PROVEN ENGINEERING AND OPERATING HISTORY

Since October of 1997, the Garlick Helicopter Corporation, FAA approved Tail Boom Fin Spar Modification has been installed in nearly 60 aircraft with accumulated operating times of over 12,000 hours. The majority of these aircraft are performing Repeated Heavy Lift Operations, with no reported problems. GHC was the first to engineer a totally re-designed assembly and does not use previously problematic aluminum caps with unproven cold-worked rivet holes. It provides infinite “Fatigue Cycle Life”
