GE has extended the time between overhaul (TBO) for new production and in-service H Series turboprop engnes to 4000 hours (from 3600 hours) for Agriculture, Utility and Business Aviation Aircraft. As part of the TBO hourly extension, GE will also eliminate the engine TBO cyclic limit for all H Series engines.

GE also announced improved warranty coverage of its H Series Fuel control unit (FCU) to 2500 hours from 1000 hours.

These TBO extensions were made possible by component testing and in-service experience, including data collected by the MVP-50 engine monitor unit installed in the 510G. 

This announcement took place at the 49th Annual NAAA conference held in Savannah Georgia December 6-10th.
