LEAP-1B turbine durability kit certified by FAA and EASA; GEnx passes 50M flight hours

GE Aerospace said the FAA and EASA certified the LEAP-1B high-pressure turbine durability kit, which the company expects to double time on wing in hot and harsh operating environments. The release also reported an initial engine-level certification for the LEAP-1B reverse bleed system. Separately, it said the GEnx-1B fleet passed 50 million flight hours, and it described a hybrid-electric flight above 30,000 feet with NASA, BETA Technologies and Boeing.

• FAA and EASA certified the LEAP-1B high-pressure turbine durability kit; expected to double time on wing in harsh environments.
• Initial engine-level certification of the LEAP-1B reverse bleed system, which should reduce on-wing fuel nozzle replacements.
• GEnx-1B passed 50 million flight hours in just over 14 years; in service with more than 50 operators.
• Hybrid-electric propulsion flew above 30,000 feet with NASA, BETA Technologies and Boeing.
