Naasco Northeast (Booth No. 1433) emphasized the availability of its Mercury Mod-Phase Two starter generator upgrade at Heli-Expo 2014 in Anaheim.
“A higher-flow fan brings the cooling air down about 70 degrees lower than the original Mercury Mod, introduced 19 years ago,” Naasco vice president Jim Leslie told AIN. Work began two years ago on Mercury Mod 2, with Naasco working with engineers at Sikorsky on the S-76.
“We guarantee 1,000-hour brush life, thanks to cooler operating temperatures, plus the engine cowlings stay cleaner due to reduced carbon dust,” Leslie added. “And, of course, the extra hours.”
Mercury Mod 2 is available for installation through FAA parts manufacturer approval (PMA). Leslie said Naasco has approximately 50 to 60 customers running the Mercury Mod 2 so far.
