Flight

While descending to Urimán Airport following an uneventful flight from La Paragua, the crew encountered an unexpected situation and attempted an emergency landing when the aircraft impacted ground and came to rest against a group of palm trees located 13 km from Urimán. Both pilots were injured and the aircraft was damaged beyond repair.

The airplane departed Las Vegas-McCarran Airport at 1452LT on a charter flight to Monterrey, carrying two pilots and 11 passengers who were returning to Mexico after taking part to a boxing match in Las Vegas. The flight was completed at FL370 until the crew was cleared to climb to FL390 for five minutes then to FL410. Suddenly, the airplane entered an uncontrolled descent and eventually crashed in an almost flat attitude in a desert area located near La Rosita, Coahuila. The aircraft was destroyed by impact forces and a post crash fire and all 13 occupants were killed. The wreckage was found the following day.

On 01 May 2019 at 0723, the aircraft departed CYYR on a VFR flight plan direct to BGBW. The ferry pilot, who was the pilot-in-command, occupied the left seat while the co-owner occupied the right seat. The aircraft climbed to 2000 feet ASL and proceeded on a direct track to destination. The altitude and heading did not change significantly along the route, therefore it is likely that the autopilot was engaged. At 0816, the aircraft collided with a snow-covered hill 2250 feet in elevation, located 35 nautical miles (NM) southeast of Makkovik Airport (CYFT), Newfoundland and Labrador. The impact happened approximately 200 feet below the top of the hill. The aircraft came to rest in deep snow on steep sloping terrain. The aircraft sustained significant damage to the propeller, nose gear, both wings, and fuselage. Although the cabin was crush-damaged, occupiable space remained. There was no post-impact fire. The ferry pilot was seriously injured and the co-owner was fatally injured. The Joint Rescue Coordination Centre (JRCC) in Halifax received an emergency locator transmitter (ELT) signal from the aircraft at 0823. The ferry pilot carried a personal satellite tracking device, a personal locator beacon (PLB) and a handheld very high frequency (VHF) radio, which allowed communication with search and rescue (SAR). Air SAR were dispatched to the area; however, by that time, the weather had deteriorated to blizzard conditions and aerial rescue was not possible. Ground SAR then deployed from the coastal community of Makkovik and arrived at the accident site approximately 4 hours later because of poor weather conditions and near zero visibility. The ferry pilot and the body of the co-owner were transported to Makkovik by snowmobile. The following day, they were airlifted to CYYR.

Two instrument-rated commercial pilots and one passenger were conducting a cross-country flight in instrument meteorological conditions when they began discussing an electrical malfunction; they then reported the electrical problem to air traffic control. The airplane subsequently made a descending right turn and impacted wooded terrain at a high speed. Most components of the airplane were highly fragmented, impact damaged, and unidentifiable. Based on the limited discussion of the electrical problem on the cockpit voice recorder and the damage to the airplane, it was not possible to determine the specific nature of the electrical malfunction the airplane may have experienced. While it was not possible to determine which systems were impacted by the electrical malfunction, it is possible the flight instruments were affected. The airplane's descending, turning, flight path before impact is consistent with a system malfunction that either directly or indirectly (through a diversion of attention) led to the pilot's loss of awareness of the airplane's performance in instrument meteorological conditions and subsequent loss of control of the airplane.

In the morning, the Guatemala Army Forces were informed by ATC that a PA-31 entered the Guatemala Airspace without prior permission. The twin engine airplane crashed in a wooded area located near the farm of Sepens located in the region of Sayaxché, Petén. The aircraft was partially destroyed by impact forces and both occupants were killed. A sticker was set on the fuselage with the registration N2613 which is wrong.

The twin engine airplane departed Venezuela in the evening on a probable drug smuggling flight with an unknown destination. At 2226LT, after it entered the Dominican Airspace, a crew of the Dominican Air Force was dispatched with an Embraer EMB-314 Super Tucano but the PA-31 disappeared from radar screens at 2228LT after crashing in a sugar cane field located in the region of San Rafael de Yuma, between La Romana and Punta Cana. Due to limited visibility caused by night and poor weather conditions, SAR operations were suspended shortly after midnight. The wreckage was found in the next early morning. Nobody was found on site and the aircraft is probably written off. The registration YV312 may be a wrong one.

Earlier in the afternoon the pilot was an uninvited guest at a private function that was held at the Matsieng Flying Club facility at Matsieng Aerodrome. In a statement, the Matsieng Flying Club reported that it was rumored that the pilot was involved in a domestic dispute earlier in the afternoon. At 2015LT the aircraft approached Matsieng Aerodrome from the direction of Sir Seretse Khama Airport and made a number of low level fly passes from different directions past the Club facilities next to the Air Traffic Control tower. An immediate evacuation of the club premises was ordered. The final extreme low level run by the aircraft along runway 36 resulted in an impact with the Matsieng Flying Club facility at ground level. The Club facility and Matsieng ATC tower was destroyed on impact. The post impact fire destroyed 13 parked vehicles. The emergency services of the Kgatleng District Council were on the scene within minutes to attend to the post-impact fire and distress. These response actions are to be commended. It is believed that the pilot had no permission to fly the aircraft involved. Sole on board, he was killed.

