Increase Time-on-Wing and Lower Fuel Burn

Upgrade Your 131-9A APU with High-Efficiency Mode

This upgrade is intended for aircraft operating a 131-9A APU, including Airbus A319, A320, and A321 models. The high-efficiency mode upgrade for 131-9A auxiliary power units for single-aisle Airbus aircraft is expected to increase the average time-on-wing by 1,200 APU flight hours and reduce fuel burn by 2%.

Customers enrolled in Honeywell’s Maintenance Service Plan will have access to the upgrade for no additional cost. This upgrade can be installed during any regularly scheduled maintenance event for all aircraft and does not require additional downtime to implement.

“Now, more than ever, our airline customers are concerned with cost savings and operational efficiency. This upgrade is an easy, one-time modification enabled with software and will be available first for our Maintenance Service Plan customers, and later for all operators of 131-9A units,” - said David Shilliday, Vice President, Engines & Power Systems, Honeywell Aerospace.
