Circumstances:
The aircraft was being utilized in support of mineral exploration activities, to transport building materials, fuel, and winter camp supplies from Mayo, Yukon, to winter airstrips located at Withers Lake and Rackla River, Yukon. Withers Lake is located 113 statute miles (sm) east of Mayo, and Rackla Airstrip is located 94 sm northeast of Mayo (Appendix B). On the accident flight, the aircraft was transporting a load of twelve 6-inch by 6-inch wood timbers, each 16 feet long, and 2 barrels of jet fuel. The pilot had arrived at the Mayo Airport at about 0630 1 on the morning of the accident. The pilot’s first trip of the day was to Withers Lake, departing Mayo at 0834. The pilot completed 2 trips to Withers Lake and 1 trip to Rackla prior to the accident flight. The accident flight departed Mayo at 1448 under visual flight rules (VFR) on a company itinerary. At 1507 the Canadian Mission Control Centre (CMCC) received a 406-MHz emergency locater transmitter (ELT) alert. Joint Rescue Co-ordination Centre Victoria (JRCC Victoria) was notified at 1522. Aircraft operating in the area were alerted, and a commercial helicopter was dispatched from Ross River, Yukon, approximately 1 hour later to search for the aircraft. The helicopter crew located the aircraft wreckage at 1833 at about 4300 feet above sea level (asl), on a remote, snow-covered hillside 38 nautical miles (nm) northeast of Mayo.
Probable cause:
The aircraft departed controlled flight for reasons which could not be determined, and broke up due to high speed.

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 privately owned and operated Beech UC45-J was flying out of an outfitter's camp located near Swan Lake, Yukon Territory. The aircraft departed the clay-and-gravel strip for Mayo with one pilot, two passengers, luggage, and a reported load of 800 pounds of moose and caribou meat. The aircraft accelerated down the runway in a normal fashion, with the tail becoming airborne first. The aircraft left the surface of the runway and began a steep climb, followed by a yaw and bank to the left. The aircraft entered the Pleasant Creek valley off the end of the runway in a near-vertical, nose-down attitude. An explosion occurred, followed by a plume of smoke. Two persons immediately attempted to rescue the pilot and the passengers but discovered the aircraft partly submerged in the creek and engulfed in flames from the post-crash fire. There were no survivors.
Probable cause:
Findings as to Causes and Contributing Factors:
1. The meat was loaded into the aircraft on a slippery surface and not adequately secured.
2. The manner in which the meat was loaded and secured most likely allowed the load to shift to the rear of the cabin during take-off. This rearward shift resulted in the loss of pitch control and an aerodynamic stall from which the pilot could not recover.
Other Findings:
1. The aircraft's C of G was most likely at or aft of the aft limit before engine start.
