You're right that there will be much to remanufacture - engine bearers, wire looms, control rods, mounts, etc... However, from what I could see the fire did not appear to go into the wing and damage the all important wing spar. I recall that LF363 was almost completely burned at RAF Wittering in 1991 and she was lovingly rebuilt, so I am very confident that PA474 will fly again.
By the way, I saw the old girl in the flesh shortly after the fire and she is definitely still standing proud on both legs - as others have said, well done to the crew and the fire crew for saving her.
