Circumstances:
The aircraft collided with a ditch during a precautionary landing after takeoff from Savannah/Hilton Head International Airport (SAV), Savannah, Georgia. The pilot and copilot sustained minor injuries, and the airplane was substantially damaged. The airplane was registered to Upper Deck Holdings, Inc. and was being operated by PlaneSense, Inc,. as a Title 14 Code of Federal Regulations Part 91 positioning flight. Visual meteorological conditions prevailed, and an instrument flight rules flight plan was filed for the flight to Blue Grass Airport (LEX), Lexington, Kentucky. The pilot in the left seat was the pilot monitoring and the copilot in the right seat was the pilot flying. The crew had the full length of the runway 1 available (7,002 ft) for takeoff. The pilots reported that the acceleration and takeoff was normal and after establishing a positive rate of climb, the crew received an auditory annunciation and a red crew alerting system (CAS) torque warning. The engine torque indicated 5.3 pounds per square inch (psi); the nominal torque value for the conditions that day was reported by the crew to be 43.3 psi. With about 2,700 ft of runway remaining while at an altitude of 200 ft msl, the copilot elected to land immediately; the copilot pushed the nose down and executed a 90° left descending turn and subsequently landed in the grass. Although he applied "hard" braking in an attempt to stop, the airplane impacted a drainage ditch, resulting in substantial impact damage and a postimpact fire. The pilot reported that, after takeoff, he observed a low torque CAS message and the copilot told him to "declare an emergency and run the checklist." The pilot confirmed that the landing gear were extended and the copilot turned the airplane to the left toward open ground between the runways and the terminal. About 60 seconds elapsed from the start of the takeoff roll until the accident. The airport was equipped with security cameras that captured the airplane from its initial climb through the landing and collision. One camera, pointed toward the west-southwest, recorded the airplane's left descending turn and its landing in the grass, followed by impact and smoke. A second camera, mounted on the control tower, pointed toward the southeast and showed the airplane during the initial climb before it leveled off and entered a descending left turn; it also showed the airplane land and roll through the grass before colliding with the ditch.
Probable cause:
The pilots' failure to follow proper procedures in response to a crew alerting system warning for high engine torque values, which necessitated an off-runway emergency landing during which the airplane sustained substantial damage due to postimpact fire. Contributing to the accident was the erroneous engine torque indication for reasons that could not be determined.

Circumstances:
The aircraft crashed during takeoff from Blue Grass Airport, Lexington, Kentucky. The flight crew was instructed to take off from runway 22 but instead lined up the airplane on runway 26 and began the takeoff roll. The airplane ran off the end of the runway and impacted the airport perimeter fence, trees, and terrain. The captain, flight attendant, and 47 passengers were killed, and the first officer received serious injuries. The airplane was destroyed by impact forces and post crash fire. The flight was operating under the provisions of 14 Code of Federal Regulations Part 121 and was en route to Hartsfield-Jackson Atlanta International Airport, Atlanta, Georgia. Night visual meteorological conditions prevailed at the time of the accident.
Probable cause:
The flight crew members' failure to use available cues and aids to identify the airplane's location on the airport surface during taxi and their failure to cross-check and verify that the airplane was on the correct runway before takeoff. Contributing to the accident were the flight crew's non pertinent conversation during taxi, which resulted in a loss of positional awareness, and the Federal Aviation Administration's failure to require that all runway crossings be authorized only by specific air traffic control clearances.

Circumstances:
Shortly before landing, the crew confirmed that the hydraulic and emergency air pressures were "good", and that the circuit breakers on the "right and left" were in. In addition, the first officer reported "arming one and two." The airplane landed 1,000 - 1,500 feet from the landing threshold of runway 04, which was 7,003 feet in length. The captain utilized aerodynamic braking during part of the landing roll. About 3 seconds after touchdown, the first officer stated, "they're not deployed, they're armed only." About 6 seconds after touchdown, there was an increase in engine rpm. Shortly after that, there was an expletive from the captain. One and a half seconds later, there was another expletive. Slightly less than 2 seconds later, the captain told the first officer to "brake me," and 2.7 seconds after that, stated "emergency brake." About 4 seconds later, there was a "clunk", followed by a decrease in engine rpm 1 second later. Immediately after that, the captain stated, "we're going off the end." The airplane subsequently dropped off an embankment at the end of the runway, impacted and descended through a localizer tower, then impacted the ground and slid across a highway. The airplane had been fitted with a conversion that included thrust reversers. An examination of the wreckage revealed that the thrust reversers were out of the stowed position, but not deployed. The drag chute was also not deployed. Brake calipers were tested with compressed air, and operated normally. Brake disc pads were measured, and found to be within limits. According to an excerpt from the conversion maintenance manual, reverser deployment was hydraulically actuated and electrically controlled. There was also an accumulator which allowed deploy/stow cycling in the event of hydraulic system failure. Interlocks were provided so that the reverser doors could not be deployed until the control panel ARM switch was on, the main throttle levers were in idle position, and the airplane was on the ground with the squat switches engaged. The previous crew reported no mechanical anomalies. Runway elevation rose by approximately 35 feet during the first 2/3 of its length, then decreased until it was 8 feet lower at its departure end. Winds were reported as being from 050 degrees true at 7 knots. At the airplane's projected landing weight, without the use of thrust reversers, the estimated landing distance was about 2,850 feet with the anti-skid operative, and 3,400 feet with the anti-skid inoperative.
Probable cause:
The captain's addition of forward thrust during the landing rollout, which resulted in a lack of braking effectiveness and a subsequent runway overrun. A factor was the captain's inability to deploy the thrust reversers for undetermined reasons.

