Canada

Findings as to causes and contributing factors:
- It is likely that the PROBES AUTO/MANUAL switch was inadvertently moved from the AUTO to the MANUAL selection when the centre pedestal cover was removed.
- The PROBES AUTO/MANUAL switch position check was not included on the Newfoundland and Labrador Government Air Services CL-415 checklist.
- The flight crew was occupied with other flight activities during the scooping run and did not notice that the water quantity exceeded the predetermined limit until after the tanks had filled to capacity.
- The flight crew decided to continue the take-off with the aircraft in an overweight condition.
- The extended period with the probes deployed on the water resulted in a longer take-off run, and the pilot flying decided to alter the departure path to the left.
- The left float contacted the surface of the lake during initiation of the left turn. Aircraft control was lost and resulted in collision with the water.
Findings as to risk:
- If safety equipment is installed in a manner that hampers its access and removal, then there is an increased risk that occupants may not be able to retrieve the safety equipment in a timely manner to ensure their survival.
- If individuals are not trained on safety equipment installed on the aircraft, then there is an increased risk that the individuals may not be aware of how to effectively use the equipment.
- If a checklist does not include a critical item, and flight crews are expected to rely on their memory, then there is a risk that that item will be missed, which could jeopardize the safety of flight.
- If flight crews do not adhere to standard operating procedures, then there is a risk that errors and omissions can be introduced, which could jeopardize the safety of flight.
- If a person is not restrained during flight and the aircraft either makes an abrupt manoeuvre or loses control, then that person is at a much greater risk of injury or death.
- If an overweight take-off is carried out, there may be an adverse effect on the aircraft’s performance, which could jeopardize the safety of flight.
- If companies do not have procedures for recording overweight take-offs and flight crews do not report them, then the overall condition of the aircraft’s structures will not be accurately known, which could jeopardize the safety of flight.
- If organizations do not use formal and documented processes to manage operational risks, there is an increased risk that hazards will not be identified and mitigated.
- If organizations do not have measures in place to raise awareness of the potential impact of stress on performance or to promote the early recognition and mitigation of stress, then there is an increased risk that errors will occur when an individual is affected by stress that has become chronic.
Other findings:
- Utilizing the locking position of the PROBES AUTO/MANUAL switch for the MANUAL selection allows the switch to be inadvertently moved from the AUTO to the MANUAL position.

