## Discrepancy

(CAN) EN-ROUTE, THE CREW OBSERVED A LOSS OF OIL PRESSURE. THE ENGINE WAS SECURED AND AN UNEVENTFUL LANDING WAS MADE. EXAMINATION OF THE ENGINE REVEALED THAT A PLUG IN THE STARTER GEAR SHAFT ASSEMBLY WAS DISLODGED, SUCH THAT PRESSURE OIL COULD ESCAPE THE ENGINE. FURTHER EXAMINATION SHOWED THAT THE PLUG HAD NOT BEEN ADEQUATELY SWAGED INTO THE BORE OF THE GEAR SHAFT. OTHER OPERATORS WHO HAVE GEAR SHAFTS FROM THE SAME PROCESS BATCH OF GEAR SHAFTS HAVE BEEN ADVISED AND THEIR GEAR SHAFTS ARE BEING RE-INSPECTED TO CONFIRM ADEQUATE SWAGING OF THE PLUG.
