ABOUT US


HAMMOCK AVIATION SERVICES, INC. WAS STARTED AS GARY HAMMOCK AVIATION SERVICES IN 1994. AFTER 35 + YEARS OF DESIGNING AND FABRICATING STAINLESS STEEL RESTAURANT AND FOOD PLANT EQUIPMENT, GARY WAS READY FOR A CHANGE, HE HAD ALWAYS ENJOYED WORKING ON HIS OWN BONANZA, SO HE DECIDED TO TRY HIS HAND AT THE BONANZA MOD/REPAIR BUSINESS AS A JOB/HOBBY. SOON THE DEMAND FOR HIS SERVICES WAS SUCH THE HE OUTGREW HIS SINGLE “T” HANGAR, RENTED ANOTHER NEXT DOOR AND THEN MOVED INTO A 10,000 SQ. FT. FACILITY AT ENNIS MUNICIPAL AIRPORT (F-41) ENNIS, TX., JUST SOUTH OF DALLAS, TX.

JERRY HAMMOCK JOINED THE COMPANY IN 1998 AND HAMMOCK AVIATION SERVICES, INC. WAS FORMED. THEY ARE ALSO THE FBO OPERATOR AT F-41 PROVIDING HANGAR SPACE, FUEL SERVICE FOR GENERAL AVIATION.

BOTH GARY AND JERRY OWN BONANZAS, FLY THEM ON A REGULAR BASIS, AND OF COURSE MAINTAIN AND MODIFY THESE FINE AIRCRAFT.

GARY’S FIRST BONANZA WAS A 1949 MODEL, A35 AND HE SAW THE NEED FOR SOME UPDATES AND MODIFICATIONS TO THESE SERIES AIRCRAFT. THE FIRST MOD WAS THE PIANO KEYS & UP INSTRUMENT PANEL, THEN THE FIREWALL FORWARD BATTERY BOX. SHORTLY AFTER THAT HE WENT BACK TO THE DRAWING BOARD AND WORKED UP THE LATE STYLE SEAT CONVERSION.

GARY IS THE CO-FOUNDER OF THE “CLASSIC BONANZA ASSOCIATION” AND AFTER TWO DIFFERENT MISHAPS WHERE ASSOCIATION MEMBERS AND GOOD FRIENDS CRASHED THEIR BONANZAS, HE SAW THE NEED FOR A GOOD SHOULDER HARNESS SYSTEM. SO BACK TO THE DRAWING BOARD WHERE THE SYSTEM WAS DESIGNED, INSTALLED IN A J-35 FUSELAGE (FROM ONE OF THE CRASHES) AND OFF TO THE TESTING LAB WITH THE FAA IN ATTENDANCE AND THEIR APPROVAL.

GARY AND JERRY ARE HOTRODDERS AT HEART AND HAVE DESIGNED AND BUILT THEIR OWN RACE CARS, DIRT TRACK SPRINT CARS, MIDGETS, MODIFIEDS ETC. JERRY IS A VERY ACCOMPLISHED DRIVER WINNING CONSISTENTLY AT AREA TRACKS, WHICH HE STILL CONTINUES TO DO. SO CAME THE DESIRE TO UPGRADE THE OLD 1949 MODEL A35 BONANZA WITH A BIGGER ENGINE, “BIGGER IS BETTER” THE INSTALLATION OF THE 260 HP, IO-470-N ENGINE IN THIS AIRCRAFT WAS ONE OF THE MOST GRATIFYING MODS WE HAVE DONE. "PERFORMANCE IS FANTASTIC".