Findings as to causes and contributing factors:
- The pilot relied exclusively on the gauge readings to determine the quantity of fuel on board, without cross-checking the fuel consumption since the last fueling to validate those gauge readings.
- The pilot misread the fuel gauges and assumed that the aircraft had enough fuel on board to meet the minimum fuel requirements of the Canadian Aviation Regulations for this visual flight rules flight, rather than adding more fuel to meet the greater reserves required by the company operations manual.
- The pilot did not monitor the fuel gauges while in flight and decided to extend the flight to carry out a practice instrument approach with insufficient fuel to complete the approach.
- The right engine stopped due to fuel exhaustion.
- The pilot did not carry out the approved engine failure procedure when the first engine stopped, and the propeller was not feathered, resulting in significant drag which reduced the aircraft's gliding range after the second engine stopped.
- The pilot continued flying toward Montréal/St-Hubert Airport (CYHU), Quebec, despite having advised air traffic control of the intention to divert to the St-Mathieu-de-Beloeil Airport (CSB3), Quebec, and without communicating the emergency. The priority given to communications resulted in the aircraft moving farther away from the intended diversion airport.
- The left engine stopped due to fuel exhaustion 36 seconds after the right engine stopped, when the aircraft was 7.4 nautical miles from Runway 24R at Montréal/St-Hubert Airport (CYHU), Quebec, and 2400 feet above sea level.
- The pilot's decision to lower the landing gear while the aircraft was still at 1600 feet above sea level further increased the drag, reducing the aircraft's gliding range. As a result, the aircraft was not able to reach the runway at St-Mathieu-de-Beloeil Airport (CSB3), Quebec.
- The operations manager was unable to perform the duties and responsibilities of the position related to monitoring and supervision of flight operations. As a result, the safety of more than half of the flights was compromised.
Findings as to risk:
- If the total fuel quantity required for a flight is not calculated and clearly displayed on the operational flight plan, there is an increased risk that aircraft will depart without the fuel reserves required by the Canadian Aviation Regulations.
- If flights are planned and carried out without the fuel reserves required by the Canadian Aviation Regulations, there is an increased risk of fuel exhaustion resulting from unanticipated situations that extend the duration of the flight.
- If pilots elect to extend flight without first determining whether sufficient fuel reserves are available to do so, there is an increased risk of fuel exhaustion.
- If pilots do not regularly check the quantity of fuel on board, there is an increased risk of fuel exhaustion.
- If pilots do not rule out a fuel leak before opening the crossfeed valve, they risk losing all of the remaining fuel on board.
- If a pilot does not maintain control of an aircraft until landing, the force of an impact following an aerodynamic stall is likely to be far greater, increasing the risk of injury or death during a forced landing.
- If a pilot does not declare an emergency to air traffic control in a timely manner, the pilot may be deprived of assistance and resources that could help deal with the emergency, increasing the risk of an accident.
- If pilots do not receive training in dealing with complex emergencies that require prioritizing tasks, there is a risk that they will not react effectively to emergencies, increasing the risk of an accident.
- If companies do not establish a process to monitor the performance of their pilots during training and testing, there is a risk that those companies will inadvertently assign pilots to carry out flights for which they are not proficient.
- If a flight is planned and authorized solely by the pilot, with no cross-check for compliance with existing regulations, there is a risk that deviations will continue undetected, reducing the safety of the flight.
- If pilots operate without regular supervision to ensure compliance with regulations and company procedures, coupled with effective training, there is a risk of procedural adaptations that result in reduced safety margins.
- If companies assign inexperienced personnel to key flight operations management positions, there is a risk that deviations in performance or from regulations will not be detected, reducing the safety of flight operations.
- If the pilot proficiency check requirements for a chief pilot are not more stringent than those for other pilots, there is a risk that the chief pilot will be unable to perform the duties required to ensure the safety of company training and operations.
- If the approval process for appointment of operations management personnel by companies is reduced to a compliance checklist based on the minimum standards in the Commercial Air Service Standards and on pilot proficiency checks that may be repeated an unlimited number of times, there is a risk that candidates who are unfit to perform the duties and responsibilities of their positions will be appointed.
- If Transport Canada does not take into consideration the combined knowledge and experience of a new operator's management team, there is a risk that the operator will lack the skills necessary to ensure the safety of flight operations.
- If process inspections carried out by Transport Canada do not examine factors related to a recent occurrence, there is a risk that those hazardous conditions will go undetected and will persist.
If process inspections carried by TC on newly certificated operators do not closely examine the outcomes of company processes, there is a risk that hazardous conditions will not be identified and will persist.
- If the inability of appointed individuals to perform their duties and responsibilities does not constitute grounds for suspending or revoking the ministerial approval of such appointments, there is a risk that operations management personnel who are not competent will remain in their positions, increasing the risk to flight safety.
Other findings:
- The chief pilot did not meet the requirements of the Canadian Aviation Regulations at the time of appointment.
- There was no indication that the aircraft's fuel gauges were not functioning properly at the time of the occurrence flight, and it is unlikely that a deviation of the fuel gauge indicator was a factor in the pilot's decision to take off.
- C-GJSU had approximately 260 pounds of fuel on board when it took off from Montréal/St-Hubert Airport (CYHU), Quebec, and did not experience a fuel leak during the occurrence flight.

