Note: All reported aviation occurrences are assessed by the Transportation Safety Board of Canada (TSB). Each occurrence is assigned a class, from 1 to 5, which indicates the depth of investigation. A Class 5 consists of data collection pertaining to occurrences that do not meet the criteria of classes 1 through 4, and will be recorded for possible safety analysis, statistical reporting, or archival purposes. The narratives below, which occurred between August 1, 2008, and October 31, 2008, are all “Class 5,” and are unlikely to be followed by a TSB Final Report.

— On August 1, 2008, a Rans Coyote S6S aircraft was on climb-out after taking off from the grass Runway 34 at the Greenbank, Ont., airstrip (CNP8) with the pilot and one passenger aboard. At approximately 150 ft above ground level (AGL), the engine (Rotax 912) sputtered, but regained power. The aircraft was then observed in a tight left-hand turn. The turn continued until the aircraft stalled and entered a spin to the left. The aircraft struck the ground in a flat attitude and a fire erupted immediately after ground impact. Both occupants were fatally injured and the aircraft was destroyed. Examination of the aircraft and its flight controls revealed no anomalies. The engine was substantially damaged during the post-crash fire, and no fuel components were recovered for testing. The weather at the time of the occurrence was visual meteorological conditions (VMC). The Greenbank airstrip is surrounded by flat, cultivated farm fields that are suitable for forced landing no mater which direction the aircraft is heading. TSB File A08O0208.

— On August 3, 2008, a privately operated Lake LA-4 amphibian airplane was landing on Harris Lake, Ont., after a local flight. After landing on the water, the airplane struck a boat wake resulting in a swing (water loop) to the right and the right sponson catching the water. The airplane sustained damage to the right wing (sponson bent) and aft fuselage (buckled forward of the empennage). There were no injuries and the airplane was moved to shore. TSB File A08O0212.

— On August 5, 2008, a privately owned Taylorcraft BC-12D with one person on board was conducting a local visual flight rules (VFR) flight from St-Michel-de-Squatec, Que. Upon takeoff, the aircraft struck hydro wires and ended up inverted next to a road. No one was injured. However, a fire broke out after the impact, and the aircraft was destroyed. TSB File A08Q0146.

— On August 6, 2008, an amateur-built Christen Eagle II biplane was landing at the Markle farm airstrip near Claresholm, Alta. The airstrip was mowed to a width of approximately 50 ft and the right edge was bordered by a standing hay crop. The aircraft touched down to the right of centre and during the landing roll, the bottom right wing entered the hay crop. Directional control could not be maintained and the aircraft swerved right, rolled over and came to rest inverted. The aircraft sustained substantial damage; however, the two occupants were uninjured. The Christen Eagle II is a tail-dragger aircraft and the pilot was seated in the rear cockpit; therefore the pilot’s forward view was blocked by the fuselage when the aircraft entered the three-point landing attitude. TSB File A08W0156.

— On August 6, 2008, a Beech 1900C was on a cargo flight from Moncton, N.B., to Montréal/Mirabel, Que. When the crew selected gear down on approach to land at Mirabel, the nose gear indicated IN TRANSIT. After discussion with company dispatch, the crew elected to land on Runway 06R at the Montréal/Pierre Elliott Trudeau International Airport. An emergency was declared and emergency response services (ERS) were in position for landing. The nose gear collapsed on the landing roll. The two crew members exited the aircraft while it was on the runway; they were not injured. Runway 06R was temporarily closed until the aircraft was removed. TSB File A08Q0150.

— On August 9, 2008, the pilot of a Speedwing motorised Delta hang-glider with an 18 m square wing from Air Création, was practicing taxi manoeuvres on Runway 03 at Matagami, Que., when the aircraft suddenly lifted off. The pilot had not yet been trained to fly this type of aircraft and had not intended to take off. He was unable to control the aircraft before it stalled from a height of approximately 60 ft above ground level (AGL). The aircraft landed on its right side, 100 ft from the side of the runway in a ditch. The pilot was seriously injured. The aircraft was destroyed. TSB File A08Q0151.

