Pilot reports pitch forces on a cessna ce-750 aircraft higher than normal when airborne. Although concerned about being called into office for making a repeat write-up; pilot notes that during landing roll when thrust reversers were deployed and with normal heavy nose down push on the yoke; the nose wheels rose off the ground. Maintenance believes left elevator is malfunctioning and not sending any type of EICAS message due to a possible electrical ground.

Narrative:
Pitch forces were higher than normal while airborne. During all three days of flying the plane. It had been written up two times before. Once 'ops checks good' and once for a relay change. The reason I wrote it up while in fear of being called in for a bad write up; was during landing roll when thrust reversers were deployed the nose wheels rose up off the ground with my normal heavy nose down push on the yoke. That deeply concerned me.now; after following our maintenance program aircraft information for a few days of trouble shooting; I'm more concerned that technicians think the left elevator is malfunctioning and not sending any type of EICAS message due to a possible ground. I also read that the problem may have started after a service bulletin had been accomplished. I'm worried that this is an issue on other ce-750 as I think I have encountered heavy pitch forces on other planes in the fleet. Recommend to advise operations and maintenance to have pilots report their suspicions of this problem. And or have maintenance check the elevator during service checks.
