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 and two passenger sustained minor injuries, two passengers sustained fatal injuries and two passengers sustained serious 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 trail of five airplanes on a scenic tour of the Lake Powell area. Shortly after making a turn back towards the airport, the accident pilot made a distress call and reported an engine issue. Subsequently, the airplane ditched in the lake near Gregory Butte and then submerged in the water. The National Park Service was able to locate the airplane using sonar equipment. The accident site was located about 13 miles northeast of the Page Municipal Airport, (PGA), Page, Arizona. Afterwards, an underwater remotely operated vehicle survey of the site took place, which revealed that the airplane came to rest upright at the lake bottom at a depth of approximately 100 ft. All major structural components of the airplane were accounted for during the survey.

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 crew departed Norfolk-Chambers Field NAS on a local mission. En route, the airplane crashed in unknown circumstances in the Chincoteague Bay, off Wallops Island. The aircraft came to rest partially submerged in shallow waters. Two crew members were rescued while the pilot Lt Hyrum Hanlon was 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 Moroni Airport at 1155LT on a schedule flight to Mohéli, carrying 12 passengers and two pilots. While approaching Mohéli, the crew encountered marginal weather conditions when the aircraft crashed in the sea some 2,5 km northwest of Mohéli-Bander es Eslam Airport. After 24 hours of intense research, only few debris were found floating on water (such a wheel and wing fragments). No trace of the 14 occupants was found.

Before departing on the flight, the pilot of the turbo-propeller-equipped, single-engine airplane and student pilot-rated passenger seated in the right front seat of the airplane attempted to enter a flight plan into the airplane’s integrated flight management system. They ultimately did not complete this task prior to takeoff with the pilot remarking, “we’ll get to it later.” The pilot subsequently departed and climbed into instrument meteorological conditions (IMC) without an instrument flight rules (IFR) flight plan. After entering IMC, he contacted air traffic control and asked for visual flight rules (VFR) flight following services and an IFR clearance to the destination airport. From shortly after when the airplane leveled after takeoff through the final seconds of the flight, the pilot attempted to program, delete, reprogram, and activate a flight plan into the airplane’s flight management system as evidenced by his comments recorded on the airplane’s cockpit voice recorder (CVR). After departing, the pilot also attempted to navigate around restricted airspace that the airplane had flown into. The CVR audio showed that during the final 10 minutes of the flight, the pilot was unsure of the spelling of the fix he should have been navigating to in order to begin the instrument approach at the destination airport, and more generally expressed frustration and confusion while attempting to program the integrated flight management system. As the pilot continued to fixate on programming the airplane’s flight management system and change the altimeter setting, the airplane’s pitch attitude increased to 10° nose up, while the airspeed had decayed to 109 knots. As a result of his inattention to this airspeed decay, the stall warning system activated and the autopilot disconnected. During this time the airplane began climbing and turning to the right and then to the left before entering a steep descending right turn that continued until the airplane impacted the ocean. For the final 2 and 1/2 minutes of the flight, the pilot was provided with stall warnings, stick shaker activations, autopilot disconnect warnings, and terrain avoidance warning system alerts. The airplane impacted the ocean about 3 miles from the coast. Examination of the recovered sections of the airplane did not reveal evidence of any mechanical failures or malfunctions of the airframe or engine that would have precluded normal operation. The instrument meteorological conditions present in the area at the time of the accident were conducive to the development of spatial disorientation. The airplane’s erratic flight track in the final 2 minutes of flight, culminating in the final rapidly descending right turn, were consistent with the known effects of spatial disorientation. It is likely that the pilot’s inadequate preflight planning, and his subsequent distraction while he unsuccessfully attempted to program the airplane’s flight management system during the flight resulted in his failure to adequately monitor the airplane’s speed. This led to the activation of the airplane’s stall protection and warning systems as the airplane approached and entered an aerodynamic stall. The resulting sudden deactivation of the autopilot, combined with his inattention to the airplane’s flight attitude and speed, likely surprised the pilot. Ultimately, the pilot failed to regain control of the airplane following the aerodynamic stall, likely due to spatial disorientation. The pilot had a history of mantle cell lymphoma that was in remission and his maintenance treatment with a rituximab infusion was over 60 days prior to the accident. The pilot also had a history of back pain and had received steroid injections and nonsteroidal anti-inflammatory drugs. By self-report, he had taken oxycodone for pain management; it is unknown how frequently he used this medication or if he had used the medication on the day of the accident. While oxycodone can result in fatigue and dizziness, and may interfere with reaction time, given the information from the CVR, it could not be determined if the pilot had these side effects. A few weeks prior to the accident, the pilot reported having COVID-19 and receiving a 5-day treatment course of hydroxychloroquine and ivermectin. While there are some impairing side effects associated with the use of those medications, enough time had elapsed that no adverse effects would be expected. There is an increased risk of a sudden incapacitating cardiovascular event such as a dysrhythmia, stroke, or pulmonary embolism in people who have recovered from their COVID-19 infection. The risk is slight for those not hospitalized for the infection. The pilot did not have an underlying cardiovascular disease that would pose an increased risk for a sudden incapacitating event and the CVR did not provide evidence of a sudden incapacitating event occurring. Thus, it could not be determined if the pilot’s medical conditions of mantle cell lymphoma, back pain, and recent history of COVID-19 and the medications used to treat these conditions, including rituximab, oxycodone, hydroxychloroquine, and ivermectin, were contributing factors to this accident.

