On 16 September, an American Airlines Boeing 767 (N349AN) operated domestic flight AA726 between Philadelphia and Los Angeles, United States. While cruising at 36,000 feet, the crew received a left engine (CF6) oil filter bypass message that required them to idle the engine. The crew then decided to divert to Columbus for a safe landing.
On 19 September, the aircraft was still idle at Columbus airport. American Airlines mechanics are currently replacing engine number one. Aviation enthusiast Jennifer (Twitter: @Jen_Niffer) is onsite and tweeted a few pictures and a video of the aircraft and the engine replacement.
