Methods and systems for centrally managed maintenance program for aircraft fleets
First Claim
1. A system for centralized maintenance management of a fleet of aircraft by a business entity for a plurality of customers operating the fleet of aircraft, said system comprising:
- a data acquisition subsystem configured to collect operational performance data and maintenance data from at least one aircraft in the fleet;
a monitoring subsystem configured to receive the collected operational performance data and maintenance data for a plurality of aircraft in the fleet and to determine a range of acceptable values of performance parameters associated with the collected data and based on the collected data from those aircraft having similar operating histories;
an analyzer subsystem configured to receive the determined ranges and the collected data, said analyzer further configured to determine which of the collected data include values outside the determined ranges and determine at least one of aircraft systems, maintenance tasks, and environmental factors that influence the values of the collected data; and
a maintenance task database including information relating to maintenance tasks performed on aircraft in the fleet and intervals of performance of the maintenance tasks wherein at least one of a maintenance requirement and an interval between maintenance actions is modified to facilitate reducing the number of performance parameters values that are outside the range of acceptable values during future operation of the aircraft.

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.

11. A method of managing maintenance of fleet vehicles for multiple customers using a system including a processor, said method comprising:
-
collecting performance data and maintenance information related to the operation of the vehicles; storing the performance data and maintenance information in a database; accessing the performance data and maintenance information at an engineering facility; determining acceptable ranges of values of the performance data and maintenance information and acceptable trends of the performance data and maintenance information using the stored performance data and maintenance information; analyzing, by the processor, the stored data for values and trends that exceed the determined acceptable ranges of values and acceptable trends of the performance data and maintenance information; and modifying an interval between maintenance actions to facilitate reducing the number of performance data and maintenance information that are outside the range of acceptable values during future operation of the vehicles. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A system for centralized maintenance management of a fleet of aircraft by a business entity for a plurality of customers operating the fleet of aircraft, said system comprising:
-
a monitoring subsystem configured to receive operational performance data and maintenance data collected for a plurality of aircraft in the fleet; an analyzer subsystem configured to receive the collected data, determine which of the collected data include values outside of one or more predetermined ranges of acceptable values of performance parameters associated with the collected data, and analyze at least a portion of the collected data using at least one of trend analysis, root cause analysis, and engineering analysis; and a maintenance task database including information relating to maintenance tasks performed on aircraft in the fleet and intervals of performance of the maintenance tasks wherein at least one of a maintenance requirement and an interval between maintenance actions is modified to facilitate reducing the number of performance parameters values that are outside the predetermined ranges of acceptable values during future operation of the aircraft. - View Dependent Claims (20)
