Embraer EMB-110 Bandeirante

After conducting ground training all day, the instructor/director of operations and his trainee flew an EMB-110P1 to Memphis to exchange airplanes. Ground fog had started to form prior to departure. After exchanging airplanes, they made the return flight to Columbia. They obtained radar vectors to the final approach course for the SDF at Columbia. The thick fog resulted in a missed approach. During the missed approach, the runway was visible from above and the crew indicated that they would try for a VFR approach and landing. The airplane collided with trees 2,350 feet from the runway in a wings level attitude. The tops of the trees were broken 41 feet above the runway threshold altitude. The trainee had been without rest for at least 30 hours prior to the accident. One pilot was killed while the second was seriously injured.

Shortly after the initial power reduction during takeoff, the pilot noted a partial loss of power in the right engine. He said he 'went to full power on both engines' and noted an 'extremely high' fuel flow indication to the right engine. He said, 'thinking that the engine was flooding, I placed the boost pump switch from high to off to possibly eliminate the problem with no result. I then placed the pump back to high and tried to decrease the fuel flow by leaning the mixture. This also did not seem to eliminate the problem.' While troubleshooting the problem, he turned to a downwind and stayed in the traffic pattern, but could not maint altitude. Subsequently, a wheels-up landing was made in an area of small trees approximately 1/2 mile before reaching runway 24. An examination of the right engine revealed the spark plugs were wet with fuel and black with soot. Also, its #5 fuel nozzle had been cross-threaded and was knocked out of its hole during impact. During an initial test, the right fuel pressure sensing switch did not sense operating pressure (over 6 psi); this would have resulted in a high boost/fuel flow condition. Later, the switch was tested ok. All nine occupants escaped uninjured.

At 18:12, flight 1039 was cleared for takeoff from runway 31. At 18:13, while over the departure end of the runway and climbing through 600 feet, the crew acknowledged a frequency change. Thirty seconds later, the airplane was seen in a steep a descent near the extended centerline of the runway. The Bandeirante struck the ground 7,800 feet beyond the departure end of runway 31 and 85 feet to the right of the extended runway centerline in an inverted nose down attitude, after which it caught fire and burned. Before ground impact, the horizontal stabilizer, including bulkhead No. 36, had separated from the fuselage. Both elevators and elevator tips, the tail cone assembly, and the aft portion of the ventral fin also had separated in flight. All 13 occupants were killed.

Shortly after takeoff, both engines lost power and a wheels up landing was made in an open field. The aircraft was destroyed by impact and fire. An investigation revealed that the aircraft had been refuel with Jet-A fuel rather than 100 low lead avgas. The lineman had inadvertently used the Jet-A fuel truck which was identical to the Avgas truck except for a decal, appx 4' by 16', which identified the type of fuel. The lineman stated that his training consisted of approximately 30 minutes of reading the company maintenance manual on how to refuel the different company aircraft, then was given on-the-job training for a brief time. When he went to refuel N89PB prior to the accident flight, he went to the parking space where the Avgas truck was normally parked, but on that occasion, the Jet-A fuel truck was there.

During arrival, the flight was cleared for an ILS/DME approach to runway 27. While on the approach, the aircraft crashed in the ocean about 2.7 miles east of the runway threshold. The pilot reported that he was making the approach, using instruments, and landed short for unknown reasons. He received a serious head injury, but was rescued by fishermen who heard the aircraft crash and went to where they heard the voices of the victims in the fog. The 0835 weather at Boston was in part: partial obscuration, 25,000 feet overcast, 4 miles visibility with fog and haze, wind from 140° at 7 knots. Other pilots reported low ceilings and a fog bank in the vicinity of the crash site. The captain survived while the copilot died.

While approaching Marshfield Airport from the northeast, the right engine failed. The pilot increased power on the left engine but as he was unable to maintain a safe altitude, he ditched the aircraft off Humarock. All 14 occupants were quickly rescued while the aircraft later came to rest onto the beach and was damaged beyond repair.
