Airport (less than 10 km from airport)

The pilot obtained a preflight weather briefing about 2.5 hours before departing on an instrument flight rules (IFR) cross-country flight. Automatic dependent surveillance-broadcast (ADS-B) and weather data indicated the flight encountered low IFR (LIFR) conditions during the approach to the destination airport. These conditions included low ceilings, low visibility, localized areas of freezing precipitation, low-level turbulence and wind shear. The ADS-B data revealed that during the last minute of data, the airplane’s descent rate increased from 500 ft per minute to 3,000 ft per minute. In the last 30 seconds of the flight the airplane entered a 2,000 ft per minute climb followed by a descent that exceeded 5,000 ft per minute. The last data point was located about 1,000 ft from the accident site. There were no witnesses to the accident. A postaccident examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation. The airplane’s flight instruments and avionics were destroyed during the accident and were unable to be functionally tested. The rapid ascents and descents near the end of the flight track were consistent with a pilot who was experiencing spatial disorientation, which resulted in a loss of control and high-speed impact with terrain. The pilot purchased the airplane about 3 weeks before the accident and received about 15 hours of transition training in the airplane, including 1 hour of actual instrument conditions during high-altitude training. The pilot’s logbook indicated he had 5.2 hours of actual instrument flight time. At the time of the pilot’s weather briefing, the destination airport was reporting marginal visual flight rules (MVFR) conditions with the terminal area forecast (TAF) in agreement, with MVFR conditions expected to prevail through the period of the accident flight. LIFR conditions were reported about 40 minutes before the airplane’s departure and continued to the time of the accident. Light freezing precipitation was reported intermittently before and after the accident, which was not included in the TAF. The destination airport’s automated surface observing system (ASOS) reported LIFR conditions with overcast ceilings at 300 ft above ground level (agl) and light freezing drizzle at the time of the accident. Low-level turbulence and wind shear were detected, which indicated a high probability of a moderate or greater turbulence layer between 3,600 and 5,500 ft mean sea level (msl) in the clouds. During the approach, the airplane was in instrument meteorological conditions with a high probability of encountering moderate and greater turbulence, with above freezing temperatures. The National Weather Service (NWS) had issued conflicting weather information during the accident time period. The pilot’s weather briefing indicated predominately MVFR conditions reported and forecasted by the TAFs along the route of flight, while both the NWS Aviation Weather Center (AWC) AIRMET (G-AIRMET) and the Graphic Forecast for Aviation (GFA) were depicting IFR conditions over the destination airport at the time of the briefing. The TAFs, GAIRMET, and Current Icing Product (CIP)/Forecast Icing Products (FIP) were not indicating any forecast for icing conditions or freezing precipitation surrounding the accident time. The pilot reviewed the TAF in his briefing, expecting MVFR conditions to prevail at his expected time of arrival. The TAF was amended twice between the period of his briefing and the time of the accident to indicate IFR to LIFR conditions with no mention of any potential freezing precipitation or low-level wind shear (LLWS) during the period. Given the pilot’s low actual instrument experience, minimal amount of flight experience in the accident airplane, and the instrument conditions encountered during the approach with a high probability of moderate or greater turbulence, it is likely that the pilot experienced spatial disorientation and lost control of the airplane.

The pilot flew a visual approach to his home airport but did a go-around due to ground fog. After receiving an instrument flight rules clearance, he flew an RNAV/GPS approach that he also discontinued due to ground fog. After executing a missed approach, the pilot flew another RNAV/GPS approach. The pilot reported that during this last approach he lost visual references and initiated a go-around, during which the airplane impacted trees about 800 ft to the right of the runway. The main wreckage came to rest upright and was consumed by a post-impact fire. The postaccident examination revealed no preimpact anomalies that would have precluded normal operation. The pilot reported that he observed the right engine was slower to accelerate than the left engine during the attempted go-around, and that he was distracted looking at the engine indications. He reported that he did not notice if the airplane yaw to the right and, before he could correct for the altitude loss, the airplane descended into and struck the trees.

The single engine airplane was engaged in a local training flight at Puerto Ayacucho Airport, carrying five pilots. While completing a turn on approach to runway 04, the airplane went out of control and crashed in a wooded area located about 3 km south of the airport, bursting into flames. The airplane was totally destroyed by impact forces and a post crash fire and all five occupants were killed. Puerto Ayacucho Airport is named Cacique Aramare but the military side is named José Antonio Páez.

The pilot reported that he was under the impression that his airplane’s inboard fuel tanks had been topped and he had 202 gallons on board prior to departure. He had a “standing order” with the airport’s fixed base operator to top the tanks; however, the fueling was not accomplished and he did not visually check the fuel level prior to departure. He entered 202 gallons in cockpit fuel computer and unknowingly commenced the flight with 61 gallons on board. Prior to reaching his destination, his fuel supply was exhausted, both engines lost all power, and he performed a forced landing in a cemetery about one mile from the airport. The pilot and his passenger had minor injuries. Inspectors with the Federal Aviation Administration examined the wreckage and determined that damage to the wings and fuselage was substantial. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

The airplane departed Seoul-Incheon Airport at 1920LT on a schedule service to Mactan, Philippines, carrying 165 passagers and a crew of 11. On approach to Mactan Airport Runway 22 at night, the crew encountered poor weather conditions with thunderstorm activity. Due to the presence of CB's at 1,800 feet, the captain decided to abort the approach and initiated a go around procedure. Fourteen minutes later, at 2226LT, on short final and after crossing the runway threshold, the airplane encountered windshear and apparently touched down hard. The crew aborted the landing procedure for a second time and initiated a second go around manoeuvre. The crew followed a holding pattern for about 30 minutes then was cleared for a third approach. After touchdown on a wet runway 22 (3,310 metres long), the airplane was unable to stop within the remaining distance and overran at a speed of 80 knots. While contacting soft ground, the nose gear was torn off then the airplane collided with various equipment of the localizer antenna and came to rest 360 metres past the runway end. All 176 occupants evacuated safely.

