Positioning

According to witnesses, the airplane collided with two deer shortly after touchdown. Following the collision, the airplane continued down the runway with the tires smoking, veered off the right side of the runway near the end, crossed a taxiway, impacted into a ditch and burst into flames. After the accident, the captain and first officer both reported that the thrust reversers failed to operate after they were deployed during the landing. Examination of the landing gear found all three gear collapsed. The right and left main tires had areas of rubber that were worn completely through. The flaps were found extended, and both thrust reversers were found in the stowed position. Examination of the cockpit found the throttles in the idle position, and the thrust reverser levers in the stowed position. Aircraft performance calculations indicate that the airplane traveled 1,500 feet down the runway after touchdown, in 4.2 seconds, before striking the deer. The calculations also indicate that the airplane landed with a ground speed of 124 knots. At 124 knots and maximum braking applied, the airplane should have come to a complete stop in about 850 feet. However, investigation of the accident site and surrounding area revealed heavy black skid marks beginning at the first taxiway turnoff about 1,500 feet down the 5,010 foot runway. The skid marks continued for about 2,500 feet, departed the right side of the runway and proceeded an additional 500 feet over grass and dirt. The investigation revealed that deer fur was found lodged in the squat switch on the left main landing gear, likely rendering the squat switch inoperative after the impact with the deer, and prior to the airplane’s loss of control on the runway. Since a valid signal from the squat switch is required for thrust reverser deployment, the loss of this signal forced the thrust reversers to stow. At this point, the electronic engine control (EEC) likely switched to the forward thrust schedule and engine power increased to near takeoff power, which led to the airplane to continue down the runway, and off of it. Following the accident, the manufacturer issued an Airplane Flight Manual revision that Page 2 of 8 ATL01FA021 changed the name of the “Inadvertent Stow of Thrust Reverser During Landing Rollout” abnormal procedure to “Inadvertent Stow of Thrust Reverser After a Crew-Commanded Deployment” and moved it into the emergency procedures section.

The aircraft departed Málaga-Pablo Ruiz Picasso Airport at 0543LT on a positioning flight to Córdoba. On board were two pilots who were flying to Córdoba to pick up a medical team for a transplantation mission. Fifteen minutes after takeoff, the crew started the descent but encountered poor visibility due to the night and foggy conditions. At that moment, the horizontal visibility was 300 metres and the vertical visibility about 500 feet. As Córdoba Airport was not equipped with an ILS system, the crew decided to attempt an approach via a GPS system. On final approach, the aircraft was too low, struck a utility pole then crashed onto a uninhabited house located 1,500 metres short of runway 21. The aircraft was destroyed, one pilot was killed and the second was seriously injured.

The twin turboprop airplane overran the runway, impacted two fences, and an occupied automobile after the airline transport pilot attempted to abort a takeoff. The pilot performed a rolling takeoff and was paying close attention to balancing the engine power and keeping runway centerline alignment. As the airplane accelerated, the pilot set the power above 80 percent and began an instrument scan. He then noted the airspeed indicator was reading zero with the needle resting on the peg. After a moment's hesitation, the pilot attempted to abort the takeoff by reducing the power levers to flight idle, and subsequently over the gate to ground fine. He reported to the FAA that he did not place the power controls into the reverse position. Air traffic controllers reported they observed the airplane with its nose wheel off of the ground approximately 3/4 of the way down the 4,602-foot long runway. The aircraft's left and right pitot/static systems were examined and tested after the accident, and no anomalies were noted. The pilot obtained verbal training on rejected/aborted takeoffs for the accident airplane. He obtained his type rating and 14 CFR 135 check-out in the accident airplane approximately 1 month prior to the accident. The pilot had accumulated a total of 10,867.5 hours of flight time, of which 34.7 hours were accumulated in the accident aircraft make and model. The pilot reported his total pilot-in-command flight time in the accident aircraft make and model as 20 hours, all of which were accumulated within the preceding 30 days of the accident. Examination of the airplane, the flight instruments and the pitot/static system found no explanation for the pilot reported lack of airspeed reading. The brakes were found to be fully functional. Review of the performance charts for the airplane disclosed that for the weight and ambient conditions of the takeoff, the airplane required 4,100 feet for an
accelerate-stop distance; the runway was 4,602 feet long.

