## Discrepancy

Crew reported a pitch trim fail indication inflight. The aircraft returned to IAH without further incident. A reset of the system was performed along with an operational check of the stab trim. The aircraft was returned to service. The problem reocurred and returned to IAH. Maintenance removed and replaced the Horizontal Stabilizer Control Unit. The aircraft operationally checked good and was returned to service.
