5 Reasons To Upgrade To 131-9A/9B HEM:
1-2% improvement in fuel efficiency, which can amount to as much as $9,000 per year, per aircraft depending on operating conditions.
Improved environmental performance, reducing carbon dioxide emissions by up to 22 metric tons per APU per year, depending on operating conditions.
On-wing time is improved up to 1,500 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 doesn't increase normal major service interval downtime. The upgrade can be made without removing the APU from the aircraft for APUs that were delivered with the new diffuser.
