Rollys-Royce said Tuesday it will start deliveries of Series 3.5 engine enhancement kits in December and install those kits onto C-130 planes of the service branch and the U.S. Air National Guard.
The Series 3.5 upgrade aims to prolong parts life and allow T56 engines to run at lower temperatures than previous versions.
The company has secured certification from the Federal Aviation Administration to integrate the Series 3.5 kits with commercial T56 engine versions.
Rolls-Royce also installed the Series 3.5 upgrade on the National Oceanic Atmospheric Administrationâs Hurricane Hunter WP-3DÂ aircraft.
