Please note that in most cases an aftermarket air conditioner does not change the aircraft cowling, therefore the “w/o air conditioning” spinner assembly (C-3567-9P) would be needed when ordering.

On models E55 and E55A, factory air conditioned models with long nacelles requiring the longer J3YF hub are not compatible with factory installed alcohol anti-ice systems. The propeller anti-ice system must be labeled “inop” at propeller conversion installation. Hartzell does not offer a compatible alcohol anti-ice system for these aircraft at this time.
