In California, the ruling in Beech Aircraft Corp. v. Rainey underscores the principle that expert testimony is critical when determining the aspects of negligence and causation in aviation cases.

Established the general acceptance standard for scientific evidence, emphasizing the requirement for reliable methods and principles in expert testimony.
Clarified that the trial court has the duty to ensure that expert testimony is not only relevant but also based on a reliable foundation.
