HOW ISDP WORKS
All of the companies participating in the ISDP gather similar airplane, component, and system reliability data (see fig. 2). A "Data Dictionary" containing standardized record layouts for each data subject enables data from the different companies to be exchanged and stored in a common format in the database.
ISDP DATA PROVIDED BY AIRLINES AND SUPPLIERS
|DATA PROVIDED BY AIRLINES||DATA PROVIDED BY SUPPLIERS|
|Aircraft hours and landings
Aircraft events (schedule interruptions)
Line replaceable unit removals
Shop findings (component repair)

Each month, suppliers and airlines send raw data for each pertinent data subject to Boeing for processing. Boeing then screens the suppliers' and airlines' files for errors, places the processed data into an NCR Corporation Teradata enterprise data warehouse at Boeing, and stores it in a relational database.
ISDP's Data Dictionary, which defines data exchange record layout and data element definitions, was used as the baseline by the Air Transport Association (ATA) in the creation of a new SPEC2000 chapter: Chapter 11, Reliability Data Collection/Exchange Standard. Chapter 11 of the SPEC2000 e-business system is the industry standard for reliability data collection and exchange using an extensible markup language (XML) format.
Access to the processed data is provided through the Web portal MyBoeingFleet.com, using a Boeing-developed Web-based data extraction and reporting tool called Fleet Reliability Statistics, and BI Query, an enterprise-strength query and reporting application from Open Text Corporation. The data can also be accessed using any software that has an open database connectivity interface compatible with Teradata.
Standard reports are available for management visibility and trend analyses. These reports — which can be accessed by operators through MyBoeingFleet.com and by suppliers through the Web portal Boeing Partners Network — contain monthly flight hours and landings, schedule interruptions, line maintenance action rates, removal rates, failure rates, shop findings, component rejection rates, and other data, all of which are critical in monitoring the reliability performance of the airplane fleet (see fig. 3).
In addition to line maintenance data, ISDP is now able to collect base maintenance records, such as scheduled maintenance and service bulletin incorporation. This additional data will provide complete visibility to all aspects of maintenance activities and enable Boeing engineers to become more proactive. For example, Boeing maintenance program engineers are planning to use this comprehensive data to optimize the scheduled maintenance requirements for the Boeing fleet. This would enhance safety and reliability of commercial airplanes, improve airplane availability, and achieve maintenance cost efficiencies.
Prior to ISDP, most airlines provided only flight hour and schedule interruption data, which limited the support Boeing could provide. The additional logbook and removal data provided through participation in this program allows more complete support for member airlines and the entire fleet.
