Models named: LEAP-1A32, A321-251NX. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to CFM International, S.A. (CFM) Model LEAP-1A32 engines installed on Airbus SAS Model A321-251NX airplanes having any of the following airplane serial numbers: 11200, 11420, 11473, 11609, 11698, 11791, 11815, 12136, 12314, and 12370.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

(1) At the applicable times specified in paragraphs (g)(1)(i) and (ii) of this AD, replace the full set of fuel nozzles, on each engine, with parts eligible for installation. (i) On either affected engine installed on the airplane: Before accumulating 600 flight cycles (FCs) since new or since last replacement of the full set of fuel nozzles, or within 10 FCs after the effective date of this AD, whichever occurs later. (ii) On the other affected engine installed on the same airplane: Before accumulating 800 FCs since new or since last replacement of the full set of fuel nozzles, or within 10 FCs after the effective date of this AD, whichever occurs later. (2) Thereafter, on each affected engine installed on the airplane, at intervals not to exceed 600 FCs since last replacement of the full set of fuel nozzles, replace the full set of fuel nozzles with parts eligible for installation.

Unsafe condition

This AD was prompted by a report of multiple events of loss of thrust control during go-around. The FAA is issuing this AD to prevent the loss of engine thrust control. The unsafe condition, if not addressed, could result in reduced control of the airplane.

Affected ADs

None.
