Narrative:
On jan/mon/04, I installed a starter-generator on the left engine of aircraft X. The inoperative starter-generator had been removed. I verified the customer supplied part was the proper part by part number identify. The unit was installed and the mounting clamps torqued. The 4 hoses that were removed, in order for the removal and installation of the starter-generator, were then reinstalled. The hoses all had identify tags for reinstallation purposes. The engine was washed with solvent and the starter momentarily contacted to insure the starter operation. Flight line maintenance control was then contacted and informed that ZZZ maintenance had no one qualified to run the engine and check the operation of the starter-generator and to check for any oil leaks. We were informed that the flight crew was on the way. The crew did not show before normal business hours were over. I was not contacted after business hours to check the engine for leaks after run-up. No further action was taken. The shop chief inspector was asked to do a final inspection and did. All shop management and flight line maintenance were advised of the situation. Callback conversation with reporter revealed the following information: the reporter stated the cause of the oil loss cannot be revealed due to instructions of the lawyer handling the case. The reporter said no other details of the incident would be discussed other than the engine lost oil pressure and quantity.
