Boeing 787 vs De Haviland Comet –Will History Repeat?

I know I’ve said it before,but this latest news from Jon Ostrower (aka FlightBlogger) about the recent Boeing 787 delay being due to a design flaw in the tail really makes me wonder if the 787 isn’t doomed to become the De Haviland Comet of our time.

According to Jon’s report,the problem was discovered in December and is related to the unpressurised tail section of the aircraft. Apparently:

Boeing made the announcement only a few days before people were expecting the first flight,catching many by surprise. With so much riding on this project and so many delays already experienced,Boeing were pushing hard to get the 787 in the air as soon as possible. That Boeing couldn’t start the test flights while addressing this problem in parallel showed us it was a big issue,something that would either lead to a structural failure in flight or would require so many changes that testing would have to start again after the modifications were made.

Subsequent to their announcement of a delay,it was confirmed that the issue involves wing flexing travelling into the fuselage leading to delamination of wing panels. This report and others do not paint a very pretty picture with many predicting that the 787 won’t fly until next year (2010).
