In response to Elephant & Castle`s invitation to share factual information I suggest reference to Ulster Herald`s report of 12 February 2013, at the following web link.
Report into Cork plane crash delayed by Spanish documents
In particular to the following extract therefrom:
The investigation unit last year revealed problems with engine number two of the twin turboprop Fairchild Metroliner which could have caused an uneven thrust from the wings.
I trust this may sufficent to show that my comments were not mere speculation.
