Overview
• Evolution of Scheduled Maintenance
• HMMS as a more efficient and more effective way of accomplishing scheduled maintenance

WHY DO WE DO SCHEDULED MAINTENANCE ?
• To permit an item to continue to do what it supposed to do

Constant Evolutionary Process
• Early days of aviation - Fly-Fix-Fly
• Post WW2 era – Overhaul Everything
• Post Prop era – Overhaul Some Items
• Post Wide Body era – Reliability Centered Maint. and MSG -1, 2, and 3
• Modern era – Optimize Maintenance Requirements

The Continuing Evolution
• Fixed interval scheduled maintenance programs have been a scheduled maintenance mainstay for over 70 years.
• Aircraft Health Management and Monitoring Systems (HMMS) are the maintenance technology of the future.
• These systems are being envisioned for new generation aircraft such as the very light jets, Boeing’s Model 787, and the Airbus Company’s A380.

How HMMS Does It
• HMMS incorporates innovative, imbedded sensors, to provide continual real-time aircraft systems and structures health assessments
• HMMS incorporates on-board state-of-the-art structural and systems integrity computer programs with decision making capabilities

What HMMS Does• HMMS evaluates all flight-critical structures for
integrity as part of an automated preflight checklist• HMMS provides the pilot with visual displays of the
health of all systems prior to takeoff• HMMS displays any in-flight change in the health of
the aircraft along with recommended action or automatically takes an action
• HMMS automatically updates the life history of the aircraft so that accurate structural integrity assessments can be made

The Paradigm Shift
• HMMS is a different way of doing the same thing
• HMMS does not eliminate maintenance• HMMS embodies a shift to automatic,
continuous, real time inspection activity rather than intermittent scheduled activity

Current HMMS Usage
• HMMS has been implemented on helicopters for years
• HMMS has been incorporated in auto, marine, and industrial applications.
• This is the CHECK ENGINE LIGHT• This is the General Motors ONSTAR System

More HMMS Usage
• Military airborne target drones • Remotely piloted airborne vehicles• Space satellites• Hubble Telescope

What the Future Holds
• HMMS can provide continuous, real time monitoring of most of an aircraft structures and systems
• HMMS can detect damage or deterioration of systems or structure without human intervention
• HMMS can utilize an automatic downlink to notify ground stations of required maintenance

What the Future Holds
• Boeing 787 Advanced Technology:
– “An open architecture will be at the heart of the 787's systems, which will be more simplified than today's airplanes and offer increased functionality. For example, the team is looking at incorporating health-monitoring systems that will allow the airplane to self-monitor and report maintenance requirements to ground-based computer systems.”
