PC12 Pilot reported shortly after take-off; receiving an Amber 'Flaps' Message followed by an Amber 'Pusher' Message; a Blue 'Pusher Safe Mode' Message; and an Amber Flap Position Indicator that was not moving and was stuck at roughly the 14-degree position. The pilot performed an air turn back and precautionary landing at departure airport.

Narrative

On Day 0; I; Person A; performed all preflight inspections for a flight that was supposed to go from ZZZ to ZZZ1 at XA00. The following events are what took place leading up to the event. Upon arriving at ZZZ the ceilings were broken at 1600; with light winds and good visibility. Getting to the aircraft; I first did my preflight walk around following the checklist and everything was normal with nothing alarming. Following the preflight; I turned on the batteries and checked the fuel quantities and made sure the interior preflight inspection was done thoroughly and by the checklist. Everything was normal so I called ZZZ Clearance and picked up my flight plan to ZZZ1. The flight plan was radar vectors; ZZZZZ Departure with the ZZZ2 transition; followed by the ZZZZZ1 Arrival with ZZZZZ1 as the transition into ZZZ3 Airspace. By this time; the passengers were arriving; and I helped them load their bags which consisted of just a couple hanging bags and small duffel bags. Once they were loaded in and buckled up; the start procedure was normal with no negative indications across any systems. Before taxiing; I performed the Pusher Test (Flaps 15 and torque above 5 PSI) which was completed with no failures. After this; I began taxiing out to Runway XX and called Clearance to report that I was number one; holding short of Runway XX. They gave me a right turn to heading 220 and up to 2000 ft. and released me for departure. I switched to CTAF and taxied onto Runway XX. At this point; all checklists had been completed; there were no cautions; warnings; or advisories indicated so I proceeded with a normal take-off. After leaving the ground there was light turbulence. I turned the lights off; raised the gear; turned the yaw dampener on; and moved the flap lever to the up position coming through about 300 ft. AGL. Shortly after; I received an Amber 'Flaps' Message followed by an Amber 'Pusher' Message; a Blue 'Pusher Safe Mode' Message; and an Amber Flap Position Indicator that was not moving and was stuck at roughly the 14-degree position. The aircraft was still controllable; and I proceeded to my climb to my assigned altitude and turn right to my assigned heading of 220. At roughly 1000 ft. I switched from the CTAF to ZZZ Departure and they told me to continue my climb to 4000 ft. and remain on a heading of 220. I complied and at this point I was using the QRH to try to diagnose the problem. Once I read the QRH; step 2 was to land as soon as practical. Reading this; I [requested priority handling] with ZZZ Departure because I did not want the problem to get worse. I felt that for the safety of my passengers; other aircraft; and myself; it was best to get priority to get on the ground as quickly as possible in such a busy airspace. After coordinating this with Departure; I was above the broken cloud layer and needed to load the RNAV approach back into Runway XX at ZZZ. The Controller then gave me vectors to the approach and a successful approach was carried out with a landing speed approximately 10 kts. higher than the AOA Dynamic Speed Bug. I then taxied to the ramp; shut down the engine and deboarded my passengers.
