com/article/2014/02/03/avianca-prattwhitney-idUSL2N0L81JG20140203)

Anyone has hear the reason for this - or has any more information ?'thanks

I think this paragraph in the article might have what you're looking for:

Disruption to Avianca's flight schedule will be less than one percent of available seats because it would use alternative planes on those routes until the cause of the fault is established, the company said.

Any idea as to problems with Torque problems arrising from the EECs or PCUs?
