An engine problem that has grounded the Boeing 737 Max test fleet has no effect on Airbus A320neo family aircraft powered a different version of the powerplant, CFM International confirms.
Though sharing a common overall architecture, the Leap-1A powering the A320neo family uses a different part design for the low pressure turbine disc than the Leap-1B engine powering the 737 Max, CFM says.
The LPT disc itself for the Leap-1A also is made by a different supplier than the same part for the Leap-1B, says the joint venture of GE Aviation and Snecma.
Boeing grounded the 737 Max test fleet to investigate a problem found by CFM during manufacturing quality inspections of the Leap-1B component.
CFM notified Boeing about the manufacturing quality issue last week.
Despite the LPT disc issue, Boeing expects to resolve the problem and deliver the first 737 Max 8 to launch operator Malindo, a subsidiary of Lion Air Group, later this month.
