Circumstances:
The aircraft was on an instrument flight rules flight from the Edmonton City Centre Airport to Kirby Lake, Alberta. At approximately 1114 Mountain Daylight Time, during the approach to Runway 08 at the Kirby Lake Airport, the aircraft struck the ground, 174 feet short of the threshold. The aircraft bounced and came to rest off the edge of the runway. There were 2 flight crew members and 8 passengers on board. The captain sustained fatal injuries. Four occupants, including the co-pilot, sustained serious injuries. The 5 remaining passengers received minor injuries. The aircraft was substantially damaged. A small, post-impact, electrical fire in the cockpit was extinguished by survivors and first responders. The emergency locator transmitter was activated on impact. All passengers were BP employees.
Probable cause:
Findings as to Causes and Contributing Factors:
1. The conduct of the flight crew members during the instrument approach prevented them from effectively monitoring the performance of the aircraft.
2. During the descent below the minimum descent altitude, the airspeed reduced to a point where the aircraft experienced an aerodynamic stall and loss of control. There was insufficient altitude to effect recovery prior to ground impact.
3. For unknown reasons, the stall warning horn did not activate; this may have provided the crew with an opportunity to avoid the impending stall.
Findings as to Risk:
1. The use of company standard weights and a non-current aircraft weight and balance report resulted in the flight departing at an inaccurate weight. This could result in a performance regime that may not be anticipated by the pilot.
2. Flying an instrument approach using a navigational display that is outside the normal scan of the pilot increases the workload during a critical phase of flight.
3. Flying an abbreviated approach profile without applying the proper transition altitudes increases the risk of controlled flight into obstacles or terrain.
4. Not applying cold temperature correction values to the approach altitudes decreases the built-in obstacle clearance parameters of an instrument approach.

Circumstances:
The privately operated Piper PA-46-350P Jetprop DLX (registration C-FKKH, serial number 4622092) had departed from Edmonton, Alberta, at about 0733 mountain daylight time en route to Winnipeg, Manitoba, on an instrument flight rules flight plan. Shortly after the aircraft levelled off at its cleared altitude of flight level (FL) 270, the aircraft was observed on radar climbing through FL 274. When contacted by the controller, the pilot reported autopilot and gyro/horizon problems and difficulty maintaining altitude. Subsequently, he transmitted that his gyro/horizon had toppled and could no longer be relied upon for controlling the aircraft. The aircraft was observed on radar to make several heading and altitude changes, before commencing a right turn and a steep descent, after which the radar target was lost. An emergency locator transmitter signal was received by the Lloydminster, Alberta, Flight Service Station for about 1 ½ minutes before it stopped. The wreckage was found by the Royal Canadian Mounted Police about 16 nautical miles northeast of Wainwright at about 1205. None of the five people on board survived.
Probable cause:
Findings as to Causes and Contributing Factors:
1. The gyro/horizon failed due to excessive wear on bearings and other components, resulting from a lack of maintenance and due to a vacuum system that was possibly not at minimum operating requirements for the instrument.
2. The gyro/horizon was reinstalled into the aircraft to complete the occurrence flight without the benefit of the recommended overhaul.
3. The autopilot became unusable when the attitude information from the gyro/horizon was disrupted.
4. The pilot had not practised partial panel instrument flying for a number of years, was not able to transition to a partial panel situation, and lost control of the aircraft while flying in instrument meteorological conditions.
5. The aircraft was loaded in excess of its certified gross weight and had a centre of gravity (C of G) that exceeded its aft limit. These two factors made the aircraft more difficult to handle due to an increase of the aircraft’s pitch control sensitivity and a reduction of longitudinal stability.
6. The structural limitations of the aircraft were exceeded during the uncontrolled descent; this resulted in the in-flight breakup.
7. There were a number of deficiencies with the company’s safety management system (SMS), in which the hazards should have been identified and the associated risks mitigated.
8. The company did not conduct an annual risk assessment as required by its SMS; this increased the risk that a hazard could go undetected.
9. The Canadian Business Aviation Association (CBAA) audit did not identify the risks in the company’s operations.
Findings as to Risk:
1. Lack of adequate instrument redundancy increases the risk of loss of control in single-pilot instrument flight rules (IFR) aircraft operations.
2. The pilot did not reduce his airspeed while attempting to maintain control of the aircraft; a lower speed would have allowed a greater margin to maximum operating speed (Vmo) while manoeuvring.
3. There were no quick-donning oxygen masks on board and the pilot was not wearing an oxygen mask at the time of the occurrence, as required by regulation.
4. If effective oversight of private operator certificate (POC) holders is not exercised by the regulator or its delegated organization, there is an increased risk that safety deficiencies will not be identified and properly addressed.
Other Finding:
1. The approved maintenance organization (AMO) that was maintaining the aircraft did not have the approval to maintain PA-46 turbine aircraft.

Circumstances:
The Alta Flights Cessna 414A (registration C-GVZE, serial number 414A0219) departed Cranbrook, British Columbia, at approximately 1910 mountain daylight time (MDT) on a visual flight rules cargo flight to Calgary, Alberta. The aircraft disappeared from the Calgary area radar at 1936 MDT, at an indicated altitude of 9000 feet above sea level (asl) in the Highwood Range mountains, approximately 49 nautical miles southwest of Calgary. The aircraft wreckage was found on a mountain ridge at 8900 feet asl some 40 hours later. The flight was in controlled descent to Calgary when the impact occurred. There was a total break-up of the aircraft, and the pilot, the lone occupant, was fatally injured. There was a brief fireball at the time of impact.
Probable cause:
Findings as to Causes and Contributing Factors:
1. The pilot lost situational awareness most likely believing he was over lower terrain.
2. The aircraft was very likely flown into cloud during a day VFR flight, which prevented the pilot from seeing and avoiding the terrain.
Findings as to Risk:
1. The aircraft was not required by regulation to have terrain avoidance equipment installed, leaving the pilot with no last defence for determining the aircraft's position relative to the terrain. This is a risk for all aircraft operated in similar conditions.
Other Findings:
1. The flight plan was prematurely closed by NAV CANADA, which caused the early stoppage of SAR activities and delayed the recommencement of those searches by two hours.
