Narrative:

I was notified that an agusta A119 helicopter was grounded by previous tour (shift) due to high inter turbine temperature (itt) of 805 C (celsius). In the early hours of the morning; the helicopter had just landed and engine was at idle RPM. Pilot was assigned with a new mission. When he was in transition from idle to maximum power; he noticed a rapid rise of temperature to 805 C and proceeded to shut down engine. These types of incidents had happened previously; but [were] not properly documented on the aircraft maintenance in-flight log.I proceeded to turn battery power on aircraft and noted that on edu (electronic display unit) #1; the itt was showing a temperature of 1277 C and needle was pointing at the maximum temperature of gauge. Helicopter had been grounded for about four hours. I de-cowled aircraft engine compartment area to gain access to its' wiring and components according to agusta-westland A119 koala maintenance manual. [I] also made available the use of pratt & whitney PT6 series engine maintenance manual (emm). After trouble shooting of system; engine trim compensator was removed and replaced with another trim compensator which was retrieved from the parts room. Did note that there was no paperwork with the unit; but continued with the installation according to the emm since we [are] suppose to have the paperwork required in our records office.at the end of my tour [shift]; which was late afternoon; did a [shift] turnover to the next platoon (crew). The next day; at approximately noon; continued with the trim compensator adjustment in accordance with the emm with my co-worker detective X. Since he was assigned to the parts room I asked him about the trim compensator paperwork; which he had no information of. [Before shift change] sergeant Y asked me what the [maintenance] turnover was. When I attempted to passe the information over to sergeant Y; he turned around and started a conversation with detective X; not paying attention to what was said. I left at the end of my tour (shift). The next day; when I returned to work I did notice that the helicopter was cowled; and the discrepancy was signed but no a & P certification number. I proceeded to ask detective Z about the paperwork for the trim compensator since he was assigned to the records office. He told me that he was going to look for it; since he did not have it readily available. Due to weather; the A119 koala helicopter did not fly on my tour. Paperwork was not showed to me since detective Z left early that morning and no one else had access to the information.the next day; I asked my immediate maintenance supervisor; sergeant a; about the paperwork for the trim compensator. His answer was that the turnover he received from lieutenant B was that it was returned to service. I explained to sergeant a my concern about the paperwork for the trim compensator unit that I had installed on the helicopter; since no document had been presented to me. [Approximately 20 minutes later]; sergeant a returned to the parts room where I was with other aircraft maintenance technicians (detectives/police officers) and told me that the previous information [about the helicopter returned to service] was told to him by a higher supervisor; also that I knew what to do and the ball was in my court.after he went home I proceeded to call detective Z; via cell phone and left him a message which he did not return. Proceeded to call detective X and asked him again about the documentation for the trim compensator and he replied that he was on his way to the city police department aviation unit. Since no documentation was presented to me to prove the airworthiness of the engine trim compensator; I told my immediate supervisor sergeant C; that the helicopter was grounded; pending proof of documentation to me; since I was the technician that had installed the trim compensator. Later; I was approached by lieutenant B and was asked to provide the discrepancies sheet where the trim compensator was noted to have been removed and replaced. I told lieutenant B that detective Z should have possession of such documents. I also told lieutenant B my concern about the documents that I have been requesting for the past few days.I signed out to go to lunch; when I returned from lunch I observed police department A119 koala helicopter taxing out for a flight. I approached my immediate supervisor pilot sergeant C; pilot sergeant D and pilot detective east; expressing my concerns again and that the aircraft should return to base. The A119 was returned to base after flying 0.2 hours by lieutenant B on a maintenance flight along with detective X. I was summoned by lieutenant B to report to the operations office where I was told that he had the documentation required and also I do not have the right to determine what aircraft is in; or out; of service; only he (lieutenant B) will make that determination. I was also told that I was relieved from the maintenance floor until a meeting with sergeant Y.had the meeting with lieutenant B; sergeant Y and detective east; where I was told that I had proceeded to intervene with the operation of the city police department aviation unit. Like I have done previous; I asked them to provide me with a standard operations procedures (SOP) by the city police department aviation unit and was told that there was none available at this time. As a city police detective specialist on the aviation unit I must follow all rules and regulations from the patrol guide; also I am bound and must follow federal aviation administration rules and regulations which are far/amt part 43; 65 and 91; to be able to perform maintenance; preventive maintenance or alterations on the bell 412 and agusta westland A119 koala helicopters for the city police department.
