WALTHAM, MASSACHUSETTSLast week, Pratt & Whitney's parent company Raytheon Technologies said the engine manufacturer might not deliver around 70 engines to Airbus for the first quarter of 2022 due to casting shortages.

"Pratt will probably not ship... let's call it 70 engines to Airbus, because of the casting shortages that we're seeing," Raytheon Chief Executive Greg Hayes said at the Barclays Industrial Conference.

This confirms the pressure on the planemaker's suppliers as Airbus increases its production rates. Some planes on the manufacturer's backlog have already been a few months late and could slip to 2023 if those engines are not delivered as previously planned.
