Circumstances:
The Black Sheep Aviation and Cattle Company de Havilland DHC-3T Turbo Otter (registration C-GZCW, serial number 447) had been loaded with a cargo of lumber at Mayo, Yukon. The aircraft was taxied to the threshold of Runway 06 and the pilot began the take-off roll at 1755 Pacific daylight time. At lift-off, the aircraft entered an extreme nose-up attitude and began to rotate to the right. Shortly thereafter, the aircraft struck the airport ramp. The pilot, who was the sole occupant of the aircraft, was fatally injured. A small post-impact fire was extinguished by first responders.
Probable cause:
Findings as to Causes and Contributing Factors:
1. The aircraft was loaded in a manner that resulted in the centre of gravity being aft of the rearward limit.
2. Because the cargo was not properly secured, it shifted towards the rear of the aircraft, resulting in the centre of gravity moving further aft, causing the aircraft to pitch up and stall.

Circumstances:
The Air Tindi Ltd. de Havilland DHC-3T (Turbo) Otter (registration C-FXUY, serial number 142) water taxied from the Air Tindi dock at Yellowknife, Northwest Territories, for a charter flight to Blachford Lake. The aircraft was loaded with two crew members, seven passengers, and 840 pounds of cargo. Before the flight, the pilot conducted a preflight passenger briefing, which included information about the location of life preservers and emergency exits. During the take-off run, at about 1912 mountain daylight time, the aircraft performed normally. It became airborne at about 55 mph, which is lower than the normal take-off speed of 60 mph. The pilot applied forward control column to counter the pitch-up tendency, but there was no response. He then trimmed the nose forward, but the aircraft continued to pitch up until it stalled at about 50 feet above the water and the left wing dropped. The aircraft struck the water in the East Bay in a nose-down, 45/ left bank attitude. On impact, the left wing and left float detached from the aircraft, and the aircraft came to rest on its left side. The crew was able to evacuate the passengers before the aircraft submerged, and local boaters assisted in the rescue. There were no serious injuries to the crew or passengers. The aircraft suffered substantial damage.
Probable cause:
Findings as to Causes and Contributing Factors:
1. The aircraft was loaded in such a manner that the C of G was beyond the rearward limit. This resulted in the aircraft’s aerodynamic pitch control limitation being exceeded.
2. A weight and balance report was not completed by the pilot prior to departure and, as a consequence, he was unaware of the severity of the aft C of G position.
Finding as to Risk:
1. The weight of the passengers was underestimated due to the use of standard weights. This increased the potential of inadvertently loading the aircraft in excess of its maximum certified take-off weight.

Circumstances:
The airline transport certificated pilot was conducting a VFR cross-country business flight, transporting cargo and personnel to a remote airport. The accident airplane was one of two airplanes transporting supplies for a hunting/fishing company, traveling a multi-segment route. The pilot was accompanied by a pilot-rated passenger occupying the right front seat, and a second passenger seated behind the pilot. The pilot obtained a weather briefing from the FAA, which included AIRMETs for mountain obscuration, and IFR conditions due to low ceilings and visibility in smoke, light rain and mist. The pilot said that when he took off on the accident flight, the visibility was 1 to 3 miles in smoke, haze, and fog, but was VFR. He recalled hazy conditions in which he could see rolling hills and river cuts. The pilot-rated passenger was initially flying the airplane. Upon entering lowering visibility, the pilot said he reassumed control of the airplane, and attempted a 180 degree turn to clear the low visibility area, but collided with trees and crashed. The rear seat passenger reported that the accident airplane was flying about 500 to 1,000 feet above the ground because of smoke and fog. He estimated the visibility at takeoff was about 1 mile. About 30 minutes after departure, the airplane was flying over mountainous terrain, and appeared to be following a canyon. The passenger said that the visibility decreased due to fog. He said that the airplane's throw-over control yoke was initially positioned in front of the right seat, pilot-rated passenger, when suddenly a mountain ridge appeared in front of the airplane. The pilot repositioned the control yoke in front of the left seat, banked the airplane to the left, and added engine power. Within a few seconds, the passenger indicated that he felt the airplane collide with several trees and then descend to the ground. The airplane came to rest upright with extensive fuselage damage, about 1,400 feet msl. One wing was torn off the airframe. A postcrash fire consumed the wreckage. A terminal forecast for the airport of departure included few clouds at 500 feet, and visibilities as low as 3 miles in smoke and mist. The destination airport for the accident flight segment had few clouds at 100 feet, and visibilities as low as 2 1/2 miles.
Probable cause:
The pilot's inadequate in-flight planning/decision making, his continued VFR flight into instrument meteorological conditions, and his failure to maintain obstacle clearance. Factors contributing to the accident were low ceilings due to smoke, rain, and mist.

