Wow, that's a lot.
Not as many as CRJ-100 and CRJ-200, though. See
"Transport Canada addresses frequent flaps problems of CRJ-200s".
So, what does it means?
Could it be that flaps problems are cited more often by the news because they may lead to an emergency landing, thus the passengers and news are all aware that there's an issue with the flight?
Could it be a design flaw?
Could it be the cold weather?
Could it be the operators?
What is the failure/cicles ratio?
So, what does it means?
It means that without more information, it is impossible to formulate a theory, and we're left only with F.U.D.