Findings as to causes and contributing factors:
1. The lack of required flight documents, such as instrument approach charts, compromised thoroughness and placed pressure on the captain to find a workaround solution during flight planning. It also negatively affected the crew’s situational awareness during the approaches at CYSK (Sanikiluaq).
2. Weather conditions below published landing minima for the approach at the alternate airport CYGW (Kuujjuarapik) and insufficient fuel to make CYGL (La Grande Rivière) eliminated any favourable diversion options. The possibility of a successful landing at CYGW was considered unlikely and put pressure on the crew to land at CYSK (Sanikiluaq).
3. Frustration, fatigue, and an increase in workload and stress during the instrument approaches resulted in crew attentional narrowing and a shift away from welllearned, highly practised procedures.
4. Due to the lack of an instrument approach for the into-wind runway and the unsuccessful attempts at circling, the crew chose the option of landing with a tailwind, resulting in a steep, unstable approach.
5. The final descent was initiated beyond the missed approach point and, combined with the 14-knot tailwind, resulted in the aircraft remaining above the desired 3- degree descent path.
6. Neither pilot heard the ground proximity warning system warnings; both were focused on landing the aircraft to the exclusion of other indicators that warranted alternative action.
7. During the final approach, the aircraft was unstable in several parameters. This instability contributed to the aircraft being half-way down the runway with excessive speed and altitude.
8. The aircraft was not in a position to land and stop within the confines of the runway, and a go-around was initiated from a low-energy landing regime.
9. The captain possibly eased off on the control column in the climb due to the low airspeed. This, in combination with the configuration change at a critical phase of flight, as called for in the company procedures, may have contributed to the aircraft’s poor climb performance.
10. A rate of climb sufficient to ensure clearance from obstacles was not established, and the aircraft collided with terrain.
11. The infant passenger was not restrained in a child restraint system, nor was one required by regulations. The infant was ejected from the mother’s arms during the impact sequence, and contact with the interior surfaces of the aircraft contributed to the fatal injuries.
Findings as to risk:
1. If instrument approaches are conducted without reference to an approach chart, there is a risk of weakened situational awareness and of error in following required procedures, possibly resulting in the loss of obstacle clearance and an accident.
2. If additional contingency fuel is not accounted for in the aircraft weight, there is a risk that the aircraft may not be operated in accordance with its certificate of airworthiness or may not meet the certified performance criteria.
3. If Transport Canada crew resource management (CRM) training requirements do not reflect advances in CRM training, such as threat and error management and assertiveness training, there is an increased risk that crews will not effectively employ CRM to assess conditions and make appropriate decisions in critical situations.
4. If a person assisting another is seated next to an emergency exit, there is an increased risk that the use of the exit will be hindered during an evacuation.
5. If a person holding an infant is seated in a row with no seatback in front of them, there is an increased risk of injury to the infant as no recommended brace position is available.
6. If young children are not adequately restrained, there is a risk that injuries sustained will be more severe.
7. If a lap-held infant is ejected from its guardian’s arms, there is an increased risk the infant may be injured, or cause injury or death to other occupants.
8. If more complete data on the number of infants and children travelling by air are not available, there is a risk that their exposure to injury or death in the event of turbulence or a survivable accident will not be adequately assessed and mitigated.
9. If temperature corrections are not applied to all altitudes on the approach chart, there is an increased risk of controlled flight into terrain due to a reduction of obstacle clearance.
10. If the missed approach point on non-precision instrument approaches is located beyond the 3-degree descent path, there is an increased risk that a landing attempt will result in a steep, unstable descent, and possible approach-and-landing accident.
11. If there is not sufficient guidance in the standard operating procedures, there is a risk that crews will not react and perform the required actions in the event that ground proximity warning system warnings are generated.
12. If standard operating procedures, the Airplane Flight Manual and training are not aligned with respect to low-energy go-arounds, there is a risk that crews may perform inappropriate actions at a critical phase of flight.
13. If non-compliant practices are not identified, reported, and dealt with by a company’s safety management system, there is a risk that they will not be addressed in a timely manner.
14. If Transport Canada’s oversight is dependent on the effectiveness of a company’s safety management system’s reporting of safety issues, there is a risk that important issues will be missed.
Other findings:
1. The quick response of the people on the ground reduced the exposure of passengers and crew to the elements.

Findings as to causes and contributing factors:
1. The aircraft departed Snow Lake overweight and with an accumulation of ice on the leading edges of its wings and tail from the previous flight. As a result, the aircraft had reduced take-off and climb performance and increased stall speed, and the protection afforded by its stall warning system was impaired.
2. A breakdown in the company’s operational control resulted in the flight not operating in accordance with the Canadian Aviation Regulations and the company operations manual.
3. As a result, shortly after departure, the aircraft stalled at an altitude from which recovery was not possible.
Findings as to risk:
1. If companies operate in instrument meteorological conditions for which they are not authorized, there is an increased risk that accidents may occur.
2. If Transport Canada does not provide the same degree of oversight for repetitive charter operations as it does for a scheduled operator, the risks in the operator’s activities may not be fully evaluated.
3. If passenger briefings are not provided and passengers are not properly seated and restrained, there is an increased risk of injuries to those passengers and the other occupants in the event of an accident.
4. If flights are conducted without ensuring an ice-free airframe, there is a risk of decreased aircraft performance and of loss of control and collision with terrain.
Other findings:
1. On impact, the aircraft’s seats and cabin deformed as designed, and this deformation partially attenuated the impact forces.

It was determined that the pilot continued the descent under VFR mode in IMC conditions, resulting in a controlled flight into terrain.

Findings as to Causes and Contributing Factors:
1. The pilot lost control of the aircraft for undetermined reasons and the aircraft collided with terrain.
Findings as to Risk:
1. Operating an aircraft above 13 000 feet asl without an available emergency oxygen supply increases the risk of incapacitation due to hypoxia following depressurization.
Other Findings:
1. The avionics system had the capability to record data essential to the accident investigation but the recording medium was destroyed in the accident.
