Charter/Taxi (Non Scheduled Revenue Flight)

On September 4, 2022, about 1509 Pacific daylight time, a float-equipped de Havilland DHC-3 (Otter), N725TH, was destroyed when it impacted the water in Mutiny Bay, near Freeland, Washington, and sank. The pilot and nine passengers were fatally injured. The airplane was owned by Northwest Seaplanes, Inc., and operated as a Title 14 Code of Federal Regulations (CFR) Part 135 scheduled passenger flight by West Isle Air dba Friday Harbor Seaplanes. The flight originated at Friday Harbor Seaplane Base (W33), Friday Harbor, Washington, with an intended destination of Will Rogers Wiley Post Memorial Seaplane Base (W36), Renton, Washington. Visual meteorological conditions prevailed at the time of the accident. The accident pilot was scheduled to fly the accident airplane on three multiple leg roundtrips on the day of the accident. The first roundtrip flight was uneventful; it departed from W36 about 0930, made four stops, and returned about 1215. The accident occurred during the pilot’s second trip of the day. A review of recorded automatic dependent surveillance–broadcast (ADS-B) data revealed that the second roundtrip departed 36 about 1253 and arrived at Lopez Seaplane Base, (W81), Lopez Island, Washington, about 1328.2 The data showed that the flight then departed W81 and landed at Roche Harbor Seaplane Base (W39) about 1356. The airplane departed W39 about 1432, arrived at W33 about 1438, and departed about 1450. According to ADS-B data, after the airplane departed W33, it flew a southerly heading before turning south-southeast. The en route altitude was between 600 and 1,000 ft above mean sea level (msl), and the groundspeed was between 115 and 135 knots. At 1508:40, the altitude was 1,000 ft msl, and the groundspeed had decreased to 111 knots. Based on performance calculations, at 1508:43, the airplane pitched up about 8° and then abruptly pitched down about 58°. The data ended at 1508:51, when the airplane’s altitude was 600 ft msl and the estimated descent rate was more than 9,500 ft per minute (the flightpath of the airplane is depicted in figure. Witnesses near the accident site reported, and security camera video confirmed, the airplane was in level flight before it entered a slight climb and then pitched down. One witness described the descent as “near vertical” and estimated the airplane was in an 85° nose-down attitude before impact with the water. Several witnesses described the airplane as “spinning,” “rotating,” or “spiraling” during portions of the steep descent. One witness reported hearing the engine/propeller and noted that he did not hear any “pitch change” in the sounds. The airplane continued in a nose-low, near-vertical descent until it impacted water in Mutiny Bay.

On August 13, 2022, about 1619 mountain standard time, a Cessna T207A airplane, N9582M, was substantially damaged when it was involved in an accident near Page, Arizona. The pilot received minor injuries, two passengers were fatally injured, two passengers were seriously injured, and one passenger received minor injuries. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 air tour flight. According to witnesses, the accident airplane was the first airplane in a flight of 5 airplanes on a scenic tour of the Lake Powell area at a cruise altitude of about 1,000 ft to 2,000 ft above ground level. After nearly 30 minutes of flight and after making a turn back towards the airport, the accident pilot made a distress call and reported his engine lost power and he was ditching the airplane in Lake Powell. The airplane became submerged in the water and the two passengers who were fatally injured did not exit the airplane. National Park Service boats, several nearby private boats, and a few helicopters responded to the accident site, which was located about 13 miles northeast of the Page Municipal Airport, (PGA), Page, Arizona. The boats assisted the survivors in the water. Once aboard a boat that recovered the survivors, witnesses overheard the pilot on the phone discussing that he had experienced an engine failure. An underwater remote observation vehicle surveyed the accident site a couple of days after the accident. All major components of the airplane were observed, and the airplane came to rest upright at the lake bottom about 100 ft below the surface.

The pilot reported that, he was departing in the float-equipped airplane in strong gusty wind conditions. After accelerating on the water for about 3 seconds, the airplane suddenly became airborne and crabbed into the wind about 60° to 90° from the intended takeoff path and started to climb as it continued to track away from the intended flight path. As the climb continued, the airplane stalled and impacted the water in a nose low attitude which resulted in substantial damage to the wings and fuselage. The pilot reported that there were no preaccident mechanical malfunctions or anomalies that would have precluded normal operation.

