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.

New production 131-9A (Series 25 and above) and 131-9B (Series 49 and above) come from the factory with the diffuser installed and only need the encryption key to active the software. Earlier Series APUs already in service can be upgraded during the next major service event, without additional APU downtown.

The powerful combination of hardware and advanced software deliver HEM benefits that improve operational and bottom-line performance for operators. The redesigned diffuser is critical, but it’s the software that autonomously controls the diffuser to regulate airflow into the compressor section. As a result, the engine burns fuel more efficiently at lower temperatures, which reduces wear and tear on critical engine parts.
