Airworthiness Directive · Amendment 39-22849 · Engine fuel and control
CFM International, S.A. Engines
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.
The FAA is adopting a new airworthiness directive (AD) for certain CFM International, S.A. (CFM) Model LEAP-1A32 engines. This AD was prompted by a report of multiple events of loss of thrust control during go-around. This AD requires replacement of the full set of fuel nozzles. The FAA is issuing this AD to address the unsafe condition on these products.
(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.
For the purpose of this AD, “parts eligible for installation” are new fuel nozzles or fuel nozzles made serviceable using CFM Component Maintenance Manual (CMM) 73-11-30 (CFM-TP.CM.056.), any revision.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
