Sikorsky is developing a next-generation main gearbox (MGB) with enhanced lubrication capabilities with built-in redundancy systems such as chip detectors and oil scavenge systems, according to Spencer Elani, Sikorsky’s S-92 program manager. “We are continuing to make a lot of improvements to the current gearbox, and to automate some of the features,” Elani said.

The new MGB is part of a program improvement plan to the oil supply system designed to prevent another catastrophic accident such the March 2009 crash of a Cougar Helicopter S-92 into the Atlantic Ocean. The aircraft crashed following oil loss due to failure of the MGB oil-filter bowl assembly.
