Synopsis

Corporate flight crew reported aileron failure on climbout caused a temporary loss of control.

Narrative

As we departed from ZZZ yesterday coming back to the ranch we lost all navigation references along with heading and altitude references at around 500 feet AGL. As we were working through the problem our altimeter came back and we were climbing through our assigned altitude. As the PF went to level the airplane off; we received an Elevator Gear Warning message. The airplane continued a climb and started rolling to the right. Person A had yoke in a descent position as the climb was still happening. As the PF had near full deflection on the ailerons; I looked out the window and the ailerons were not moving at all. I then took control of the aircraft and moved the controls around and eventually everything started back working and we regained control of the aircraft. The heading and navigation never came back though. We [requested assistance] and continued to the ranch landing safely. The controls after the incident were much heavier than normal with a strong pulsation coming through the yoke anytime you added pressure to them.Aircraft systems malfunction.

Second reporter narrative

On climb out leaving ZZZ we were given climb 2000 and turn 330. Around 400/500 feet we lost all navigational information on displays both right and left side. I was the flying pilot I stopped the right hand turn using the mag compass. When I went to roll left to stop the turn the aircraft did not respond; also at this time I was pushing forward on the controls to stop the climb. This control input did not respond either. I had told the Captain that I had no control of the aircraft. The captain looked out his window to look at the aileron and then he [requested priority handling]. The aileron was parallel with the wing.At that time he took control of the aircraft. Note: At the time the Captain took control of the aircraft I had full left control input and was still turning. The pitch control was almost full forward. Shortly after the Captain took the controls they slowly returned to normal with the exception that he stated the controls were heavier and had a pulsation feedback in them. We landed safely at ZZZ1. Weather was clear. Maybe events are caused by the rudder system.
