PT6B/-C7-T

Maintenance, Repair & Overhaul

PT6B/-C/-T (MRO)

The PT6 turboshaft engines – the PT6B, -C, and -T – are designed to power single- and twin-engine helicopters. The engines in the 1,000- to 2,000-shaft horsepower class are very popular, thanks to their reliability and durability. The new PT6C-series engines, such as the PT6C-67, come with Full-Authority Digital Engine Control (FADEC). The PT6C-67 has been selected to power the AW609 TiltRotor.

Maintenance for the PT6B/-C/-T is provided by P&CW's customer support network.
