A Swearingen SA227-AC Metro III passenger plane was involved in an accident at Sanikiluaq Airport, NU (YSK), Canada. The flight crew sustained serious injuries, 6 passengers sustained minor injuries and one passenger, an infant, was fatally injured.
The route from Winnipeg to Sanikiluaq is normally operated by Keewatin Air, a Perimeter Aviation sister company. The normally scheduled flight on the previous day (Friday, 21 December 2012) had been cancelled due to poor weather in Sanikiluaq. With extra cargo and passengers needing to travel to Sanikiluaq before Christmas, Keewatin Air completed a flight on the morning of 22 December 2012 and had chartered Perimeter to complete an additional flight. The Perimeter flight crew had been notified in the early evening of 21 December 2012 that they would be operating flight PAG993 the next morning.

Following an attempted visual approach to runway 09, a non-precision non-directional beacon (NDB) runway 27 approach was conducted. Visual contact with the runway environment was made and a circling for runway 09 initiated. Visual contact with the runway 09 environment was lost and a return to the Sanikiluaq NDB was executed. A second NDB runway 27 approach was conducted with the intent to land on runway 27. Visual contact with the runway environment was made after passing the missed approach point. Following a steep descent, a rejected landing was initiated at 20 to 50 feet above the runway; the aircraft struck the ground approximately 525 feet beyond the departure end of runway 27.

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 work-around 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 well-learned, 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.
