US passenger Jennifer Riordan was travelling on a flight from New York to Dallas when a fan blade disintegrated at 32,000 feet, showering the fuselage with debris and shattering the window near her.

The type of CFM engine affected is the same type used by Tui Airways and Jet2.com on some of their Boeing 737s, and is found on some Ryanair aircraft.

In the days after the tragedy, US and European Union safety regulators issued Airworthiness Directives calling for immediate inspections of the affected engine types.

A Tui spokesperson added: “We carry out routine maintenance on all of our aircraft, including the 33 Boeing 737-800 aircraft we have in our Tui Airways fleet.”

A Jet2.com spokesperson said: “The safety of our customers is always our number one priority, and we are performing appropriate inspections in line with regulatory guidance.”

Ryanair said: “Less than 70 of our aircraft are fitted with these engines. All have been inspected in full compliance with the CFM and Easa service directives. If any further checks or actions are required then these will be promptly and fully complied with.”
