Engine and parts shortages, amplified by an engine recall and Spirit Airlines’ collapse, have pushed owners to dismantle recently built Airbus A320neos rather than wait years for repairs or storage. Parts, especially engines and fan blades, fetch high prices and can make teardown more profitable than resale, driving a surge in young-aircraft retirements and boosting the secondhand parts market. Some stored Spirit aircraft may be parted out, sold to other carriers, or kept in desert storage, but many are being stripped and crushed to recover valuable components. » More on cnbc.com
