Charter/Taxi (Non Scheduled Revenue Flight)

The twin engine aircraft departed Bogotá-El Dorado on a short flight to Bogotá-Guaymaral Airport, carrying three passengers and one pilot. Three minutes after takeoff from runway 13L, while climbing to a height of 200 feet in VFR conditions, the airplane entered a left turn then descended into the ground and crashed into several houses located in the district of Engativá, near the airport, bursting into flames. The aircraft as well as several houses and vehicles were destroyed. All four occupants as well as five people on the ground were killed. Thirteen others were injured, seven seriously.

The twin engine aircraft, operated by STS Avijacija (STS Aviation), departed Banja Luka on a charter flight to Tuzla, carrying two passengers and one pilot taking part to a foxes vaccination program. While cruising at low altitude, the airplane entered an area of clouds when it impacted trees and crashed on the slope of a mountain located near the Monastery of Ozren, southeast part of the Serbian Republic of Bosnia, bursting into flames. Both passengers were seriously injured and the pilot was killed.

On September 15, 2015, about 0606 Alaska daylight time, a single-engine, turbine-powered, float-equipped de Havilland DHC-3T (Otter) airplane, N928RK, impacted tundra-covered terrain just after takeoff from East Wind Lake, about 1 mile east of the Iliamna Airport, Iliamna, Alaska. Of the 10 people on board, three passengers died at the scene, the airline transport pilot and four passengers sustained serious injuries, and two passengers sustained minor injuries. The airplane sustained substantial damage. The airplane was registered to and operated by Rainbow King Lodge, Inc., Lemoore, California, as a visual flight rules other work use flight under the provisions of 14 Code of Federal Regulations (CFR) Part 91. Dark night, visual meteorological conditions existed at the departure point at the time of the accident, and no flight plan was filed for the flight. At the time of the accident, the airplane was en route to a remote fishing site on the Swishak River, about 75 miles northwest of Kodiak, Alaska.

Following an uneventful flight from Salzburg, the crew was cleared to descent to Vienna-Schwechat Airport. On approach to runway 34, the crew completed the checklist and lowered the landing gear when he realized the the left main gear remained stuck in its wheel well and that the green light failed to come on on the cockpit panel. The crew agreed to continue. After touchdown on runway 34, the aircraft deviated to the left, veered off runway and came to rest in a grassy area located near taxiway D and taxiway B5 and B6. All five occupants evacuated safely and the aircraft was damaged beyond repair.

The crew was performing a charter flight from Oranjestad (Aruba) to Charallave with an intermediate stop in Barcelona. While on a night approach to runway 10, the captain initiated a go-around procedure for unknown reasons. During the second attempt to land, the aircraft landed long and the touchdown point appeared to be half way down the runway 10 which is 2,000 meters long. Unable to stop within the remaining distance, the aircraft overran, went down an embankment and came to rest. All eight occupants evacuated safely while the aircraft was damaged beyond repair. The passengers were members of the pop band 'Los Cadillac's' accompanied by the Venezuelan singer and actor Arán de las Casas.

The float-equipped de Havilland DHC-2 Mk. 1 Beaver (registration C-FKRJ, serial number 1210), operated by Air Saguenay (1980) inc., was on a visual flight rules sightseeing flight in the region of Tadoussac, Quebec. At 1104 Eastern Daylight Time, the aircraft took off from its base on Lac Long, Quebec, for a 20-minute flight, with 1 pilot and 5 passengers on board. At 1127, on the return trip, approximately 2.5 nautical miles north-northwest of its destination (7 nautical miles north of Tadoussac), the aircraft stalled in a steep turn. The aircraft descended vertically and struck a rocky outcrop. The aircraft was substantially damaged in the collision with the terrain and was destroyed by the post-impact fire. The 6 occupants received fatal injuries. No emergency locator transmitter signal was captured.

On 16 August 2015, a Maritime Air Charter Limited Beechcraft King Air A100 (registration C-FDOR, serial number B-103) was on a charter flight from Halifax Stanfield International Airport, Nova Scotia, to Margaree Aerodrome, Nova Scotia, with 2 pilots and 2 passengers on board. At approximately 1616 Atlantic Daylight Time, while conducting a visual approach to Runway 01, the aircraft touched down hard about 263 feet beyond the threshold. Almost immediately, the right main landing gear collapsed, then the right propeller and wing contacted the runway. The aircraft slid along the runway for about 1350 feet, then veered right and departed off the side of the runway. It came to rest about 1850 feet beyond the threshold and 22 feet from the runway edge. There were no injuries and there was no post-impact fire. The aircraft was substantially damaged. The occurrence took place during daylight hours. The 406-megahertz emergency locator transmitter did not activate.

On 12 August 2015, a PAC-750XL aircraft, registered PK-KIG, was being operated by PT. Komala Indonesia on an unscheduled passenger flight from Wamena Airport (WAJW) Papua to Ninia Airstrip , Yahukimo, Papua that was located on radial 127° from Wamena with a distance of approximately 26 Nm. At 0733 LT (2233 UTC), the aircraft departed from Wamena Airport with an estimated time of arrival at Ninia of 2248 UTC. The flight was uneventful until approaching Ninia. On board the aircraft were one pilot, one engineer and 4 passengers. According to the pilot statement, an airspeed indicator malfunction occurred during flight. Video footage taken by a passenger showed that, during the approach at an altitude of approximately 6,500 feet, the airspeed indicators indicated zero and the aural stall warning activated. The aircraft then flew on the left side and parallel to the runway. Thereafter the aircraft climbed, turned left and impacted the ground about 200 meters south-west of the runway. The engineer on board was fatally injured, one passenger had minor injuries and the other occupants, including the pilot, were seriously injured. Two occupants were evacuated to a hospital in Jayapura Airport and four others, including the fatally injured, were evacuated to a hospital in Wamena.

