Sikorsky devotee VIH debuts S-92A kit upgrade
In the event of a loss of primary lubrication system oil pressure, a new gearbox has demonstrated the ability to provide return to base capability for a range of more than 400 nautical miles.
The upgrade provides gearbox peace of mind

Canada's Cougar Helicopters, the operating company of VIH Aviation Group, has become the launch customer for Sikorsky's S-92A+ upgrade. The operator has been an S-92 customer since 2004.

The S-92A+ upgrade kits feature the Phase IV main gearbox, validated to exceed CFR 29.927(c) requirements as demonstrated in full-scale testing. In the event of a loss of primary lubrication system oil pressure, the gearbox has demonstrated the ability to provide return to base capability for a range of more than 400 nautical miles.

The S-92A+ upgrade kit also includes an increase to 27,700 lb. maximum gross weight with LifePlus improving component retirement times.

“The S-92A+ and S-92B programmes demonstrate Lockheed Martin's commitment to the commercial business and to our customers,” says Sikorsky Commercial Systems and Services vice president Audrey Brady. “This programme will enhance safety and lower operating costs, and we are honoured to work with VIH as our launch customer for this programme."

“VIH Aviation Group Ltd. is pleased to be the lead customer for the Sikorsky S-92A+ kit,” adds Ken Norie, president and owner of VIH Aviation Group Ltd. “This kit will improve our S-92 fleet's performance and capacity and enables VIHAG companies to continue providing our customers industry-leading, all-weather and deep-water offshore SAR, medevac and passenger transportation.”

The S-92A+ upgrade kit and new production S-92B aircraft will share new technologies while providing enhanced reliability and improving economics to fleet operators. Sikorsky anticipates the S-92A+ kit will be delivered by 2023 and the S-92B helicopter in 2025.
