Note: Following maintenance 29-Apr-2012, returned Victoria, BC - Sitka, AK.

Incident: En route. 27-Oct-2012. The operator was conducting survey operations which require the aircraft to be flown at a specific speed and altitude. The pilot was in the process of slowing down the aircraft by lowering the flaps and maintaining the proper altitude and air speed to perform the survey. Subsequently, the pilot noticed the nose of the aircraft was heavy after he had positioned the flaps about 10 degrees to maintain the correct air speed. The pilot began to make a visual sweep of the aircraft instruments and noticed the flap indicator indicated 10 degrees; however, the hydraulic pump pressure gauge was reading zero. The pilot initiated emergency procedures and deactivated the appropriate circuit breaker and used the hydraulic hand pump to lower the flaps and landed at Wainwright, Alaska without further incident. The Pilot in right seat (a&p) contacted his director of maintenance for instructions. They trouble shot the system according to the manufacturer's procedures and could not duplicate the failure. The Pilot in Control entered the appropriate discrepancy into the flight log and the appropriate corrective action, and the aircraft was returned to service.

Flew Fairbanks, AK - Deadhorse, AK., on 26-Oct-2015 Then Deadhorse-Alpine, AK. 30-Oct-2015 Ugnu-Kuparuk, AK -Fairbanks, AK - Homer, AK.

Incident: 225 km (140.6 mls) N of Deadhorse, AK. 20-Mar-2018. On March 20, 2018, about 1945 Alaska daylight time, the wheel-equipped, struck a pedestrian after take-off from a remote sea ice airstrip, about 140 miles north of Deadhorse, Alaska. The pedestrian sustained serious injuries, and the airplane sustained substantial damage. The captain, first officer, and the three passengers on board the airplane were not injured. The flight was operated by Bald Mountain Air Service, Inc., Homer, Alaska, as a 14 Code of Federal Regulations (CFR) Part 135 visual flight rules (VFR) on-demand commercial flight when the accident occurred. Visual meteorological conditions prevailed at the airplane's point of departure, and a VFR flight plan was on file. The flight was en route to Deadhorse at the time of the accident.

During a telephone interview with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC), on March 23, the accident airplane's captain said that the purpose of the flight was to provide ongoing logistical support of ICEX 2018, which involves, in part, U.S. Navy and U.K Royal Navy submarines operating beneath the frozen Arctic Ocean during a 5-week exercise. The captain stated that the flights used an airstrip on the sea ice that was lined on both sides with snow berms. The airstrip included one runway oriented north/south and an intersecting runway oriented east/west. He said that weather conditions at the time of the accident consisted of clear skies with ice pack haze. He noted that the sun was low on the horizon, resulting in shadows on the airstrip, and that flat light conditions made it difficult to discern topographical features.

The captain said that, after back-taxiing the airplane to the south end of the airstrip and just before beginning the take-off roll to the north, both pilots saw the pedestrian standing near the departure end of the airstrip on the left side and near the intersection of the east/west runway. He said that during the take-off roll, the airplane veered slightly to the left of centreline, so he applied differential engine power to correct the veer, and the airplane returned to the centreline. As the take-off roll continued, the airplane subsequently became airborne, so he lowered the nose to remain within ground effect and gain airspeed before initiating a climb. He said that as the airspeed increased, he started to climb the airplane, then initiated a left turn. During the turn, both pilots said they heard a loud thump, which was immediately followed by an aileron control anomaly. The captain reported that he continued the left turn and subsequently entered a left downwind traffic pattern for an emergency landing to the north. The captain said that after landing, both pilots saw the pedestrian lying near a snow berm on the left side of the airstrip.

A post-accident examination of the airplane revealed substantial damage to the left wing and left aileron. The pedestrian sustained a serious head and neck injuries because of the collision, and he was subsequently medevacked to Anchorage, AK for treatment.

During a hospital room interview with the NTSB IIC, on March 25, the injured pedestrian, who was an employee of the Arctic Submarine Laboratory, reported that just before the two pilots boarded the airplane, it was agreed that he would position himself alongside the airstrip to get a photo of the airplane's departure. The pedestrian noted that, as the accident airplane approached, he positioned himself behind a 3- to 4-ft tall snow berm, which was clear of the airstrip. He said that, as the airplane's take-off progressed, it did not climb as quickly as it had during previous departures. The pedestrian said that the last thing he remembered before the collision was seeing the airplane's left wing getting lower to the ground as the airplane continued to accelerate toward him. The next thing he remembered was waking up in the medevac helicopter.

Note: The aircraft (minus wings) was acquired by Gravitas Aviation Ltd, West Vancouver, BC from the ice near Deadhorse, AK As it was unflyable, and located on deteriorating sea ice, the choices became a)abandon the aircraft where it sat, or b) devise a plan to have it slung out from the very remote location. Over the ensuing days the engines and wings were able to be removed, and it was eventually recovered successfully from the ice by Tanalian & Northern Pioneer Helicopters. As the aircraft total time is less than 30,000 hrs, the aircraft will be fully repaired and overhauled.