Circumstances:
At approximately 0900 eastern standard time (EST), the pilot arrived at the airstrip and prepared the ski-equipped de Havilland DHC–3 (Otter) aircraft (registration C–GOFF, serial number 65) for the morning flight. This Otter was equipped with a turbine engine. Two passengers, with enough supplies for an extended period of time, including a snowmobile and camping gear, were to be flown to a remote location. The pilot loaded the aircraft and waited for the weather to improve. At approximately 1200 EST, the pilot and passengers boarded the aircraft and took off in an easterly direction. The aircraft got airborne near the departure end of the airstrip, and, shortly after take-off, the right wing struck a number of small bushes and the top of a birch tree. The aircraft descended and struck the frozen lake surface, approximately 70 feet below the airfield elevation in a steep, nose-down, right-wing-low attitude. When it came to rest, the aircraft was inverted and partially submerged, with only the aft section of the fuselage remaining above the ice. All of the occupants were wearing lap belts. The pilot and front seat passenger received fatal injuries. The rear seat passenger survived the impact and evacuated the aircraft with some difficulty due to leg injuries. The following morning, about 22 hours after the accident, a local air operator searching for the missing aircraft located and rescued the surviving passenger.
Probable cause:
Findings as to Causes and Contributing Factors:
1. The pilot attempted to take off from an airstrip that was covered with approximately 18 inches of snow, and the aircraft did not accelerate to take-off speed because of the drag; the aircraft was forced into the air and was unable to climb out of ground effect and clear the obstacles.
2. The pilot did not abort the take-off when it became apparent that the aircraft was not accelerating normally and before the aircraft became airborne.
Findings as to Risk:
1. Unidirectional G switches, which are found on many types of ELTs, do not always activate the unit when impact forces are not aligned with the usual direction of flight.
Other Findings:
1. The validity of the aircraft’s certificate of airworthiness was affected while it flew more flights than allowed by the ferry permit issued by Transport Canada.
2. The rear passenger seat was found to be installed incorrectly, contrary to de Havilland Alert Service Bulletin A3/49, dated 19 July 1991.

Circumstances:
The commercial certificated pilot reported that just after takeoff in a wheel/ski equipped airplane, he heard a very loud bang, followed by a loud rattling noise. As he turned towards the departure airstrip, he had difficulty using the airplane's rudder pedals. Using a combination of aileron input and the remaining amount of rudder control, he was able to maneuver the airplane for a landing on the airstrip. He said that as the airplane passed over the approach end of the airstrip, it drifted to the right, and he initiated a go-around. The airplane subsequently collided with a stand of trees bordering the airstrip, and sustained structural damage to the wings, fuselage, and empennage. In a written statement to the NTSB, the pilot stated that he suspected that the right elevator's outboard and center hinges or hinge pins failed, allowing the right elevator to swing rearward and jam the airplane's rudder. An FAA airworthiness inspector traveled to the accident scene to examine the airplane. He reported that the right elevator was discovered about 150 feet behind the airplane, within the wreckage debris path through a stand of trees. He said that the right elevator sustained a significant amount of damage along the leading edge, which would normally be protected by the horizontal stabilizer. The FAA inspector examined the airplane's horizontal stabilizer in the area where the right and left elevators connect, and noted signs of new paint on the rivets that held the torque tube support assembly, indicating recent reinstallation or replacement of the torque tube support assembly. He indicated that the torque tube support assembly was installed at a slight angle to the right, which allowed the right elevator to eventually slip off of the center and outboard hinge pins. The inspector said that witness marks on the center and outboard hinge pins showed signs of excessive wear towards the outboard portion of each pin. The inspector noted that a review of the airplane's maintenance records failed to disclose any entries of repair/replacement of the elevator torque tube support assembly.
Probable cause:
An improper and undocumented major repair of the elevator torque tube support assembly by an unknown person, which resulted in an in-flight disconnection of the airplane's right elevator, and a jammed rudder. A factor associated with the accident is the inadequate inspection of the airplane by company maintenance personnel.

Circumstances:
A de Havilland DHC-3 Otter owned by Deraps Aviation Inc., registration C-FLGA, serial number 279, took off from Lake de l'Avion, Quebec, near Natashquan Airport at approximately 1050 eastern daylight time on a flight to a hunting camp 57 miles to the north along the Aguanish River. The pilot and three passengers were on board. Upon arriving at the destination at approximately 1135, the aircraft flew over part of the neighbouring forest before crashing upside down on rugged ground. The passengers were fatally injured on impact. The pilot survived and was evacuated to Sept-Îles by Canadian Forces Search and Rescue services at approximately 0400 on 29 September 2002.
Probable cause:
Because of the geographic and weather conditions, the pilot probably had trouble judging his horizontal and vertical distance with respect to the mountain, and the aircraft crashed.
