  • Methods and systems for centrally managed maintenance program for aircraft fleets
    Patent number: 8694196
    Abstract: Methods and systems for managing maintenance of a fleet of aircraft are provided. The method includes collecting data from at least one aircraft in each of the fleets related to the operation of the aircraft, determining a range of acceptable values of performance parameters associated with the collected data and based on the collected data, analyzing the collected data having values outside the range of acceptable values, and modifying at least one of a maintenance requirement and an interval between maintenance actions to facilitate reducing the number of performance parameters values that are outside the range of acceptable values during future operation of the aircraft.
    Type: Grant
    Filed: December 12, 2012
    Date of Patent: April 8, 2014
    Assignee: The Boeing Company
    Inventors: Farshad T. Doulatshahi, Blake Gibbons, Charles K. Bautz, Jr., Anbessie A. Yitbarek

  • Statistical analysis for maintenance optimization
    Patent number: 8117007
    Abstract: A computer implemented method, apparatus, and computer program product for identifying an interval for performing a maintenance task. The process retrieves scheduled maintenance data and un-scheduled in-service maintenance data for a given apparatus type. The process maps the un-scheduled in-service maintenance data to the scheduled maintenance data for the given apparatus type to form mapped maintenance data. The process performs a statistical analysis on the mapped maintenance data. The process identifies an optimal interval for performing the maintenance task based on a result of the statistical analysis to form a recommended maintenance interval.
