The MD-90 uses the same engine as is offered for the A320 family of aircraft; the V2500, albeit a derated version of it.
My question is when the engine is mounted on an MD-90 do they use the same attatchments? i.e. Is the engine on an MD-90 flying 90 degrees rotated compared to the mounting position on an A320 family aircraft? Does this affect the equipment at all?
