The Story: This was a competitive governement bid that Maxcraft submitted and was awarded for at least one PC-12 upgrade but potentially more of the RCMP’s fleet. The work involved substantial integration efforts with existing avionics including radar systems, auto pilot, TCAS/TAWS systems, RMI’s, CDI’s, DME, Air Data Computers, etc. Maxcraft also was responsible to create the certification documents and have Transport Canada issue approvals via a Supplemental Type Certificate (STC). Maxcraft also carried out the necessary steps required to obtain Transport Canada Approval to remove the following Autopilot Limitation included in the Pilatus PC-12 POH that the autopilot must be disengaged, when the airplane is below 1000 ft AGL. The system is now approved for autopilot coupled approaches to 200 feet AGL .


As well the contract stipulated we had a promised short downtime and we are happy to say the aircraft departed on schedule from Maxcraft’s hangar. We look forward to seeing more of RCMP’s PC-12 fleet in our hangar soon.
