Narrative:

I arrived with an a&P/ia that specializes in the cessna conquest ii airplane and garrett engines. We did some diagnostics and run-ups to determine and correct the problem that caused a loss of engine torque on the last flight in the airplane. The trouble could not be duplicated and it was the opinion of the a&P/ia that it was an intermittent problem with the fuel computer. At the advice of the a&P/ia; the fuel computers were taken off line and the aircraft was flown home in manual mode; which is permitted by the poh. It later dawned on me that we could have gotten a ferry permit for that flight but we didn't. At the time; I felt that the flight was safe but it seems that I could have; as a procedural issue; sought and gotten a ferry permit to ferry the airplane back to where that a&P/ia has a shop and more complete diagnostic equipment. There were no injuries or damage to anyone or anything.