The purpose of the flight was to transport three passengers and cargo. The pilot reported that, during takeoff, the airplane’s tail came up slightly lowered to the runway when he attempted to raise the tail by applying forward elevator. He stated that he thought this was unusual and attributed it to an aft-loaded airplane. He applied additional nose-down trim and departed without incident. While en route, the tail of the airplane seemed to move up and down, which the pilot attributed to turbulence. Upon arrival at his destination, the pilot entered a left downwind, reduced the power and extended the flaps to 10° abeam the end of the runway. He turned onto the base leg about ½ mile from the approach end of the runway and slowed the airplane to 80 mph. Turning final, he noticed the airplane seemed to pitch up, so he applied full nose-down pitch trim and extended the flaps an additional 10°. On short final he applied full flaps, and the airplane abruptly pitched up to about a 45° angle. He stated that he applied full nose-down elevator, verified the pitch trim, and reduced the power to idle. When the airplane was about 300 ft above ground level, the airplane stalled, the left wing dropped slightly, and the airplane entered about a 45° nose-down dive. After allowing the airplane to gain airspeed, the pilot applied full back elevator. The airplane impacted forested terrain near the approach end of runway 23 at an elevation of about 18 ft. A postaccident examination of the airframe and engine revealed no evidence of preaccident mechanical malfunctions or failures that would have precluded normal operation. Elevator and rudder control continuity was confirmed from the cockpit to the respective control surfaces. The airplane's estimated gross weight at the time of the accident was about 7,796 lbs and the airplane's estimated center of gravity was about 3.2 to 5.6 inches beyond the approved aft limit. Maximum gross weight for the airplane is 8,000 lbs.

The twin engine airplane departed Yaoundé at 1246LT on a charter flight to Dompta and Belabo, carrying 9 employees of the Cameroon Oil Transportation Company (COTCO) and two crew members. En route, the airplane crashed in unknown circumstances near the village of Nanga Eboko. All 11 occupants were killed.

On 08 March 2022, the Bamaji Air Inc. (Bamaji) wheel-equipped Cessna 208 Caravan aircraft (registration C-GIPR, serial number 20800343) was conducting a series of visual flight rules (VFR) flights from Sioux Lookout Airport (CYXL), Ontario. At 1031, after checking the aerodrome forecast (TAF) valid from 0900 to 2000, and the graphic area forecast (GFA) valid from 0600 to 1800, the pilot departed on a flight to an ice runway on Springpole Lake, Ontario, about 78 nautical miles (NM) north-northwest of CYXL. The aircraft returned to CYXL with 2 passengers at 1200. In preparation for a second flight to Springpole Lake, the pilot loaded approximately 900 pounds of freight into the cabin and secured it under a cargo net. The aircraft had 750 pounds of fuel remaining on board, which was sufficient for the planned flight. The pilot and 1 passenger boarded the aircraft. The pilot occupied the left cockpit seat and the passenger occupied the right cockpit seat. Both occupants were wearing the available 5-point-harness safety belt system. At 1250, a snow squall began to move across CYXL, reducing ground visibility. The pilot taxied the aircraft to a position on the apron and waited for the fast-moving snow squall to pass. At 1301, the pilot taxied the aircraft to Runway 34 and took off in visual meteorological conditions. The aircraft climbed to approximately 1800 feet above sea level (ASL), then, once clear of the control zone, it descended to approximately 1600 to 1700 feet ASL, roughly 500 to 600 feet above ground level (AGL), to remain below the overcast ceiling. As the aircraft began to cross Lac Seul, Ontario, the visibility straight ahead and to the west was good. However, when the aircraft was roughly midway across the lake, it encountered turbulence and immediately became enveloped in whiteout conditions generated by a snow squall. The pilot turned his head to inspect the left wing and saw that ice appeared to be accumulating on the leading edge. He turned his attention back to the flight instruments and saw that the altimeter was descending rapidly. He then pulled back on the control column to stop the descent; however, within a few seconds, the aircraft struck the frozen surface of Lac Seul, approximately 17 NM north-northwest of CYXL. The aircraft was substantially damaged. There was no fire. The aircraft occupants received minor injuries. The Artex Model Me406 emergency locator transmitter (ELT) activated on impact and the signal was detected by the Cospas-Sarsat satellite system. The Joint Rescue Coordination Centre in Trenton, Ontario, re-tasked a Royal Canadian Air Force aircraft that was in the area and 3 search and rescue technicians (SAR Techs) parachuted into the site within 1 hour of the accident. The aircraft occupants and the SAR Techs were extracted from the site by a civilian helicopter later that day.