The commercial pilot was conducting an aerial observation (surveying) flight in a piston engineequipped multiengine airplane. Several hours into the flight, the pilot advised air traffic control (ATC) that the airplane had a fuel problem and that he needed to return to the departure airport. When the airplane was 8 miles from the airport, and after passing several other airports, the pilot informed ATC that he was unsure if the airplane could reach the airport. The final minutes of radar data depicted the airplane in a descent and tracking toward a golf fairway as the airplane's groundspeed decreased to a speed near the single engine minimum control airspeed. According to witnesses, they heard an engine sputter before making two loud "back-fire" sounds. One witness reported that, after the engine sputtered, the airplane "was on its left side flying crooked." Additional witnesses reported that the airplane turned to the left before it "nose-dived" into a neighborhood, impacting a tree and private residence before coming to rest in the backyard of the residence. A witness approached the wreckage immediately after the accident and observed a small flame rising from the area of the left engine. Video recorded on the witness' mobile phone several minutes later showed the airplane engulfed in flames. Examination of the wreckage revealed no evidence of any preimpact mechanical malfunctions or failures of either engine. The fuel systems feeding both engines were damaged by impact forces but the examined components generally displayed that only trace amounts of fuel remained; with the exception of the left engine nacelle fuel tank. Given the extent of the fire damage to this area of the wreckage, and the witness report that the post impact fire originated in this area, it is likely that this tank contained fuel. By design, this fuel in this tank was not able to supply fuel directly to either engine, but instead relied on an electric pump to transfer fuel into the left main fuel tank. Fire damage precluded a detailed postaccident examination or functional testing of the left nacelle fuel transfer pump. Other pilots who flew similar airplanes for the operator, along with a review of maintenance records for those airplanes, revealed at least three instances of these pumps failing in the months surrounding the accident. The other pilots also reported varying methods of utilizing fuel and monitoring fuel transfers of fuel from the nacelle fuel tanks, since there was no direct indication of the quantity of fuel available in the tank. These methods were not standardized between pilots within the company and relied on their monitoring the quantity of fuel in the main fuel tanks in order to ensure that the fuel transfer was occurring. Had the pilot not activated this pump, or had this pump failed during the flight, it would have rendered the fuel in the tank inaccessible. Given this information it is likely that the fuel supply available to the airplane's left engine was exhausted, and that the engine subsequently lost power due to fuel starvation. The accident pilot, along with another company pilot, identified fuel leaking from the airplane's left wing, about a week before the accident. Maintenance records showed no actions had been completed to the address the fuel leak. Due to damage sustained during the accident, the origin of the fuel leak could not be determined, nor could it be determined whether the fuel leak contributed to the fuel starvation and eventual inflight loss of power to the left engine. Because the left engine stopped producing power, the pilot would have needed to configure the airplane for single-engine flight; however, examination of the left engine's propeller found that it was not feathered. With the propeller in this state, the pilot's ability to maintain control the airplane would have been reduced, and it is likely that the pilot allowed the airplane's airspeed to decrease below the singleengine minimum controllable airspeed, which resulted in a loss of control and led to the airplane's roll to the left and rapid descent toward the terrain. Toxicology results revealed that the pilot had taken doxylamine, an over-the-counter antihistamine that can decrease alertness and impair performance of potentially hazardous tasks. Although the toxicology results indicated that the amount of doxylamine in the pilot's cavity blood was within the lower therapeutic range, review of ATC records revealed that the pilot was alert and that he was making necessary decisions and following instructions. Thus, the pilot's use of doxylamine was not likely a factor in the accident.

The aircraft was engaged in an illegal flight, carrying two pilots and a load of 200 kg of cocaine. En route, the crew apparently encountered an unexpected situation and was forced to attempt an emergency landing when the airplane crashed in a wooded area located near San Pedro de Peralta. A pilot was killed while the second was seriously injured. Originally registered N299GS, the aircraft was cancelled from the US registered on 15 February 2018 and exported to Mexico. The registration N18BA is false.

The twin engine airplane departed San José del Guaviare on a charter flight to Villavicencio, carrying 11 passengers and three crew members. While cruising at an altitude of 8,500 feet in good weather conditions, the left engine failed due to an important fuel leak. The crew elected to secure the engine but was unable to feather the propeller. The airplane lost speed and height, and while attempting an emergency landing, the crew lost control of the airplane that stalled and crashed in a palm plantation, bursting into flames. The aircraft was totally destroyed by a post crash fire and all 14 occupants were killed.
