Narrative:
I was notified by the company that aircraft X had to shut down due to low oil pressure on the engine that I worked on #2. I followed the maintenance manual and 3 sets of eyes checked it for leaks after 2 sets of engine runs. Callback conversation with reporter revealed the following information: the reporter stated the pump was replaced and leak checked twice per the maintenance manual pump replacement procedure. The reporter said the crew shut down the right engine in-flight due to loss of oil pressure. The reporter stated this engine was a high oil consumption engine and replacing the scavenge pump was for troubleshooting. The reporter said the company has released no findings on the engine oil pressure failure.
