Boeing Studied 777 Engine Upgrade Before Denver Incident: Report

Boeing reported on Thursday that he had been working to strengthen the 777’s engine cover for about two years before the horrors of United Airlines’ flights last weekend.

The Wall Street Journal reported that Boeing was working with the Federal Aviation Administration to strengthen the protective engine cover following similar problems on previous flights prior to Saturday’s emergency landing.

The report was during an investigation by United Airlines’ National Transportation Safety Board on Saturday and returned to Denver shortly after disembarking after the engine ignited and began to break.

No one was injured in the incident, but the episode cast doubt on jet maintenance.

On Tuesday night, the FAA ordered inspection of all Pratt & Whitney engines as well as broken ones.

Investigators attribute Denver’s case to a fan blade that broke shortly after takeoff due to metal fatigue and apparently broke an engine cover known as a cowling.

Both Boeing and the FAA avoided discussing details of their efforts to change the 777. Such changes usually require significant evaluation and testing.

“We are in constant contact with our customers and the FAA and are committed to ongoing efforts to introduce improved safety and performance throughout the fleet,” said a Boeing spokeswoman. ..

“We will continue to follow FAA guidance and keep you up to date on this issue and all issues related to safety and compliance.”

The FAA said it focused on the latest order of fan blade inspection of Pratt & Whitney engines and previous directives after the 2018 incident at 777.

“Redesigning the airframe and engine components is a complex process. One of our top priorities so far has been to reduce the risk of fan blade failure that could lead to cowling damage,” FAA spokesman said. Mann says.

“FAA is working with manufacturers to continually enhance safety. Proposed design changes for critical structures provide equal or improved levels of safety and unintended risks. Must be carefully evaluated and tested to ensure that it does not result in. “
