In all likelyhood it probably was P**** E**** most accidents are. I know the aircraft was very well maintained until its sale last october so certainly no bag of nails. That doesnt preclude some failure because even well maintained aircraft fail.
A citation doesnt go down on a simple one engine out so there has to be some other factor mechanical or human which added to this.
The important thing is that whatever the cause the findings are conclusive so that we other pilots can avoid a simular situation.
