Airbus warned airlines of grounding some A320neo jets that are affected by Pratt & Whitney engine problems.
The European Aviation Safety Agency issued emergency restrictions on Friday which read “Several occurrences of engine in-flight shut-down (IFSD) and Rejected Take-Off (RTO) have been reported on certain Airbus A320neo family aeroplanes. While investigation is ongoing to determine the root cause, preliminary findings indicate that the affected engines, which have high pressure compressor aft hub modification embodied from ESN P770450, are more susceptible to IFSD.”
International Aero Engines model PW1127G-JM, or PW1127GA-JM, or PW1130G-JM, or PW1133G-JM, or PW1133GA-JM engines, having Engine Serial Number (ESN) P770450 or subsequent.
Airbus A320-271N, A321-271N and A321-272N aeroplanes, all manufacturer serial numbers (MSN).
(1) Within 3 flight cycles (FC) from the effective date of this AD, do not operate an aeroplane having two affected engines installed.
(2) Within 1 FC from the effective date of this AD, for an aeroplane having at least one affected engine(s) installed, ETOPS operations are not allowed.
(3) Inserting a copy of this AD in the ETOPS Configuration, Maintenance and Procedures (CMP) of concerned aeroplane models and, thereafter, operating that aeroplane on ETOPS accordingly, is acceptable to comply with paragraph (2) of this AD.
Airbus has been facing engine issues since A320neo entered service little more than 2 years ago. Pratt & Whitney had been replacing engines but the rate of components failure on engines are higher than expected. Lately the engine issues (Rolls-Royce and Pratt) are affecting airline operations and creating a financial headwind for Airlines.
