After lift-off, at about 100 ft agl and 85 kts, the left eng decelerated and the airplane began to yaw and roll left. The pic aborted the takeoff, turned left and landed on a flat level field. The airplane struck a fence, then trees. Examination of the left eng revealed the loss of power was attributed to a fatigue fracture of a compressor turbine blade, which led to subsequent blade fractures. The right eng was examined and found to have advance wear on the throttle cam assembly of the power turbine governor. In a test cell, only aprx 28% of takeoff power could be achieved. The cam lobe wear had progressed over an extended period of time. The right engine prop governor was replaced 11/18/90, followed by a test run.
Category: Accident Type
The airplane collided with trees and power lines during takeoff from a 2000 foot long open area with 10 parachutists aboard. The pilot said he experienced an unsolicited rollback in engine power prior to the collision. Reportedly, some power was regained. However, not in time to avoid the collision. But, the jump club chairman reported that no change in the engine’s operation was observed throughout the mishap. Witnesses at the takeoff area reported that the winds were 12 knots out of the northeast, which would have given the flight a quartering tailwind component for the takeoff. According to the flight manual, the maximum demonstrated crosswind is 12 knots. The examination of the airplane failed to indicate any system malfunction or failure.
The aircraft crashed about 600 feet short of the threshold of the runway. Witnesses observed that the engine had been ‘cutting in and out’ before the crash. A photograph taken at the crash site showed the fuel selector handle displaced between the left main position and the both position.
Both aircraft were involved in a movie operation with the helicopter (n250ca) carrying a camerman. The dhc-6 (n203e) carried parachutists. The purpose of the operation was to photograph the parachutists exiting the jump aircraft. The pilot of n250ca said he was in formation with n203e and was maneuvering into camera position when the rotor blades contacted the vertical stabilizer and rudder of n203e. The pilot of n203e was not in a position to have visual contact with the helicopter.

After climbing out of the aircraft on his first jump, the skydiver froze on the lift strut of the aircraft. The jumpmaster deployed his chute, intentionally pulling him off the aircraft. The chute deployed above the horizontal stabilizer, the skydiver went below. The canopy lines (4) were dragged across the horizontal stabilizer cutting the lines and damaging the stabilizer. The skydiver received serious injuries on landing in a field. The pilot was able to make a precautionary landing with no additional damage.
The wing flaps jammed in the mid range position. The parachutist on board exited the airplane and the pilot returned for a landing. He extended the traffic pattern and while on base leg, the engine lost power. He was unable to get the engine restarted and was beyond gliding distance to the airport. The pilot executed an off airport landing in a field, downwind. The faa reported the flaps were jammed due to a broken flap support on the inboard left flap track and the engine was test run satisfactory after the accident. Fuel was reported to be at the 1/4 level. The power loss was attributed to the fuel selector being improperly position.
Aircraft was attempting to land by use of vehicle lights. The aircraft touched down in soft terrain to the right of the runway and nosed over.
After completing a parachute drop, the pilot was returning to the airport for landing. The pilot applied carburetor heat while descending to the pattern, but turned it off during the extended down wind. When on short final, the engine suddenly lost power. The pilot was unable to land the airplane on the airport and initiated a forced landing in an open field. During the landing roll, the airplane nosed over. Examination of the engine did not reveal evidence of mechanical failure or malfunction.
The pilot of the cessna 182 was descending in a right turn after dropping parachute jumpers at 4500 ft msl. As he descended below 1500 ft msl, his aircraft collided with a beech a36. The a36 had departed from the queen city airport and was in the traffic pattern to land at the airport when the collision occurred. The cessna crashed in a paved parking lot of a shopping center and the beech crashed into a new car dealership’s parking lot. Both aircraft were destroyed along with several cars in the dealership’s lot.
The pilot reported that he detected a loss of power during the desent to land that carburetor heat seemed to correct. He discontinued the carburetor heat after a short period of time and the engine failed on final approach at approximately 500 feet agl. The icing probability chart indicates that existing conditions were conducive for carburetor icing and the spark plugs showed evidence of an over rich condition. The engine ran without problem when installed on another aircraft.
The plt was returning to land after hauling skydivers. He rprtd that while on a short final apch to land on rwy 31 with 20 to 30 deg of flaps extended, the acft entered a high sink rate in gusty wind conditions. He said that he lowered the nose to increase speed & that he planned to arrest the sink rate in the flare, but then ‘the bottom fell out’ & the acftcollided with the ground in a nose low attitude. The flt manual recommended that if the rwy length permitted, crosswind landings should be performed with the flaps retract. The manufacturer estimated that 560 ft would have been required to land the acft on a hard surface with no wind & 40 deg of flaps. The rwy length was 2800 ft. The plt rprtd the wind was variable from 240 to 270 deg with gusts to 20 kts. Aprx 20 mi southeast at shaw afb, the 1655 edt wind was rprtd to be from 260 deg at 20 gusting 28 kts.
As the acft was climbing thru 9,000 ft for 13,000 ft with skydivers aboard, the eng lost power from fuel exhaustion. The skydivers bailed out over the drop zone, then the plt attempted to return to the arpt from about 7000 ft. An emergency landing was made before reaching the rwy. The plt saw a fence ahead & applied heavy braking to avoid hitting the fence. However, the acft encountered a ditch as the plt was applying brakes & the acft nosed over.
