Circumstances:
The twin engine aircraft entered the Dominican airspace without clearance while probably being involved in an illegal mission (contraband). After being traced by an A-29B Super Tucano, it crashed in unknown circumstances in a sugar cane field located in Batey Palo Bonito. The aircraft was destroyed by impact forces and a post crash fire and both occupants were killed.

Circumstances:
The private pilot, who was the owner of the airplane, and a flight instructor were performing a recurrent training flight. Radar data showed that the airplane departed and climbed to an altitude about 5,000 ft above ground level. About 5 minutes after takeoff, the airplane conducted a left 360° turn followed by a right 360° turn, then continued in level flight for about 2 minutes as it slowed to a groundspeed of about 90 knots, which may have been indicative of airwork leading to slow flight or stall maneuvers. The airplane then entered a steep bank and impacted the ground in a nose-low attitude. Both engines and propellers displayed evidence of operation at the time of impact, and postaccident examination revealed no mechanical anomalies that would have precluded normal operation of the airframe or engines. The instructor had a history of obstructive sleep apnea. The investigation was unable to determine how well the condition was controlled, if he had symptoms from the condition, or if it contributed to the accident. Toxicology testing revealed low levels of ethanol in specimens from both pilots; however, it is likely that some or all of the ethanol detected was a result of postmortem production, and it is unlikely that alcohol impairment contributed to the accident. Toxicology testing also detected the primary psychoactive compound of marijuana, tetrahydrocannabinol (THC), and its metabolite, tetrahydrocannabinol carboxylic acid (THCCOOH), in specimens obtained from comingled remains; the investigation was unable to reliably determine which pilot had used the impairing illicit drug. Additionally, it is not possible to determine impairment from tissue specimens; therefore, the investigation was unable to determine whether THC impaired either of the pilots or if it may have contributed to the accident.
Probable cause:
A loss of control while maneuvering for reasons that could not be determined because postaccident examination did not reveal any mechanical malfunctions or anomalies with the
airplane.

Circumstances:
The twin engine aircraft was flying to Zāhedān with a crew of three (two pilots and a flight attendant) and four passengers, among them General Mahmoud Sadeqi, a senior police officer in charge of investigations, who was travelling to Zāhedān to investigate an incident involving an attack on police. While approaching Zāhedān by night, the aircraft hit a mountain located in the Sabzpushan Heights, north of the airport. All seven occupants were killed. A day later, Iranian authorities said the accident was caused by technical flaws, darkness and the pilot’s unfamiliarity with the region.
