The Dallas Airmotive and
Rolls-Royce Partnership

Dallas Airmotive and H+S Aviation have been servicing Rolls-Royce M250® engines since 1967. We offer a depth and breadth of experience on this workhorse engine that includes the earliest models through the more powerful variants of today.

Being a modular engine, we can support operators by offering module repair and overhaul, exchange and sales, component and accessory repair, as well as full engine sales, exchange, repair and overhaul. Aircraft can operate in almost any environment any time of the day, so our field service technicians are available to go on-site for your support. Whatever scenario fits your service needs, we can accommodate you.

We offer one of the most comprehensive M250 exchange and component inventories. We manage more than 1,000 line items for M250 and hold one of the largest inventories of M250 modules and engines available for exchange or outright sale. In addition, we maintain a complete stock of overhauled material ready for installation.

H+S Aviation also provides a high-quality training service for M250 series engine operators. The Rolls-Royce M250 training is both Rolls-Royce and EASA Part 147 approved and recognized for its in-depth execution by experienced instructors in Portsmouth, UK or at your local facility. H+S Aviation and Dallas Airmotive provide 24/7 technical support of the M250 engine series through our F1RST SUPPORT™ field service organisation and global support network.

Contact us whenever you need assistance with your M250 engine.
