A Southwest Airlines Boeing 737-700, registration N281WN, operating flight WN-3396 from Santa Ana to San Jose with 96 people on board, was climbing out of Santa Ana's runway 02L on November 6 when the crew stopped the climb at FL200 reporting right-hand engine (CFM56) problems and decided to divert to Los Angeles. The crew subsequently shut the engine down and continued for a safe landing on Los Angeles' runway 25L about 40 minutes after departure.

The airline reported the crew received an engine maintenance indication, and the FAA reported the crew reported engine issues. The Aviation Herald reported the aircraft was still on the ground in Los Angeles about 21 hours after landing.
