Incident at 49 00 N 050 00 W


1996-12-30: The B767 was approximately 150 NM north east of St. John's, Nfld. enroute from London, England when the crew requested a diversion to Halifax due to a minor mechanical problem (The circuit breaker for the left engine nacelle vent valve had tripped and the left engine "Low oil pressure" light had illuminated even though the pressure indication on the gauge was normal). ATC cleared the aircraft to Halifax where it landed without further incident. Once the aircraft had landed, the descrepancies had to be either rectified or deferred under the MEL by qualified maintenance personnel, before it could depart again. Since the qualified personnel were only available in Halifax and not in St. John's the operational decision was made to divert to Halifax. TSB closed.
