Recent engine failures in the Pratt & Whitney engines used in the Airbus A320 family has resulted in the grounding and inspection of 1,200 engines. Hungarian low-cost airline Wizz Air is among the airlines affected by this issue.
Technical Issues with Pratt & Whitney Engines
There have been issues with the Pratt & Whitney engines, specifically with microscopic contaminants found in the metal powder used in the turbine blades of the high-pressure stages. Engines produced between 2015 and 2021 are affected, requiring inspection and potentially replacement of the component.
Impact on Wizz Air
Wizz Air, along with other operators, is facing substantial engine inspections and repairs. Approximately 200 engines are due for overhaul by mid-September and an additional 1,000 engines within the next 9-12 months. This represents around 40% of the PW1100G-JM engines currently in service.
Safety Concerns and Repair Timelines
While there is no immediate safety concern, the inspection and repair of an engine can take up to 60 days. Pratt & Whitney is making efforts to minimize downtime for operators. However, previous engine failures have resulted in grounded aircraft due to lack of replacement engines, parts supply issues, and limited service capacity.
Impact on Share Prices
Pratt & Whitney has clarified that the engines currently in production are not affected by the issue. Airbus has stated that no delays in aircraft deliveries are expected. However, the news of the engine failures led to falling shares for companies such as Spirit, Jetblue, and Wizz Air.
Questions & Answers
What is the issue with Pratt & Whitney engines affecting travel in Budapest? A component used in the manufacture of a new generation Pratt & Whitney engine does not comply with the specifications. This means that 1,200 engines from the Airbus A320 family have to be taken out of service and inspected. The Hungarian low-cost airline Wizz Air is also affected.
What has been found in the Pratt & Whitney engines? Microscopic contaminants have been found in the metal powder used in the turbine blades of the high-pressure stages of engines produced between 2015 and 2021.
What will happen to the affected engines? The affected units must be inspected and, if necessary, the component will be replaced. The engines will then be reassembled and returned to the operator.
