Congratulations, Boeing! 
The initial 767s completed their first year in service on September 8, 1983, setting a new standard once again for quality and reliability. 
The reason for our belated greetings: The reliability figures are now complete for the fleet's first year. Abex electric motor driven hydraulic pumps achieved a mean time between failure of 110,576 hours; Abex servovalves in the flight control system logged 663,456 hours without a single failure. 
A remarkable performance by the aircraft. A remarkable performance by the pumps and valves. 
We weren't really surprised: Boeing's reliability is contagious. For Abex, it was a piece of cake.
