After software problems of B737 MAX types, Boeing is now struggling for the same type’s quality control problems. The problem came to the surface when the door plug blew off because it left the factory missing crucial bolts needed to keep it in place. Many airlines grounded Boeing’s brand new narrow-body type after the incident.
While Boeing is grappling with quality problems, things are not going well for Airbus, either. According to aviation sources, Airbus’ A320 and A321 planes have serious problems with their engines. As per open source information, many Airbus planes powered with PW1100G-JM (GTF) engines, which are produced by Pratt&Whitney, have been grounded by airlines for repair and check.
One of the major problems with the PW1100G engine was related to the knife-edge seal in the High-Pressure Compressor (HPC) aft hub. This component experienced premature wear, resulting in unexpected engine shutdowns and airline operational disruptions. The second problem is concerns the contaminated metal in some of the engine’s parts, which could potentially lead to cracking.
It is claimed that at least 3000 engines have the said problem. While carriers and the producer company are aware of the problem and trying to take precautions, to what extent airlines consider the risk is a matter of question.
