What to do
Operators of Group 1 LEAP-1A engines must update the FADEC software within three months from 22 October 2018, following the instructions in the specified CFM Service Bulletin. Installation of any electronic engine control units with affected software is prohibited after modification or from the effective date for Group 2 engines. Compliance with these requirements is mandatory to continue operation.
Summary
EASA Airworthiness Directive 2018-0216 is an airworthiness directive addressing the CFM International LEAP-1A series engines installed on various Airbus A320neo family aircraft. It mandates the replacement of Full Authority Digital Electronic Control (FADEC) software to prevent engine thrust issues during take-off. The directive applies to multiple LEAP-1A engine models and aims to enhance engine control system reliability.
What changed
This directive introduces a mandatory update to the FADEC software on affected LEAP-1A engines to a newer version that improves fault detection related to pressure sensor discrepancies. It prohibits installation or uploading of older, affected software versions on any engine and requires operators to update existing software within a specified timeframe.
Why it matters
This update is critical for aviation professionals because the affected software versions can cause thrust loss during take-off, posing a safety risk. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and avoid operational disruptions. The directive also clarifies acceptable software versions and installation restrictions to prevent recurrence of the issue.
