Honda Jet pilot reported a loss of elevator control authority due to a pitch trim fault. Trim fault occurred after takeoff and crew landed successfully after disconnecting it. Post flight troubleshooting of cycling power did not clear the indicated fault message.
Synopsis
Honda Jet pilot reported a loss of elevator control authority due to a pitch trim fault. Trim fault occurred after takeoff and crew landed successfully after disconnecting it. Post flight troubleshooting of cycling power did not clear the indicated fault message.
Narrative
Pitch Trim Fault - Reduced Elevator AuthorityOn departure from runway XX at ZZZ all seemed normal after take off. As we began to raise the nose into the FD (Flight Director); there was significantly more back elevator pressure than normal on the yoke. As we began to increase forward elevator pressure and trim it was obvious immediately the trim was not responding and the aircraft continued to pitch up. As the pitch attitude began to pass through 10degs; quickly approaching 15deg; there was no improvement in pitch control and we had limited remaining forward yoke travel. We immediately held down AFCS (Automatic Flight Control System) button to disengage the autopilot and servos; reduced throttle to slow down and get the nose down in order to regain forward elevator authority.Once we regained control authority we promptly ran the QRH checklists; [advised ATC] and chose to land at the location discussed during our departure brief (ZZZ1).ATC gave us vectors for the ILS [runway] XXL at ZZZ1. We flew a stabilized approach to landing without issue. After deplaning; we cycled the power and the pitch trim fault CAS (Crew Alerting System) message remained.
