AD: CFM International S.A. Turbofan Engines

AD NUMBER: 2018-25-09

PRODUCT: All CFM International S.A. (CFM) LEAP-1B21, -1B23, -1B25, -1B27, -1B28, -1B28B1, -1B28B2, -1B28B2C, -1B28B3, - 1B28BBJ1, and -1B28BBJ2 turbofan engines.

ACTION: Final rule; request for comments.

SUMMARY:  This AD requires removing certain electronic engine control (EEC) system operation (OPS) and engine health monitoring (EHM) software and installing versions eligible for installation.

This AD was prompted by six aborted takeoffs on the similarly designed CFM LEAP-1A model turbofan engine after those engines did not advance to the desired takeoff fan speed due to icing in the pressure sensor line.

DATES: This AD is effective December 26, 2018. Comments must be received by January 25, 2019.

COST: The FAA estimates that this AD affects 100 engines installed on airplanes of U.S. registry. Operators may incur the following costs in order to comply with this AD:

  • Software removal and software installation - 1 work-hour × $85 per hour = $85 per aircraft.