— On August 11, 2008, a PZL M-18A Dromader aircraft landed at the Moose Jaw, Sask., airport and taxied to the fuel pumps. While taxiing the aircraft into position in front of the fuel pumps, the left wing struck a parked Cessna 182L aircraft. There were no injuries. The Dromader sustained minor damage to the left wing tip and the parked Cessna 182 sustained substantial damage. TSB File A08C0174.

— On August 12, 2008, several hot air balloons took off from St-Jean, Que., during a hot air balloon festival. About 45 min after takeoff, the balloons were forced to land as stormy weather headed in. A Sundance Balloon SBA90 with a pilot and three passengers on board was among one of the balloons that landed. However, after the landing, the pilot ended up outside the basket, leaving the passengers alone on board. The balloon started climbing again, and two of the passengers jumped out of the basket. The balloon continued to climb with the one remaining passenger on board, flew over a power line, and started descending again. The balloon’s flight was finally stopped in a wooded area and with the help of some people on the ground. The three passengers sustained minor injuries; the pilot was seriously injured. The basket was not damaged, but the envelope had tears. TSB File A08Q0153.

— On August 14, 2008, a Robinson R22 Beta helicopter was conducting a training flight with an instructor and a student-pilot on board. During the flare at the end of an autoration, the helicopter blades hit and cut a metal wire. The aircraft landed without further incident. The blades sustained serious damage. No one was injured. TSB File A08Q0155.

— On August 14, 2008, a Bell 206L helicopter was landing near mile 247 on Saskatchewan Hwy 905, when the skid gear became entangled in rocky terrain. The aircraft entered a dynamic rollover condition and sustained substantial damage. The pilot, the sole occupant, was transported to hospital in La Ronge, Sask., treated for minor injuries, and later released. TSB File A08C0175.

— On August 19, 2008, a Cessna 150M took off from the St-Hubert, Que. airport on a training flight with a student-pilot on board. The pilot declared an emergency due to engine trouble and attempted an emergency landing in a field. The aircraft nosed over during the ground run and came to a stop on its back. The pilot was uninjured. An investigation of the aircraft, the engine and its systems revealed no anomalies that could have caused the engine to fail. The temperature and dew point during the flight were in a dangerous icing range and could have caused the engine to fail if the carburetor de-icing procedure was not applied properly. The student-pilot was not very familiar with the carburetor de-icing procedures on Cessna 150-type aircraft. TSB File A08Q0172.

— On August 27, 2008, while lifting off from a clearing 45 NM southwest of Yellowknife, N.W.T., the left skid gear of the Bell 206B helicopter caught on a stump. The helicopter rolled slightly to the left, and tipped backwards. The main rotor blades contacted the ground and severed the tail boom. The helicopter remained upright with the tail down-slope, sustaining substantial damage. There were no injuries to the pilot or two passengers. TSB File A08W0187.

— On September 1, 2008, a Tundra ultralight aircraft was returning to the airport at Vernon, B.C., after a flight to Salmon Arm, B.C. Observers report that when the aircraft was roughly overhead the airport, an unusual noise was heard, the aircraft’s elevators were seen fluttering and the tail boom was seen flexing. Engine power was heard to be reduced, the aircraft banked and the elevator flutter stopped momentarily, but it started again more violently shortly thereafter. Engine power was heard to be further reduced, but at about 200 ft above ground level (AGL) the aircraft rolled inverted and dived into the ground. The pilot received fatal injuries and the aircraft was destroyed. There was no fire. The TSB attended the accident site and provided factual information to support the coroner’s investigation. Wreckage examination determined that the pilot had made several significant modifications to the aircraft, including the installation of a large Lexan elevator trim tab. The trim tab was hinged on its leading edge for only 10 in. of its 18-in. span and was actuated from the pilot’s position by a Bowden cable. The inner wire of the Bowden cable was 0.054 in. in diameter. The outer sheath of the Bowden cable was attached at its aft end to an inch-long post hinged to the trailing edge of the left elevator. Damage to the trim tab and elevator indicate flutter of both control surfaces. The 5-in. diameter aluminium tube (tail boom) that attaches the empennage to the fuselage was fractured through about 80 percent of its diameter. Metallurgical examination determined that the fracture was the result of reverse bending fatigue which occurred after a relatively low number of bending cycles. TSB File A08P0287.

