This crash occurred on January 31, 2000, as the MD83 aircraft was flying from PVR to SFO. The final investigation revealed improper maintenance. A mechanic had reported issues, but then was fired. Alaska Airlines management was involved in a cover up of their shoddy maintenance procedures. They changed maintenance procedures and falsified maintenance work to save money. Below is a short re-creation of the final flight. The pilots were unable to pull the aircraft out of a dive. How no one at Alaska Airlines went to prison for this accident is beyond me.
