Industry-leading improvements to the Boeing 777 scheduled maintenance program reduce maintenance by more than 400 labor-hours per airplane per year and give airlines one more day of service annually for each 777 in their fleet. Using industry averages, the increased time between certain maintenance tasks and increased revenue opportunity add more than $100,000 in annual value to each 777 in an airline's fleet. The new program includes extending the maintenance inspection interval for zonal tasks, involving such areas as doors, fuselage compartments, struts, and flight controls, from 25 to 37 months.
