I believe Mr. Coffman has hit the nail on the head! The FAA's response to the AD comment clearly states that RR IO-360's are flying on FAA-certified aircraft, and with the FAA's implied blessing!
If I'm reading the tea leaves correctly, the issue the FAA has is NOT that the engines are RR, but that they have not had the VAR crank AD applied? So it would follow logically that if a RR IO-360 had the VAR crank AD complied (and any other that is applicable), it would be acceptable to the Administrator???
