JetBlue flight JBU1416 departed Long Beach Airport, CA (LGB) runway 30 at 09:17, bound for Austin-Bergstrom International Airport, TX (AUS). The aircraft was on the initial climb when passengers heard a "bang". The number 2 engine reportedly had a malfunction. A smoke condition then developed in the cabin and oxygen masks were manually deployed. The flight then declared an emergency, and circled back to land on runway 30. After landing, the airplane was evacuated on the runway via the evacuation slides.
The probable cause of the engine failure and subsequent undercowl engine fire was due to the fatigue fracture of a high pressure turbine stage 2 disk blade retaining lug that released two blades which impacted the low pressure turbine case causing a fuel line to fracture spraying fuel on the hot engine cases where it ignited. During a machining operation of the disk lug, a tool mark was introduced that set up the area for fatigue cracks to initiate.
