A United Boeing 767-400, registration N67058 performing flight UA-42 from Washington Dulles,DC (USA) to Rome Fiumicino (Italy) with 232 people on board, was enroute at FL330 about 60nm east of Halifax when the crew received indication of a low hydraulic quantity on the center system. The crew worked the related checklists and decided to divert to Newark,NJ (USA) where the aircraft landed safely about 1:45 hours later.

A replacement Boeing 767-400 registration N59053 reached Rome with a delay of 6.5 hours.

A passenger reported that the captain had invited the passengers to listen to channel 9 carrying the communication between aircraft and ATC. The aircraft was somewhere in the vicinity of St. John's when the channel was shut down. The captain announced that one of the three hydraulic systems had failed, they were fine to fly on the other two systems, however, did not want to cross the Atlantic that way and were diverting to Newark for an aircraft change. Just before landing the captain advised emergency services would receive the aircraft to check whether any fluids were leaking from the aircraft. The aircraft was shut down and towed to the apron, where a replacement aircraft was already waiting. A new flight crew continued the flight, while the previous cabin crew boarded the new aircraft and continued to Rome.

The Canadian TSB reported maintenance replaced the differential pressure indicator and the associated o-rings on the center filter module. A leak check showed no further fault.
