Summary
The FAA is adopting a new airworthiness directive (AD) for certain CFM International S.A. (CFM) LEAP-1B21, -1B23, -1B25, -1B27, - 1B28, -1B28B1, -1B28B2, -1B28B3, -1B28B2C, -1B28BBJ1, and -1B28BBJ2 model turbofan engines. This AD requires initial and repetitive inspections of the transfer gearbox (TGB) scavenge screens and, depending on the results of the inspection, possible removal of the engine from service. This AD was prompted by multiple reports of in- flight shutdowns (IFSDs) due to radial drive shaft (RDS) bearing failure. The FAA is issuing this AD to address the unsafe condition on these products.
