A lead aircraft maintenance technician (amt) was informed he had not tighten one of the bolts that secure the tail rotor control tube on a bell-206L helicopter after replacing the aft evaporator blower motor. Technician noted that pressure from supervisors to get the job done and the use of pilots to look over major maintenance work accomplished by mechanics were contributors.

Narrative:
I removed the aft evaporator blower motor. To gain access; the tail rotor control tube had to be removed. When the job was finished I asked a pilot to come and look the job over. We both missed the bolt that I failed to tighten on the tail rotor control tube. We operate a 24/7 helicopter emergency medical service (hems) operation and are on call 24/5. I feel that pressure from supervisors to get the job done so we can capture flights affected my performance. I feel that the pilots are not adequately trained to look over major maintenance such as flight controls. I removed the aft evaporator blower motor.
