Over 3 Decades of Experience


Hancock Enterprises Inc. was the brainchild of Robert Hancock, who started the business in Nashville, Tennessee in 1982. Hancock Enterprises Inc. began as a mobile maintenance service, specializing in Garrett TPE 331 engine maintenance, Turbo Commanders and Lear Jets. Based out of Nashville Tennessee, the company spent a large majority of their early years working out of Fort Lauderdale, Florida.


Hancock Enterprises Inc. moved to a base of operations at the Smyrna Airport, MQY, in Smyrna, Tennessee. There they built their first engine shop and began doing heavy engine maintenance on all Garrett TPE 331 engines through -10. Hancock Enterprises also expanded their airframe maintenance as well as their interior and paint shop.


Hancock Enterprises Inc. moved from the Smyrna Airport to their current facility in Hermitage, Tennessee. The Hermitage, Tennessee facility is a full Honeywell TPE 331 overhaul and repair facility. It is equipped with a full engine test cell for all Honeywell TPE 331 engines from Pre-Century all the way to -11. It is an FAA Certified Repair Station Number OCKR173L, and also has an accessory shop to test and overhaul compensators, engine PPC’s, and Fuel Nozzles.


The airframe shop moved from Smyrna to Lafayette, Tennessee, 3M7, for the first year and then moved to Lebanon, Tennessee, M54. There we specialized in Turbo Commanders and did anything from 150hr inspections to major overhauls and engine conversions.


Our mobile maintenance expanded from minor to major airframe repairs. The airframe shop moved to its previous location in Dickson, Tennessee, M02, where we continued to specialize in Honeywell TPE 331 and Pratt and Whitney PT6 aircraft airframe maintenance.


The airframe shop moved from Dickson, Tennessee to Smyrna, Tennessee, MQY. Where we have expanded our capabilities once again by adding MT Propeller Sales and Field Service to our service network. We are continuing to expand and grow at our new facility in Smyrna, Tennesse to help support you and your aircraft with the best possible service and repairs.
