Voices of Satisfied Pilots and Operators

“I recently hired your company to perform an engine overhaul for my Cessna 150 engine, a Continental O-200-A. At this point in time the engine is running well, nice and smooth. During the process a few issues surfaced which required your company to resolve, which you promptly did. I was both pleased and impressed with your handling of the matter. Therefore, I wish to compliment your company, and thank you for excellent service, and customer support. I fly two other aircraft regularly, and if we ever needed in the future an overhaul your company would be my first choice. In addition, anytime a discussion of overhaul companies arises I will promote your company as an excellent choice.”

“Signature overhauled my engine. After it was out of warranty I noticed a hot cylinder. They still took my plane, checked out the engine and found it to be working fine. Despite this they continued to troubleshoot the hot cylinder and resolve the problem. John Buckles is a standup guy!”

“We had an engine that a previous shop started then closed its doors in the middle of my build leaving me with a box of unassembled parts that had been sitting stagnant for almost 3 yrs, John and his shop took on the project to finish the build for me.
Communication was great pricing was excellent compared to other shops I had talked to and they had my engine back to me in under 6 months.
As the owner of a small mx shop it’s nice to find quality service with excellent communication these days I will definitely send any other engine here in the future.”

“I worked with John and his team to complete a major overhaul for my IO550N/Cirrus SR22.
The quality of workmanship, communication, and responsiveness was exemplary. They completed my project ahead of schedule and on-budget. I will be using them for my next project. Cannot recommend them enough.”
