LITTLEFIELD, Ariz. • A federal investigator says the pilot of a small plane that crashed in far northwestern Arizona was flying well below what’s allowed by regulation. Newly licensed pilot, 19-year-old Daulton Whatcott, and his brother, 16-year-old Jaxon Whatcott — from Clinton, Utah — were headed to a basketball tournament in Nevada when the single-engine Cessna crashed near the Arizona-Utah border on July 20.
