Bell 407 HUMSMail to AA Sales Team



  • Automatic data acquisition for rotor track and balance reduces maintenance flights
  • Advance notice of degradations on dynamic components can turn unscheduled maintenance into scheduled maintenance
  • Catching problems early can reduce any collateral damage – i.e., less cost to repair
  • Acquisition and easy download of flight parameter data can support a Flight Data Monitoring (FDM) program for new Part 135 compliance
  • Improved ability to catch, troubleshoot maintenance issues


  • Health monitoring – from accelerometers, tachometers. System shall be capable of recording raw and intermediate sensor data (such as synchronous time average) as well as condition indicators
  • Rotor track and balance (RTB) data gathering including providing conditioned 24V power to GE Enhanced Universal Tracking Device (EUTD) optical blade tracker and receiving/processing track data from the same
  • Aircraft state data – able to gather aircraft state parameter data from either ARINC-429 data bus (407GX configuration) or from dedicated sensors (407 analog configuration)
  • Data download – system shall be provide Wi-Fi, terrestrial cellular, and wired (Ethernet) download capabilities. 
    Note– it is acceptable to deliver a system without cellular data transfer capabilities for initial STC if the cellular data transfer capability is certified within 3 months of initial STC.
  • Ground station software – the system shall provide the ability to locally (“at aircraft”) receive, view HUMS data without an internet connection on a Microsoft Windows based device. Ground station software shall be capable of transmitting data to GPMS web server while connected to the internet
  • Web server – the web server shall display aircraft health, RTB and flight state data with access control to limit data viewing to individual operators (i.e., an operator will not have access to another operator’s data). Bell to have access to all aircraft data on web server
