Narrative:
I, as a lead mechanic, was recording engine oil and aircraft airworthiness only. On job card, items were stamped off by a mechanic as accomplished on aircraft DC9. Date of incident dec xx 1996, XA30 am. Callback conversation with reporter revealed the following information: I was responsible for posting the logbook and clearing the job cards and all jobs listed were in order and signed off. The aircraft was dispatched and on arrival at the next station the crew requested oil service on #1 engine. When the servicing mechanic opened the oil service, it was discovered the oil cap was not properly installed and locked. This allowed the loss of oil from #1 engine. The engine was a P&west JT8D-9. The reporter states that the FAA has made no contact.
