NOTES:
Please note that in most cases an after market air conditioner does not change the aircraft cowling, therefore the “w/o air conditioning” spinner assembly (C-3567-1P) would be needed when ordering.

Electric De-icer Kit approved on s/n TH-1231 and later only. Aircraft with s/n TH-1230 and before must disengage any existing electric de-ice system.

Aircraft eligible for electric de-ice system (s/n TH-1231 and later) require airframe de-ice kit when replacing McCauley propellers only.
