Japan Airlines to retire 777 planes with Pratt & Whitney engines after United incident
Japan Airlines Co Ltd (JAL) said it had retired its fleet of 13 Boeing Co 777s with Pratt & Whitney engines a year earlier than planned, having suspended operations in February after an engine on a United Airlines plane shed debris.

Sad end to a great Airplane, these will will make fine Sushi houses...
A sensible decision by JAL. This move will add pressure for United to retire their dozens of PW powered 777s, some of them the oldest ones produced. Line numbers 4 and 5 were the United ones that had blades failed & lost cowlings.
Wonder how difficult (if it makes sense of course...) to re-engine them with GE?
Over all too much money as the planes probably are worth much less than two new engines let alone what is required to change them over.
Sometimes the best of intensions fail, in hindsight the design of the 4077 blade set up the failure mode and the TAI inspection process was questionable at best. As an Engineer with over 50 years in and around the aviation world, I think all designs must ere on the side of conservative material properties and I have my doubts about the growing size of fan blades especially on two engine aircraft flying over long expanses of ocean
The verb is "err" not ere. Sorry to be such a grammar nazi. Good comment!
