Narrative:
Learjet 24B N600XJ departed Chino (CNO) at 08:58 and was cleared to climb to an altitude of 29,000 feet. About 09:09, after the airplane climbed through an altitude of 26,000 feet, the first officer requested a return to Chino. The controller asked if he needed to declare an emergency, and the first officer replied that he did not. The controller then directed the flight crew to maintain an altitude of 24,000 feet. As the flight was cleared directly to HECTOR, the airplane descended below the assigned altitude, at a rate of about 6,500 fpm. About 09:11:24, while the airplane was descending at a rate of about 10,000 fpm, the first officer stated, "we're declaring an emergency now." This was the last contact with the flight. The airplane impacted the top of a ridgeline in desert terrain at an elevation of 3,350 feet.