— On September 2, 2008, an amateur-built Super Bee was preparing to land on lac Lepage, Que., in glassy-water conditions. The pilot attempted to pull the aircraft out of its dive because he felt that his rate of descent was too high. The floats struck the surface of the lake hard, and the aircraft immediately nosed over and sank a few minutes later in approximately 40 ft of water. The pilot and the passenger were able to egress and were not injured. They were wearing flotation devices and swam to shore. The aircraft sustained major damage. TSB File A08Q0177.

— On September 3, 2008, as an amateur-built Cargo 4x4 took off, its left float touched a rock on the surface of the water on rivière des Mille Îles near Terrebonne, Que. The aircraft destabilized, went down nose first, ended its run inverted, and ran ashore on Lamothe Island. The pilot was wearing a flotation device and was not injured. TSB File A08Q0174.

— On September 3, 2008, a MD369D helicopter was transporting three passengers from one side of a glacier to the other, about 40 NM north of Stewart, B.C. The weather was overcast, with scattered cloud below (flat light condition). The helicopter struck the glacier in forward flight and nosed over to the right. The helicopter was substantially damaged but there was no fire. The four occupants sustained minor injuries. TSB File A08P0288.

— On September 13, 2008, a de Havilland DHC-2T (Turbo Beaver) on amphibious floats departed the runway at Dease Lake, B.C., with three persons on board for a local flight. The aircraft landed at Level Lake, B.C., where it nosed-over during the landing. All three occupants exited the aircraft and sustained minor injuries. The landing gear was subsequently observed to be in the extended position. TSB File A08P0299.

— On September 24, 2008, a privately owned float-equipped Cessna 180H with two occupants on board took off on a visual flight rules (VFR) flight from Réservoir Gouin, baie Marinette, Que., to the southern bay of Réservoir Gouin. During landing, the right float hit a wood log and split. The aircraft capsized. The two occupants were able to egress and were not injured. They were rescued by a boat immediately after the incident. TSB File A08Q0190.

— On October 7, 2008, a Piper Aztec PA23-250 was conducting a visual flight rules (VFR) flight between Drummondville, Que., and Mascouche, Que. While on the base leg, the pilot, the only one on board, was supposed to follow a Cessna 172 that was executing a touch-and-go. The pilot was focussing on the Cessna 172 and inadvertently forgot to lower the landing gear. The aircraft landed with the landing gear retracted and slid on its belly. The pilot was not injured. The aircraft sustained damage to the landing gear doors, two flaps, propellers and engines. TSB File A08Q0197.

— On October 10, 2008, a Cessna T210G was on final approach to Runway 26 at the Red Lake, Ont., airport. During final approach, the landing gear was not extended and the aircraft landed on its belly. The aircraft came to a rest in an upright position on the centre of the runway. The pilot was not injured, but the aircraft sustained substantial damage. TSB File A08C0210.

— On October 13, 2008, a Cessna 172 was taxiing for takeoff from Runway 06R at Montréal-Pierre Elliott Trudeau International Airport (CYUL). As it approached the Runway 06R holding bay, the Cessna 172 received authorization to go behind a Boeing 777 that was stopped on the left side of the holding bay with jet engines at idle. Once the Cessna was behind the Boeing 777, its left wing and tail were lifted up such that the propeller and right wing struck the ground before the aircraft returned to its normal position. The pilot informed the apron controller and returned to his parking spot to assess the damage. The right wing, engine cowl, and propeller sustained damage. The pilot was not injured. TSB File A08Q0199.

— On October 16, 2008, the pilot of a Bell 206B helicopter was attempting to sling a moose carcass out of the woods, when the sling became caught over the right skid. The aircraft reached an altitude of approximately 20 ft and dynamically rolled to the right and into the Kenogami River, Ont. The helicopter was substantially damaged; there were no injuries.