Circumstances:
While en route at FL370, the pilots declared an emergency, reported a fire in the right engine and requested vectors to the nearest suitable airport. They were vectored toward the Lexington-Blue Grass Airport and circled to descend. Shortly after declaring an emergency, the pilots reported they secured the right engine and extinguished the fire light. As the aircraft was on final approach to land, the local controller (using binoculars) confirmed that both the gear and flaps were extended. However, as the aircraft continued onto a short final approach, an increase in its pitch attitude was noted. It then dropped below the level of the runway threshold and impacted in a pasture short of the runway. After initial impact, the aircraft went thru a stone fence, hit 2 utility poles, crossed a highway, came to rest at the perimeter fence and burned. An auto was damaged by debris; 2 occupants received minor injuries. An investigation revealed the aircraft impacted with the gear extended, but the flaps and flap handle were found in the up position. An examination of the right engine revealed its outer exhaust cone was cracked in the vicinity of a fire detection loop. No other preexisting mechanical problems were evident. Both pilots were killed and both passengers were seriously injured.
Probable cause:
Occurrence #1: airframe/component/system failure/malfunction
Phase of operation: cruise - normal

Circumstances:
As the aircraft was climbing thru 19,000 feet at night, the #2 generator (gen) light came on. The flight crew noted there was no output from the #2 gen and it would not reset. They then checked the #1 gen voltage and noted it was 14 to 15 volts. The crew reduced the electrical load; however, about 5 minutes later, the batteries became discharged and there was a total loss of electrical power. Using a flashlight, the crew diverted to the Chester County Airport which had a 4,600 feet runway. The gear was extended with the emergency system. The elevator trim was inoperative, so both pilots applied back pressure on the yoke to overcome the nose down tendency. After landing about 1/4 of the way down the runway, the crew tried to use the thrust reversers, but the reversers were inoperative. Subsequently, the aircraft continued off the side and beyond the end of the runway, hit a wooden beam and a snowbank, then came to rest in a ditch. An investigation revealed a shaft failure of the #2 gen (starter/gen) and worn brushes in the #1 gen. With total electrical failure, the following were also inoperative: wing flaps, anti-skid, capt's airspeed indicator and altimeter, nose wheel steering, cockpit lighting.
Probable cause:
Occurrence #1: airframe/component/system failure/malfunction
Phase of operation: cruise

Circumstances:
During an ILS to runway 35, the approach was normal until the aircraft was approximately 100 feet above the decision height, except there was condensation on the windshield. Touchdown was hard. A witness said the aircraft landed approximately 1/3 of the way down the 5,200 feet runway. After landing, with the props in 'ground fine,' braking action was ineffective on the wet runway. The aircraft was not equipped with an anti-skid braking system. Subsequently, the aircraft continued off the runway and went down an embankment into a field. Scrub marks on the runway and reverted rubber on the tires indicated the aircraft was hydroplaning. According to the flight manual, 4,500 feet (plus a 10% factor for no anti-skid) would have been required to stop on a dry runway in the prevailing weather conditions, which included a slight tailwind. Two pax, acting as flight attendants (f/a's), assisted the other pax in evacuating. An investigation revealed the f/a's were not properly trained; the pax were not completely briefed before the flight; and the passenger briefing cards were inadequate. The aircraft was on a business flight to transport an entertainment troupe.
Probable cause:
Occurrence #1: overrun
Phase of operation: landing - roll
Findings
1. (f) weather condition - tailwind
2. (f) weather condition - fog
3. (f) weather condition - rain
