23/02/2021  Boeing engine blowouts investigated as older 777s are suspended

Business


​Showers of jet engine parts over residential areas on both sides of the Atlantic have caught regulators’ attention and prompted the suspension of some older Boeing Co planes from service.

Saturday’s incidents involving a United Airlines 777 in Denver and a Longtail Aviation 747 freighter in the Netherlands put engine maker Pratt & Whitney in the spotlight, though there is no evidence they are related.

Pratt & Whitney, which is owned by Raytheon Technologies Corp, said it was coordinating with regulators to review inspection protocols. It is expected to increase inspections ordered after previous incidents.

After the Colorado engine failure, when United Flight 328 dropped debris on a northern Denver suburb before landing safely, Boeing recommended the suspension of 777s with the same variant of PW4000 turbine. Japan, meanwhile, imposed a mandatory suspension.

The European Union Aviation Safety Agency (EASA) weighed in on Monday, requesting more information on the Pratt engines in light of both events. A woman sustained minor injuries in the Dutch incident, which scattered turbine blades on the town of Meerssen. One was found embedded in a car roof.
