On 9 December 2012, a Learjet 25 business jet carrying five passengers including American singer Jenni Rivera crashed south of Monterrey, Mexico, minutes after taking off from the city's international airport.

[1] The subsequent investigation was unable to determine the cause of the sudden steep descent that led to the aircraft impacting the ground at extremely high speed.

Around 15 minutes later, while still climbing towards its assigned cruise level, the aircraft suddenly went into a steep descent and disappeared from radar, crashing to the ground.

[7] From the analysis of the recorded radar information, it was determined that the Learjet had experienced a sudden loss of control while climbing through 28,000 feet (8,500 m), leading to a nearly vertical high-speed nosedive.

[7] Other flight crews that had previously flown on N345MC had reported occurrences of anomalous vibrations felt on the control column during cruise, leading the investigators to speculate that the sudden nosedive might have been the result of a failure in the horizontal stabilizer, although no hard evidence was found among the badly damaged parts of the system recovered from the wreckage.