The single engine airplane departed Nazca-María Reiche Neuman Airport on a local sightseeing flight, carrying five passengers and two crew members. During the rotation phase, the aircraft presented mechanical failures evidenced by unusual noises and a progressive decrease in engine power. The crew continued the takeoff without reaching the necessary speed and altitude for a safe climb. The pilot reported he was returning to the airport when the aircraft entered into a loss of aerodynamic lift, violently impacting the ground. The strong impact caused multiple serious injuries to the occupants and triggered a fire that destroyed a large part of the aircraft. All seven occupants were killed.

Following an uneventful flight from RCAF Trenton on behalf of the RCAF, the twin engine aircraft apparently landed hard at Thunder Bay Airport. After touchdown on runway 25, it went out of control and veered off runway into a snow covered area. All three crew members evacuated safely while the aircraft suffered severe damages to wings and tail. The fuselage also broke in two.

The airplane was on a VFR charter flight from Kiunga Airport, Western Province to Tekin Airstrip, Sandaun Province, Papua New Guinea. During the landing roll aircraft sustained a left main landing gear assembly collapse and subsequent runway excursion. There were seven persons onboard: one pilot and six passengers. At 09:06, P2-BWC departed Kiunga Airport and arrived at Tekin circuit area at 09:40. The pilot established the aircraft on the final approach profile, he configured the aircraft for landing by fully extending the flaps and maintained an airspeed of about 80 knots (kts). The pilot also stated that he experienced a downdraft prior to touch down. The aircraft landed at 09:43 with an airspeed of 75 knots as recalled by the pilot. The aircraft touched down about 3m short of the airstrip edge boundary. The investigation determined that due to reduced damping effect of the oleo and/or the tyre of the left main landing gear, the landing gear attachment bolts sustained significant impact stress from the landing impact force and snapped, causing the gear assembly to collapse and separate from the aircraft. Subsequently, the left wing abruptly dropped, and the aircraft began veering to the left, towards the eastern edge of the airstrip. The aircraft continued veering to the left and subsequently the left wingtip struck the outer edge of the extended right-hand flap of P2-BWE, a wreckage of the same aircraft type owned and operated by NASL that was involved in a similar accident on 18 January 2022, causing P2-BWC to abruptly veer further left and skid across the airstrip boundary as the nose-wheel and right main wheel bogged into the ground. The pilot immediately shut down the engine and evacuated the passengers with the assistance of one of the Operator’s personnel who was also a passenger on board. There were no reported injuries and the aircraft sustained significant damage.

The airplane was conducting a single pilot VFR charter flight from Kiunga Airport, Western Province to Tekin Airstrip, Sandaun Province, Papua New Guinea when during the landing roll, the aircraft sustained a left Main Landing Gear (MLG) assembly collapse and subsequent runway excursion. There were eight persons onboard: one pilot and seven passengers. At 08:43, P2-BWE departed Kiunga Airport and arrived at Tekin Airstrip circuit at 09:18. The pilot then tracked towards the Northwest of the airstrip and made a left base turn for approach. The pilot stated that he established the aircraft on final approach with an airspeed of 120 kts. He subsequently configured the aircraft for landing; propeller pitch set to full fine, power set to maintain nominated approach speed, and full flap. The pilot indicated that he reduced airspeed while on approach and maintained an airspeed between 85 and 90 kts. As he flared the aircraft to land, the airspeed was between 75 to 80 kts. The touchdown speed, as he recalled, was 75 kts. The aircraft touched down two metres short of the designated landing threshold of runway18, which had an elevation of 15cm. Reviewing the flight records of the pilot, and from his interview, the AIC deduced that the pilot was not adequately familiar with Tekin Airstrip. The aircraft sustained substantial damaged. All the passengers and pilot evacuated the aircraft without injuries.
