Circumstances:
The captain and first officer were assigned a two-leg overnight on-demand cargo flight. The flight crew were accustomed to flying night cargo flights, had regularly flown together, and were experienced pilots. The first leg of the trip was uneventful and was flown by the captain; however, their trip was delayed 2 hours and 20 minutes at the intermediate stop due to a delay in the freight arriving. The flight subsequently departed with the first officer as the pilot flying. While enroute, about forty minutes from the destination, the flight crew asked the air traffic controller about the NOTAMs for the instrument landing system (ILS) instrument approach procedure at the destination. The controller informed the flight crew of two NOTAMs: the first pertained to the ILS glidepath being unserviceable and the second applied to the localizer being unserviceable. When the controller read the first NOTAM, he stated he did not know what “GP” meant, which was the abbreviation for the glideslope/glidepath on the approach. The controller also informed the flight crew that the localizer NOTAM was not in effect until later in the morning after their expected arrival, which was consistent with the published NOTAM. The flight crew subsequently requested the ILS approach and when the flight was about 15 miles from the final approach fix, the controller cleared the flight for the ILS or localizer approach, to which the captain read back that they were cleared for the ILS approach. As the flight neared the final approach fix, the captain reported that they had the airport in sight; he cancelled the instrument flight rules flight plan, and the flight continued flying towards the runway. The airplane crossed the final approach fix off course, high, and fast. The cockpit voice recorder (CVR) transcript revealed that the captain repeatedly instructed the first officer to correct for the approach path deviations. Furthermore, the majority of the approach was conducted with a flight-idle power setting and no standard altitude callouts were made during the final approach. Instead of performing a go-around and acknowledging the unstable approach conditions, the captain instructed the first officer to use the air brakes on final approach to reduce the altitude and airspeed. Shortly after this comment was made, the captain announced that they were low on the approach and a few seconds later the captain announced that trees were observed in their flight path. The CVR captured sounds consistent with power increasing; however, the audible stall warning tone was also heard. Subsequently, the airplane continued its descent and impacted terrain about .70 nautical mile from the runway. The airplane was destroyed by impact forces and both occupants were killed.
Probable cause:
The flight crew’s continuation of an unstable dark night visual approach and the captain’s instruction to use air brakes during the approach contrary to airplane operating limitations, which resulted in a descent below the glide path, and a collision with terrain. Contributing to the accident was the captain’s poor crew resource management and failure to take over pilot flying responsibilities after the first officer repeatedly demonstrated deficiencies in flying the airplane, and the operator’s lack of safety management system and flight data monitoring program to proactively identify procedural non-compliance and unstable approaches.

Circumstances:
Aircraft was destroyed following a collision with a utility pole, trees, and terrain following a go-around at Thomson-McDuffie Regional Airport (HQU), Thomson, Georgia. The airline transport-rated pilot and copilot were seriously injured, and five passengers were fatally injured. The airplane was registered to the Pavilion Group LLC and was operated by the pilot under the provisions of 14 Code of Federal Regulations Part 91 as a business flight. Night visual meteorological conditions prevailed, and an instrument flight rules flight plan was filed. The flight originated at John C. Tune Airport (JWN), Nashville, Tennessee, about 1828 central standard time (1928 eastern standard time). The purpose of the flight was to transport staff members of a vascular surgery practice from Nashville to Thomson, where the airplane was based. According to initial air traffic control information, the pilot checked in with Augusta approach control and reported HQU in sight. About 2003, the pilot cancelled visual flight rules flight-following services and continued toward HQU. The last recorded radar return was observed about 2005, when the airplane was at an indicated altitude of 700 feet above mean sea level and 1/2 mile from the airport. There were no distress calls received from the crew prior to the accident. Witnesses reported that the airplane appeared to be in position to land when the pilot discontinued the approach and commenced a go-around. The witnesses observed the airplane continue down the runway at a low altitude. The airplane struck a poured-concrete utility pole and braided wires about 59 feet above ground level. The pole was located about 1/4 mile east the departure end of runway 10. The utility pole was not lighted. During the initial impact with the utility pole, the outboard section of the left wing was severed. The airplane continued another 1/4 mile east before colliding with trees and terrain. A postcrash fire ensued and consumed a majority of the airframe. The engines separated from the fuselage during the impact sequence. On-scene examination of the wreckage revealed that all primary airframe structural components were accounted for at the accident site. The landing gear were found in the down (extended) position, and the flap handle was found in the 10-degree (go-around) position. An initial inspection of the airport revealed that the pilot-controlled runway lights were operational. An examination of conditions recorded on an airport security camera showed that the runway lights were on the low intensity setting at the time of the accident. The airport did not have a control tower. An inspection of the runway surface did not reveal any unusual tire marks or debris. Weather conditions at HQU near the time of the accident included calm wind and clear skies.
Probable cause:
The pilot's failure to follow airplane flight manual procedures for an antiskid failure in flight and his failure to immediately retract the lift dump after he elected to attempt a go-around on the runway. Contributing to the accident were the pilot's lack of systems knowledge and his fatigue due to acute sleep loss and his ineffective use of time between flights to obtain sleep.

Circumstances:
The twin-engine turboprop aircraft had just completed a medical evacuation (MEDEVAC) flight from Coral Harbour, Northwest Territories (NWT), to Churchill, Manitoba. At 2257 central daylight saving time (CDT), the aircraft departed Churchill for a night, instrument flight rules (IFR) flight to return to the aircraft's base of operations at Thompson, Manitoba. The en route portion of the return leg was conducted at an altitude of 18,000 feet above sea level (asl). Approximately one hour after take-off, the aircraft commenced an approach to the Thompson Airport. The crew remained in radio contact with air traffic control (ATC) personnel until approximately 2359 CDT. Just after midnight (0001 CDT), the Hotel non-directional beacon (NDB), which is located 3.4 miles northeast of the Thompson Airport, stopped transmitting. Ninety minutes later, the search and rescue satellite system (SARSAT) picked up an emergency locator transmitter (ELT) signal to the northeast of the airport. Thompson Airport staff, who had been dispatched to the site of the failed navigation beacon, found the wreckage of the aircraft in and around the NDB transmitter compound. Emergency responses were initiated by various airport and local authorities.
Probable cause:
The flight crew lost altitude awareness during the localizer back course approach and allowed the aircraft to descend below a mandatory level-off altitude. Contributing factors to this occurrence were the crew's deviation from a published approach procedure, ineffective in-flight monitoring of the approach, rapidly developing localized fog conditions, and, probably, pilot fatigue.

Circumstances:
While cruising at an altitude of 21,000 feet, the pilot was cleared to climb to 23,000 feet when the airplane's speed dropped about 53 knots. The airplane entered a rapid descent and was observed spinning until it crashed in a field. All five occupants were killed.
Probable cause:
Stall and rapid descent due to improper in-flight decisions. The following contributing factors were reported:
- Airframe ice,
- The pilot failed to maintain flying speed,
- Incorrect weather briefing,
- Icing conditions including sleet, freezing rain.
