Circumstances:
The private pilot arrived at the accident airport as part of an Angel Flight volunteer program to provide transportation of a passenger who had undergone medical treatment at a local hospital. About 0937, the airplane landed on runway 30 (3,900 feet by 150 feet) with winds from 073-080 degrees and 5-6 knots, which continued to increase due to an atmospheric pressure gradient. The pilot met the passengers and departed the terminal about 1003, with winds at 101-103 degrees and 23-36 knots. About 1005 the airplane was near the approach end of runway 30 with wind from 089-096 degrees and 21-31 knots. The pilot stated that he began rotating the airplane about 3,000 feet down the runway. About 1006, the airplane was approximately 3,553 feet down the runway while flying about 30 feet above the runway. The airplane experienced an aerodynamic stall, and the left wing dropped before it impacted the ground. No mechanical anomalies that would have precluded normal operation of the airplane were noted during the investigation. The fatally injured passenger, who had received medical treatment, was 2 years and 10 months of age at the time of the accident. She was held by her mother during the flight, as she had been on previous Angel Flights, but was otherwise unrestrained. According to 14 CFR 91.107(3), each person on board a U.S.-registered civil aircraft must occupy an approved seat with a safety belt properly secured during takeoff, and only unrestrained children who are under the age of 2 may be held by a restrained adult. Although the accident was survivable (both the pilot and the adult passenger survived with non-life-threatening injuries), an autopsy performed on the child revealed that the cause of death was blunt force trauma of the head.
Probable cause:
The pilot's improper decision to depart with a preexisting tailwind and failure to abort takeoff. Contributing to the severity of the injuries was the failure to properly restrain (FAA-required) the child passenger.

Circumstances:
The crew was performing a local training flight at Decatur Airport, consisting of touch-and-go maneuvers. On final approach to runway 24, the instructor elected to simulate a failure of the right engine. Anticipating the touch-and-go procedure, the instructor deactivated the yaw damper system while the aircraft was about 10-20 feet above the runway. As the speed increased, the instructor called out 'speed' twice when the copilot reduced the power on the left engine. The aircraft rolled to the right, causing the right wingtip to struck the ground. The aircraft went out of control, veered off runway and came to rest, bursting into flames. Both pilots escaped with minor injuries while the aircraft was destroyed.
Probable cause:
The crew’s failure to take appropriate action after allowing the aircraft to get 15 knots [17 mph] slow over the runway threshold. Had either pilot taken proper action to go around upon seeing the airspeed bleeding away by advancing power on both engines, this mishap could have been avoided.

Circumstances:
The airplane collided with trees and terrain following a loss of control during an Instrument Landing System (ILS) approach at night. The impact occurred approximately 2.1 miles from the approach end of the runway. A witness reported hearing the airplane at "mid-throttle" as it flew over. He then heard the power increase followed by the impact. The witness stated there was no precipitation at the time of the accident and there were "severe winds, mostly from the south, shifting volatile directly from the east." He also stated the visibility was "extremely poor." Statements were received from five pilots who landed in transport category airplanes around the time of the accident. Three of these pilots reported experiencing a crosswind that varied from 15 to 50 knots during the approach. Four of the pilots reported airspeed fluctuations that varied between +/- 8 knots to +/- 10 knots during the approach. Three of the pilots reported breaking out of the clouds between 200 and 300 feet agl. Radar data indicates the airplane was high on the glideslope until it entered a rapid descent from an altitude of about 2,300 feet. Examination of the airframe, engine, and propeller governors failed to reveal any failures/malfunctions that would have resulted in the loss of control.
Probable cause:
The pilot's failure to maintain control of the airplane during the ILS approach. Factors associated with the accident were the low ceilings, high winds, crosswind, and wind shear conditions that existed.

