Narrative:
I was working in the pratt-whitney (pw) engine stall when I was approached by the pw-2000 manager. He said he needed to speak to me about something and he went to get my supervisor. At that time I went and found my union shop steward. We both went to the supervisor's office and met with the manager and supervisor. They both informed us there was a [company] investigation being conducted on a pw-2000 engine which I had worked on over a year ago. It was explained that the engine was found to have very high oil consumption and after 1;400 hours of service [the engine] had been removed from the aircraft and taken out of service. Upon closer inspection of the number 5 bearing compartment; it was discovered that the number 5 bearing cover plate was not installed. The manager informed me that I was the mechanic who signed-off the job card.