Shortly after departure to pick up a passenger at their destination airport about 75 nm away, the pilots climbed and turned onto a track of about 115° before leveling off about 11,000 ft mean sea level (msl), where the airplane remained for a majority of the flight. Pilot and controller communications during the flight were routine and there were no irregularities reported. As the airplane descended into the destination airport area, the airplane passed through areas of light to heavy icing where there was a 20 to 80% probability of encountering supercooled large droplets (SLD) during their initial descent and approach. While level at 4,000 ft msl, the flight remained in icing conditions, and then was cleared for the instrument approach to the runway. The flight emerged from the overcast layer as it crossed the final approach fix at 2,800 ft msl; the flight continued its descent and was cleared to land. The controller informed the flight that there was a vehicle on the runway but it would be cleared shortly, which was acknowledged; this was the final communication from the flight crew. Multiple eyewitnesses and security camera footage revealed that the airplane, while flying straight and level, suddenly began a steep, spinning, nearly vertical descent until it impacted a commercial business parking lot; the airplane subsequently collided with several unoccupied vehicles and caught fire. The airplane was certified for flight in known icing conditions and was equipped with pneumatic deice boots on each of the wings and tail surfaces. The pneumatic anti-icing system was consumed by the postimpact fire; the control switches were impact and thermally damaged and a reliable determination of their preimpact operation could not be made. Further examination of the airframe and engines revealed no indications of any preimpact mechanical anomalies that would have precluded normal engine operation or performance. During the approach it is likely that the airframe had been exposed to and had built-up ice on the control surfaces. It could not be determined if the pilots used the pneumatic anti-icing system, or if the system was inoperative, based on available evidence. Review of the weather conditions and the airplane’s calculated performance based on ADS-B data, given the speeds at which the airplane was flying, and the lack of any discernable deviations that might have been expected due to an extreme amount of ice accumulating on the airframe, it is also likely that the deice system, if operating at the time of the icing encounter, should have been able to sufficiently remove the ice from the surfaces. Although it is also uncertain when the pilots extended the landing gear and flaps, it is likely that the before-landing checklist would be conducted between the final approach fix and when the flight was on its 3-mile final approach to land. Given this information, the available evidence suggests that the sudden loss of control from a stable and established final approach was likely due to the accumulation of ice on the tailplane. It is likely that once the pilots changed the airplane’s configuration by extending the landing gear and flaps, the sudden aerodynamic shift resulted in the tailplane immediately entering an aerodynamic stall that maneuvered the airplane into an attitude from which there was no possibility to recover given the height above the ground. Postaccident toxicological testing detected the presence of delta-8 THC. Delta-8 THC has a potential to alter perception and cause impairment, but only the non-psychoactive metabolite carboxy-delta-8-THC was present in the pilot’s liver and lung tissue. Thus, it is unlikely that the pilot’s delta-8-THC use contributed to the accident.

On September 20, 2022, about 0709 Pacific daylight time, a Cessna 525B, jet airplane, N528DV, was destroyed when it was involved in an accident near Pasco, Washington. The pilot and 9 passengers were not injured. The airplane was operated as a Title 14 Code of Federal Regulations (CFR) Part 91 business flight. The pilot reported that the flight to Tri-Cities Airport, (PSC), Pasco, Washington, was uneventful; he reported to the tower controller that the airport was in sight and requested to land on runway 3L. While on left base, the pilot further reported that he started to lower the flaps and extended the gear handle. He did not recall confirming whether the gear was down and locked but reported that there were no landing caution annunciation or aural warnings. Before making contact with the runway, the pilot noticed that the airplane floated longer than expected and upon touchdown realized that the landing gear was not extended. The airplane slid down the runway and came to a stop near the departure end of the runway. The pilot secured the engines and assisted the passengers evacuate the airplane. During the evacuation, the pilot reported that the airplane was on fire near the right engine. Shortly thereafter, the airplane was engulfed in flames.

During the takeoff roll from runway 31 at El Estrecho Airport, the crew encountered an unexpected situation and rejected takeoff. Unable to stop within the remaining distance, the aircraft overran, crossed a road and crashed against a wooded embankment. The right wing was partially sheared off and the undercarriage were torn off. All 17 occupants were injured, five seriously. One passenger died from injuries sustained.

After takeoff from runway 35 at Saltillo-Plan de Guadalupe Airport, while climbing to an altitude of 800 feet, the crew encountered technical issues with the right engine that lost power and started to vibrate. The crew reduced his altitude and attempted an emergency landing when the aircraft crashed in bushes about 4,5 km northwest of the airport and came to rest. Both pilots were uninjured and the aircraft was damaged beyond repair.

After takeoff from Porto Trombetas Airport, the pilot encountered engine problems and attempted an emergency landing. The airplane crashed in a wooded area and was destroyed. The pilot was killed and all four passengers were injured. They were en route to Ayaramã to provide dental assistance to locals. On board were one dentist, one assistant, one nurse and one employee of the Brazilian Institute for Geography and Statistics.