Circumstances:
The pilot and 21 jumpers were aboard the airplane for the local skydiving flight. The airplane took off to the north on the wet grass runway. Jumpers reported that during the initial takeoff climb, the aircraft assumed a "very steep angle of attack," and described the pilot "winding the wheel on the lower right side of the chair clockwise, frantically," and "busy with a wheel between the seats." The airplane impacted trees and terrain approximately 250 yards east of the runway. The pilot reported that the "airplane flew through a dust devil" and did not have enough altitude for a complete recovery. The pilot stated the winds were northerly at 6 to 8 knots with "extreme" turbulence. The nearest weather observation facility reported clear skies with calm wind. Takeoff weight and center of gravity (CG) were calculated at 9,118.05 lbs and 161.92 inches. The AFM listed the maximum gross weight at 8,000 pounds and the aft CG limit at 152.2 inches. Further, an AFM WARNING stated: C. G. POSITION OF THE LOADED AIRCRAFT MUST BE CHECKED AND VERIFIED PRIOR TO TAKE-OFF, AND APPROPRIATE TRIM SETTINGS SHOULD BE USED; OTHERWISE ABNORMAL STICK FORCES AND POSITIONS MAY RESULT. The elevator trim wheel is located on the righthand side of the pilot's seat. Post-accident examination of the airplane revealed that there were 16 seatbelts in the cabin section and 2 seatbelts in the cockpit. Additionally, a placard installed in the cockpit stated, in part, THIS AIRPLANE IS LIMITED TO THE OPERATION OF NINE PASSENGERS OR LESS. Regarding the discrepancy between the placarded 9 passenger limit and the 21 jumpers aboard, the pilot stated that parachute jumpers are not considered to be passengers and therefore, he did not have to comply with the placarded limit.
Probable cause:
The pilot's failure to maintain aircraft control during the takeoff/initial climb. Contributing factors were the pilot's exceeding aircraft weight and balance limits and the dust devil.

Circumstances:
Departed Marion without a weather briefing. Pilot advised during approach that last person making approach reported moderate to severe turbulence on final. Subsequently cleared to land and given wind 360 at 30 gusting 40. Also advised that another aircraft reported a 20 knots windshear on final. The pilot reported that when he had descended to 1,500 feet msl, the aircraft encountered strong turbulence and the airspeed went from stall to redline. Despite adjustment to flaps and throttle, the airplane was uncontrollable.
Probable cause:
The pilot's intentional flight into known adverse weather. Contributing factors were the pilot's poor evaluation of the weather information given him by the air traffic controllers.

Circumstances:
During a return flight at night to Decatur, AL, the pilot noted his weather radar was inoperative. He visually avoided thunderstorms (tstms), which had been forecasted. While avoiding tstms, he noted a reduction in engine power, a slight yaw, indications of fuel flow irregularity and that the left and right boost pumps were inoperative. These occurred at about the time, he saw a white arc which he said had jumped from the prop, spinner or nacelle area to the aircraft's nose. Due to the weather, he elected to divert to Paducah. After the airport was in sight, he needed to lose altitude before landing and was cleared to make a 360° turn. While turning, he lost sight of the airport, then rolled out on the wrong heading and started flying toward a strobe light at an industrial complex. When he realized his error and saw the airport, he turned toward the runway; but as he was maneuvering, the aircraft lost altitude, hit trees and crashed. An examination of the engines and fuel pumps revealed no indication of a preimpact failure. No physical evidence of a lightning strike was found, but the nose and engines were badly damaged from impact.
Probable cause:
Pilot failed to maintain proper altitude while maneuvering to land. Probable contributing factors were inoperative weather radar, thunderstorms, lightning, an undetermined electrical problem, dark night, the pilot's improperly planned approach and visual perception, and the trees.

Circumstances:
The aircraft crashed into the side of a mountain ridge during a VFR attempt to land at an airport with no instrument approach. The mountain ridge was obscured by broken clouds. The pilot had cancelled his IFR clearance, and during the descent to the airport, he had descended below clouds near the airport with clouds still obscuring some of the terrain. One mile visibility was a requirement for the VFR approach. According to witness statements, the aircraft continued to remain below the clouds and the pilot continued the approach even though he was not properly positioned to make a successful landing. The pilot had a partial occlusion of a coronary artery, but its relationship to the accident was not determined. The aircraft impacted at about 6,250 feet msl. The field elevation is 5,315 feet msl. The accident site was about 2 1/2 mi from the airport. The airport was located in a mountain valley about 1 to 1.25 mi wide. Also, the airport and surrounding terrain were covered with snow. Both pilots were killed.
Probable cause:
Occurrence #1: in flight encounter with weather
