KUSA - For the second time in a week, a United Airlines Dreamliner flight was diverted due to a mechanical issue.

Sunday morning a flight from Houston to Denver was turned around after brake indicator issue. Flight 94 took off from Houston but went back to the city after the issue was discovered. The aircraft landed safely just before 11 a.m. mountain time.

United says maintenance crews are conducting a review of the aircraft. All passengers were re-accommodated to their final destinations.

On Tuesday, another United Airlines Dreamliner flight made an unscheduled landing. That flight was on its way from Denver to Tokyo, when it was diverted to Seattle because of a problem with its oil filter.

The incidents come six months after the FAA and other officials grounded the Dreamliner worldwide due to troubles with its battery system.
