Duncan Aviation is spooling up on a program to support legacy Honeywell thrust reverser actuator system (TRAS) parts on GE CF6 and CF34 engines under a licensing agreement with Ontic. That agreement, awarded in September, calls for Duncan to service, support, exchange, and sell certain of the TRAS products. Ontic acquired the product line from Honeywell in 2023.

That agreement helps Duncan expand its support for legacy aircraft. The TRAS part numbers under the agreement are on more than 3,000 aircraft. Meanwhile, it further helps Ontic expand in the business jet arena.

“Duncan Aviation is a specialist in the business jet MRO market, an area where Ontic is looking to grow,” said Adam Payne, Ontic’s senior sales manager for Staverton. “They will help offer repair options and solutions for Ontic’s TRAS product lines in North America, extending capabilities and coverage to their customer base from their Lincoln, Nebraska facility.”

Tim Fidler, Duncan Aviation Components business development manager, noted that the MRO has years of experience repairing these components. Applicable components can be purchased through Duncan Aviation’s parts portal.

These include for CF34 business jet and regional airline engines: P/N 3272570-X (thrust reverser ballscrew actuator),126758-X (pneumatic drive unit), and 121754-X (flex shaft assembly). For CF6 engines: P/Ns 3272602-X (ballscrew gearbox assembly), 3269264-X (subsystem actuator), 3269086-X (subsystem feedback actuator), 3202278-X (check valve), and 320522-X (directional pilot valve).