On September 29, 2000, at 1600 hours local time, a Cessna 340, N130DR, was destroyed when it impacted the water in Nadi Bay, about 1,500 feet short of the runway 09 threshold at Nadi International Airport in the Republic of the Fiji Islands. The commercial pilot, a citizen of the United States and the sole occupant, received minor injuries. Visual meteorological conditions prevailed for the ferry flight, operated by Benchmark Aviation under 14 CFR Part 91, that departed from Magenta Airport, New Caledonia, NWWM at 1200.

After an approach to runway 5, and touched down at 85 knots, the airplane yawed right, exited the runway, the right main landing gear collapsed, and the airplane nosed over. Examination of the airplane revealed that a right main wheel brake had locked up, and the landing gear had collapsed. Inspection of the right main landing gear assembly and all associated components could not provide any determination as to what caused the main wheel brake to lockup. The brake assembly was broken down into its component parts and inspected. No evidence of malfunction could be detected. No contamination of the hydraulic fluid was evident.

The crew departed Freetown-Lungi Intl Airport on a short positioning flight to Freetown-Hastings Airport. After takeoff, during initial climb, the twin engine aircraft entered clouds at an altitude of about 500 feet. While exiting the clouds, the crew noticed a Mil Mi-8 helicopter flying nearby. His crew was completing a local flight on behalf of the UNO. The crew of the Let attempted an evasive manoeuvre but the rotor of the helicopter struck the base of the aircraft's tail. The crew managed to return for an emergency landing but the undercarriage partially failed upon landing. Both pilots escaped uninjured while the aircraft was damaged beyond repair. The crew of the helicopter was able to land safely.

A Cessna 208 Caravan I on amphibious floats, C-GMPB, serial number 20800082, was ferrying members of the Royal Canadian Mounted Police (RCMP) Emergency Response Team from Teslin, Yukon, to a site on the south end of Teslin Lake, British Columbia. At about 1645 Pacific daylight time, three team members, two dogs, and gear were unloaded on a gravel bar across from the mouth of the Jennings River. The aircraft departed for the Teslin airport at about 2355 with the pilot and one RCMP engineer on board. Shortly after take-off, the aircraft was seen to pitch up into a steep climb, stall, then descend at a steep angle into the water. The aircraft was destroyed, and the pilot and the passenger were fatally injured.

The flight had proceeded without incident until a visual approach was made to the destination airport, but a landing was not completed because of poor visibility due to ground fog. The pilot then requested vectors to another airport, and was advised by ATC that he was below radar coverage, and he could not be radar identified. The pilot stated he would proceed to a third airport; he was given a heading, instructed to proceed direct to the airport, and report the field in sight. He was told to over-fly the airport, and might be able to descend through a clearing in the clouds. An inbound air carrier flight reported instrument meteorological conditions on the final approach to a parallel runway. At a location of 1.13 miles east of the airport, the flight, for no apparent reason, turned south, away from the airport. The last radio contact with pilot was after ATC told him his heading was taking him away from the airport and he said he was turning back. The last known position of N201RH was 1.95 miles southeast of the airport, at 500 feet MSL. According to the statement of the passenger that was sitting in the co-pilot's seat, "...all we could see were city lights and darkness underneath us. We were in a right turn, when I saw the trees and subsequently hit it." According to the pilot's log book and FAA records revealed a limitation on his commercial pilot certificate prohibited him from carrying passengers for hire at night and on cross-country flights of more than 50 nautical miles. The records did not show any instrument rating. As per the entries in his personal flight logbook, he had accumulated a total of 1,725.2 total flight hours, 1,550.9 total single engine flight hours, and 184.3 total flight hours in multi-engine aircraft of which 145.6 hours were in this make and model airplane. In addition, the logbooks showed that he had a total of 487.3 cross country flight hours, 61.9 total night flight hours, and 21.6 simulated instrument flight hours.

While descending to Kamina Airport, the twin engine aircraft struck a mountain and crashed. The pilot, sole on board, was killed.

The Learjet departed from an uncontrolled airport about 2 minutes before the accident on a on a VFR climb and was not talking to ATC. The Extra EA-300S departed VFR from a controlled airport and requested and received a frequency change from the control tower 2 minutes after departure. Review of radar data revealed that the Extra climbed to 2,500 feet on a heading of 346 degrees before descending to 2,400 at 1141:25. The Learjet was observed on radar in a right crosswind departure passing through 700 feet on a heading of 242 degrees at 1141:02. At 1141:16, the Learjet was at 1,400 feet heading 269. At 1141:30, the Extra is observed on radar at 2,400 feet, in a right turn heading 360 degrees. The Learjet is observed on radar at 1141:28 in a climbing left turn passing through 2,300 feet. The last radar return on both aircraft was at 1141:30.
