What to do
Operators of affected Airbus A321-251NX aircraft with LEAP-1A32 engines must replace each affected fuel nozzle within 600 flight cycles or 10 flight cycles after the AD effective date on one engine, and within 800 flight cycles or 10 flight cycles on the other engine, then continue replacements every 600 flight cycles. Replacements can be performed on-wing or in-shop following specified maintenance manual tasks. Compliance with these intervals is mandatory starting from 20 September 2024.
Summary
EASA Airworthiness Directive 2024-0175 is a corrective directive addressing the replacement of fuel injection nozzles on CFM International LEAP-1A32 engines installed on specific Airbus A321-251NX aircraft. The directive targets fuel nozzles with part numbers 2085M31G02, 2085M31G03, and 2085M31G05 due to accelerated coking issues. This AD mandates timely replacement to maintain engine performance and safety.
What changed
EASA Airworthiness Directive 2024-0175 republished to correct a typographical error in the reference publication section. It introduces mandatory replacement intervals for affected fuel nozzles on LEAP-1A32 engines installed on certain Airbus A321-251NX aircraft. The directive establishes specific flight cycle thresholds for on-wing and in-shop replacements.
Why it matters
This directive is critical for aviation professionals as it addresses a potential loss of thrust control caused by coking in fuel nozzles, which could compromise flight safety. Operators and maintenance organizations must comply to prevent engine performance degradation and ensure continued airworthiness. The AD also provides clear maintenance intervals to support planning and compliance tracking.
