Incident: JAL B773 at Tokyo on Sep 5th 2017, engine shut down in flight following uncontained failure   A JAL Japan Airlines Boeing 777-300, registration JA743J performing flight JL-6 from Tokyo Haneda (Japan) to New York JFK,NY (USA) with 233 passengers and 15 crew, was in the initial climb out of Haneda's runway 34R when the left hand engine (GE90) emitted a series of 5 bangs and streaks of flame. Tower informed the crew about seeing flames out of the engine. The crew receiving abnormal indications for engine #1 stopped the climb at 6000 feet, shut the engine down, dumped fuel and returned to Haneda for a safe landing on runway 34L about one hour after departure. Metal debris was found on the departure runway. A replacement Boeing 777-300 registration JA741J is estimated to reach New York with a delay of 6.5 hours. The airline initially suspected a bird strike but later reported that no bird remains were found. The cause of the engine failure is under investigation. Japan's Ministry of Transport reported the grass left of the departure runway caught fire when the engine distributed debris onto the runway. An inspection of the engine did not reveal any bird remains. A number of blades of the low pressure turbine were missing. On Sep 7th 2017 Japan's TSB rated the accident type as: "Things similar to 'breakage of the engine (only when the debris penetrates the case of the engine)'" effectively describing the engine failure was uncontained. The JTSB have opened an investigation.