The aircraft departed the Opa Locka Executive Airport (KOPF), Opa Locka, Florida, USA at 7:52 AM EST (1252 UTC) with 2 persons on board enroute to the Chub Cay Int’l Airport. The aircraft was operated by Airway Air Charter INC (Venture Air Solutions INC), a Part 135 certificate holder under Title 14 US Code of Federal Regulations (CFR), Investigations revealed that the pilot in command arrived at the Opa Locka Airport at approximately 6:30 AM EST and conducted a pre-flight check of the aircraft, subsequently adding 66.5 gallons of 100LL avgas fuel to the main fuel tanks of the aircraft. No fuel was added to the auxiliary tanks. After completion of all pre-flight checks, and gaining clearance from Air Traffic Control, the aircraft departed at approximately 7:52 AM EST. Investigations revealed that the flight was uneventful, until descending into Chub Cay, at about 2,500 feet, when the left engine began to “sputter”. At this point the pilot executed the engine failure checklist, but shortly thereafter, the right engine began to “sputter” also. The pilot then contacted Miami air traffic center and advised of loss of power to both engines, which resulted in the aircraft crashing into waters. The United States Coast Guard along with the Royal Bahamas Defense Force (RBDF) and Police Force (RBPF) were alerted. Joint aerial and marine assets were dispatched and additional assistance was provided by local mariners and pilots flying in the area to conduct search and rescue. Both occupants were located and rescued. They were later airlifted to the United States to receive further medical attention for minor injuries. Image from Google Earth of accident site and distance from Chub Cay Airport The location where the aircraft crashed was identified at coordinates 25° 24.884’ N and 077° 58.030’ W, approximately 4.48 NM west of the Chub Cay International Airport (MYBC), Berry Islands, Bahamas.

Shortly after departure, the engine lost total power and the pilot was forced to ditch in open water; the occupants egressed and were subsequently rescued by a recreational vessel. Examination of the engine revealed a fracture hole near the n°2 cylinder, which was likely the result of the n°2 cylinder connecting rod fracturing in fatigue as a result of high heat and high stress associated with failure of the n°2 bearing. The fatigue fracture displayed multiple origins consistent with relatively high cyclic stress, which likely occurred as excessive clearances developed between the bearing and the crankshaft journal. The n°2 connecting rod bearing may have failed due to a material defect in the bearing itself or due to a disruption in the oil lubrication supply to the bearing/journal interface. Either situation can cause similar damage patterns to develop, including excessive heating and subsequent bearing failure.

The twin engine aircraft departed Waterford Airport for a local survey flight. While flying at low altitude, the pilot reported technical difficulties and attempted an emergency landing when the aircraft crashed on a beach located in Carnsore Point and came to rest partially submerged in water. All four occupants were taken to hospital and the aircraft was destroyed.

The single engine airplane departed Borkum Airport in the early afternoon on a local skydiving mission. At an altitude of 14,000 feet, the skydivers jumped out the cabin then the pilot reduced his altitude and returned to Norderney Airport. On approach, control was lost and the airplane crashed in the sea of Wadden, about 4 km southeast of the airfield. The aircraft was destroyed and the pilot was killed.
