131-9A APU High Efficiency Mode – Upgrade Now

131-9A APU High Efficiency Mode – Upgrade Now

Honeywell has released a High Efficiency Mode (HEM) upgrade for its 131-9A auxiliary power unit for single-aisle Airbus aircraft. HEM meets our customers’ needs for more power on the aircraft, greater fuel-efficiency and a smaller environmental footprint.

 

4 Reasons to upgrade to 131-9A HEM:

 

  • 1-2% improvement in fuel efficiency, which can amount to as much as $11,000 per year, per aircraft depending on operating conditions.
  •  
  • On-wing time is improved an average of 1,200 hours, up to 1,800 hours dependent on operator use. That can mean 1-2 fewer shop visits over the life of the unit, with estimated savings of $315,000 per shop visit.
  •  
  • Reduced overall maintenance costs and lower spares requirements, thanks to longer time-on-wing. Larger operators may save up to 15% on spares.
  •  
  • Easy installation. The new diffuser is a form-fit replacement, so the upgrade does not increase normal major service interval downtime. For Series 25 and newer units, the upgrade can be made without removing the APU from the aircraft.

 

This upgrade is an easy, one-time modification enabled with software and will be available first for our Maintenance Service Plan customers, and soon for all operators of 131-9A units.
