Some of our work
Keeping cool under pressure
YZF — Yellowknife, Canada
When a United Boeing 777-200 was forced to divert in Yellowknife, Canada due to a non-routine engine issue, temperatures below -47°F further complicated an already difficult situation. Our GEM team was dispatched to support the aircraft on ground, and with cold weather gear and all the necessary resources on hand, they collectively addressed the engine change on site, expediting the aircraft’s return to service within 24 hours.
Finding solutions abroad
DNA — Kadena Air Base, Okinawa, Japan
After a customer’s Boeing 777-200 PW4090 engine failed on climb out from Kadena Air Base in Okinawa, Japan, it was forced to return to the field, and our GEM team was quickly dispatched. With all the necessary equipment, tooling, personnel and a spare engine, the GEM team completed all the inspections and repairs. They replaced the failed engine with the serviceable spare engine and accelerated the aircraft’s return to service, allowing it to complete its flight to its destination in the U.S.
Putting out fires, big and small
LAX — Los Angeles, California
When a customer’s A320 family aircraft was damaged as a result of a ground equipment fire while under tow at LAX, United Technical Operations’ GEM team was notified. All appropriate engineering, inspections and repairs were completed to the skin and underlying structure, including NLG assembly, removal and replacement, hastening the aircraft’s return to service in approximately six days.
