A manufacturing error is the latest issue for Boeing's 787 Dreamliners.

Flightglobal.com says delamination has been found on at least three 787s. Parts of the composite skin on the Dreamliners are delaminating, basically coming apart, near the back of the airplane.

All 50 Dreamliners that have been completed are reportedly undergoing inspections to see if they have similar issues. Boeing says it's on top of the issue.

All Nippon Airways says it hasn't experienced the problem in the five planes it has in service.

But ANA did have to cancel two of its first long-haul Boeing 787 flights on a new route between Tokyo and Frankfurt because of software glitches.

ANA spokeswoman Jean Saito says the Tokyo-based airline canceled a Jan. 26 flight out of Frankfurt due to a malfunction of the flaps system and a Jan. 30 flight out of Tokyo because of an error in the software that monitors aircraft controls.

ANA is the launch customer for Boeing's new twin-engine wide-body. Saito says the airline is working with Boeing to make it a better airplane.
