Leveraging Commercial Best Practices 3

◼ Two types of analytics to enable CBM+

◼ Reliability

◼ Using historical data and current MIS write-ups to enable data

driven decisions through component failure forecasting

◼ Predictive

◼ Using on board sensors and algorithms to identify degraded

components or systems

CBM+ Successes to Date

• C-5M Early Detection of Primary

Heat Exchanger Outlet Temp

Sensor

• Replacement of faulty sensor

• Alleviates eventual costly air exit

door failure…avoidance of over

$250K+ per occurrence

• B-1B Early Identification of Fuel

Migration

• Targeted troubleshooting greatly

reduces maintenance & engineering

manhours

• Avoids “nose-up” damage across

fleet…avoidance of over 1,000 hours

per occurrence

CBM+ is the New Business Model 8
