Egypt’s Nesma Airlines, which operates two leased Airbus A320-200s, has announced a change of lubricant manufacturer as it seeks to combat the hot desert conditions involved in flying in the Middle East.

Three years ago, Nesma started using Air BP Lubricants’s High Performance Capable Turbine Oil 2197. According to Air BP Lubricants, “The recommendation to switch oils came from the aircraft’s former operator, who had previously experienced the added benefits of using BPTO 2197 in other aircraft.”

AgustaWestland’s AW189 medium twin can run for 50 minutes after loss of gearbox lubrication, a condition that has caused several incidents among large transport category helicopters recently.

Loss of lubrication to the main gearbox (MGB) has been responsible for several crashes, ditchings and precautionary landings in large transport category helicopters in recent years. These accidents set off broad debate as to exactly what is required of main gearboxes under Part 29 certification of the U.S.

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.
