Factual narrative

THE PILOT RECEIVED A TELEPHONIC IFR CLEARANCE FROM CHINO TOWER. THE PILOT DEPARTED CORONA AND CONTACTED THE ONTARIO TRACON DEPARTURE CONTROLLER. THE CONTROLLER INSTRUCTED THE PILOT TO RESET HIS TRANSPONDER AND THE PILOT COMPLIED, BUT FAILED TO ACKNOWLEDGE ANY FURTHER TRANSMISSIONS. THE AIRPLANE CRASHED ABOUT ONE MINUTE LATER. THE RECORDED RADAR DATA REVEALED THE AIRPLANE WAS IN A CLIMBING RIGHT TURN, REACHING A MAXIMUM ALTITUDE OF 1,500 FT MSL (1,000 FT AGL) WHEN THE PLT INITIALLY CALLED ONTARIO TRACON. AFTER REACHING 1,500 FT THE AIRPLANE'S RATE OF TURN INCREASED AND IT BEGAN DESCENDING RAPIDLY. THE AIRCRAFT IMPACTED THE TERRAIN IN A 10 DEGREE NOSE LOW, 30 DEGREE RIGHT BANK ATTITUDE. THE INVESTIGATION DID NOT DISCLOSE ANY PREIMPACT MALFUNCTIONS OR FAILURES. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