Accident airplane was being used for sport parachute activity when engine failed during the initial climb of a jump sortie. The pic instructed his four skydiver passengers to assume a crash position and accomplished an off airport landing in a soft field. During the landing roll the nose landing gear collapsed. Post accident examination of the engine revealed a piece of duct tape obstructing the carburetor venturi restricting airflow to the engine.
The plt rprtd his apch speed was slightly fast & that he had landed long on the 2500′ grass strip. Subsequently, he was unable to stop the acft before it struck a snowbank at the end of the strip & it nosed over. The selected runway was aligned to the south. The wind was rprtd to be from the west at about 15 kts. Also, the grass strip was described as ‘slippery’ with patches of snow/ice.
Having just made a parachutist’s drop, during a sky diving operation, the private pilot spiraled down from altitude to land, but had to extend his pattern to allow a departing acft to leave. During a long final approach, the engine failed and an emergency landing was attempted in a soft plowed farm field. The acft, on landing, dug in it’s nose wheel and turned over. No mechanical or fuel irregularities were discovered during the post accident investigation and meteorological conditions were favorable for carburetor icing according to the ‘icing probablility charts’.
The pilot and three passengers were on a night flight in an aircraft that was equipped to carry skydivers. During the approach to land, the landing light failed. While attempting to get the light to operate, the pilot allowed an undershoot to develop. Subsequently, the aircraft landed short of the runway and the nose gear failed when the nose- wheel struck the runway lip. The aircraft then slid approximately 300 feet and nosed over. Mirl & threshold lights were installed, but there were no vasi lights.
The airplane landed uneventfully after a skydiver struck the horizontal stabilizer following an inadvertent deployment of his main parachute as he was preparing to exit the airplane. The skydiver was not injured and descended normally.
During a local parachute jump flight, the airplane was unable to gain enough altitude to clear rising terrain. The airplane collided with a tree and eventually the terrain. There were no reported mechanical failures or malfunctions. The acft handbook lists 2307 lbs as max gto wt. The acc acft weighed 2280 lbs. The cg was in the rear third of the envelope at aprx 103.35. The da was aprx 6200 ft.
While attempting to takeoff from a 1,865′ turf runway on an 85 degree day with four sky divers/passengers on board, the pilot was unable to attain sufficient airspeed for lift-off and elected to abort the takeoff. The pilot estimated that he had used about 60 – 70% of the runway before initiating the remedial action, and could not stop the aircraft before the end of the runway. It ran off the departure end of the runway, across a road, into a ditch, and then nosed over.
After dropping skydivers the pilot entered a descent to return to the airport for another load of jumpers. He was receiving radar advisories during the drop from a tracon controller. As the aircraft descended below 4,000 feet msl the controller terminated the radar advisory service. Immediately after the controller discontinued the service he asked the pilot to check for a stuck microphone switch. The aircraft continued its descent and collided with a camping trailer and building under construction in an extreme nose low attitude. The elevator trim was found in the full nose down position. No other malfunctions were found.
The plt dropped off parachutists at 8,500 ft and began to descend back to arpt. The a/c was descending at 145 mph, 19 inches mp, and 2300 rpm in a long circular pattern. The flt was on final between 500 and 1000 ft msl when the plt tried to apply pwr. The eng failed to respond. After switching the fuel selector and attempting to restart the eng twice, the plt decided to lnd in a field short of the runway. During landing roll, the nose gear broke off and the a/c nosed over. Later the eng was operated to full pwr with no evidence of failure or malfuction. Calculations indicated enough fuel for operation and fuel was found in carb bowl. According to icing probability curves, the a/c was flying in conditions conducive to carb icing. The plt stated that carb heat was not applied during descent.
The airplane lost power shortly after takeoff, at 100-200 ft agl. A witness reported hearing the engine backfire several times before it lost power completely. The airplane crashed shortly thereafter, as the pilot was attempting to return to the arpt. Exam of the engine revealed that the ignition harnesses and several spark plugs were in poor condition: several ignition leads were deteriorated; 3/4 of all leads were improperly connected to the magnetos. The spark plugs fired intermittently and broke down under pressure, when operationally tested. Other evidence of poor maintenance was also found, including water contamination in the carb bowl and a deteriorated carb accelerator pump. The airplane underwent a 100 hr inspection 4 months/128 flt hrs before the accident.
A commercial plt was flying a group of parachutists for a skydiving club. The aircraft encountered turbulence during a climb to 4,500 feet agl. As the second jumper was exiting, the aircraft dropped and the parachutist struck the horizontal stabilizer. The outer four inches were bent downward and the assembly was pulled one inch from the fuselage. The plt made a normal landing and an inspection revealed some bulkhead damage in the tail section. The parachutist was not injured.
The plt rprtd that the left main gear collapsed as he started to taxi from the ramp area on a smooth grass surface. When the gear collapsed, the left wing dropped to the ground & was substantially dmgd. The plt rprtd the left gear leg had broken off 2 inches ‘inside the bulkhead.’ an exam of the broken part revealed it had failed from fatigue.
