Ohio doesn’t get many sandstorms. But an hour east of Cincinnati, on an otherwise sunny day, a dust devil is brewing. Atop a towering scaffold, a row of hoses pumps out dense clouds of powder and grit. They are instantly sucked, like a horizontal tornado, into the spinning fan blades of a jet engine a few feet away.
In the annals of engine production, the GE90 holds a special attraction for both the aviation world and the people at GE Aerospace who’ve worked on the engine program. Among commercial engines, the number of firsts it’s chalked up over the years is hard to beat: First to enter service with carbon-fiber composite fan blades. First certified at over 100,000 pounds of thrust. First engine certified for ETOPS (Extended-range Twin-engine Operational Performance Standards). First certified with an additive part. First program to employ analytics-based maintenance.