The airplane collided with mountainous, tree-covered terrain about 24 miles east-northeast of Ketchikan, Alaska. The commercial pilot and eight passengers sustained fatal injuries, and the airplane was destroyed. The airplane was owned by Pantechnicon Aviation, of Minden, Nevada, and operated by Promech Air, Inc., of Ketchikan. The flight was conducted under the provisions of 14 Code of Federal Regulations (CFR) Part 135 as an on-demand sightseeing flight; a company visual flight rules flight plan (by which the company performed its own flight-following) was in effect. Marginal visual flight rules conditions were reported in the area at the time of the accident. The flight departed about 1207 from Rudyerd Bay about 44 miles east-northeast of Ketchikan and was en route to the operator’s base at the Ketchikan Harbor Seaplane Base, Ketchikan. The accident airplane was the third of four Promech-operated float-equipped airplanes that departed at approximate 5-minute intervals from a floating dock in Rudyerd Bay. The accident flight and the two Promech flights that departed before it were carrying cruise-ship passengers who had a 1230 “all aboard” time for their cruise ship that was scheduled to depart at 1300. (The fourth flight had no passengers but was repositioning to Ketchikan for a tour scheduled at 1230; the accident pilot also had his next tour scheduled for 1230.) The sightseeing tour flight, which the cruise ship passengers had purchased from the cruise line as a shore excursion, overflew remote inland fjords; coastal waterways; and mountainous, tree-covered terrain in the Misty Fjords National Monument Wilderness. Promech pilots could choose between two standard tour routes between Rudyerd Bay and Ketchikan, referred to as the “short route” (which is about 52 nautical miles [nm], takes about 25 minutes to complete, and is primarily over land) and the “long route” (which is about 63 nm, takes about 30 minutes to complete, and is primarily over seawater channels). Although the long route was less scenic, it was generally preferred in poor weather conditions because it was primarily over water, which enabled the pilots to fly at lower altitudes (beneath cloud layers) and perform an emergency or precautionary landing, if needed. Route choice was at each pilot’s discretion based on the pilot’s assessment of the weather. The accident pilot and two other Promech pilots (one of whom was repositioning an empty airplane) chose the short route for the return leg, while the pilot of the second Promech flight to depart chose the long route. Information obtained from weather observation sources, weather cameras, and photographs and videos recovered from the portable electronic devices (PEDs) of passengers on board the accident flight and other tour flights in the area provided evidence that the accident flight encountered deteriorating weather conditions. Further, at the time of the accident, the terrain at the accident site was likely obscured by overcast clouds with visibility restricted in rain and mist. Although the accident pilot had climbed the airplane to an altitude that would have provided safe terrain clearance had he followed the typical short route (which required the flight to pass two nearly identical mountains before turning west), the pilot instead deviated from that route and turned the airplane west early (after it passed only the first of the two mountains). The pilot’s route deviation placed the airplane on a collision course with a 1,900-ft mountain, which it struck at an elevation of about 1,600 ft mean sea level. In the final 2 seconds of the flight, the airplane pitched up rapidly before colliding with terrain. The timing of this aggressive pitch-up maneuver strongly supports the scenario that the pilot continued the flight into near-zero visibility conditions, and, as soon as he realized that the flight was on a collision course with the terrain, he pulled aggressively on the elevator flight controls in an ineffective attempt to avoid the terrain. Although Promech’s General Operations Manual specified that both the pilot and the flight scheduler must jointly agree that a flight can be conducted safely before it is launched, no such explicit concurrence occurred between the accident pilot and the flight scheduler (or any member of company management) before the accident flight. As a result, the decision to initiate the accident tour rested solely with the accident pilot, who had less than 2 months’ experience flying air tours in Southeast Alaska and had demonstrated difficulty calibrating his own risk tolerance for conducting tour flights in weather that was marginal or below Federal Aviation Administration (FAA) minimums. Further, evidence from the accident tour flight and the pilot’s previous tour flights support that the pilot’s decisions regarding his tour flights were influenced by schedule pressure; his attempt to emulate the behavior of other, more experienced pilots whose flights he was following; and Promech’s organizational culture, which tacitly endorsed flying in hazardous weather conditions, as evidenced (in part) by the company president/chief executive officer’s own tour flight below FAA minimums on the day of the accident.

The twin engine airplane departed Miranda-Estância Caimam Airfield at 0915LT on a charter flight to Campo Grande, carrying seven passengers and two pilots. About 35 minutes into the flight, while flying 79 km from the destination in good weather conditions, the left engine failed. The crew was unable to feather the propeller and to maintain a safe altitude, so he decided to attempt an emergency landing. The aircraft belly landed in an agriculture area, slid for few dozen metres and came to rest. All nine occupants suffered minor injuries and the aircraft was damaged beyond repair.
