Airport (less than 10 km from airport)

While on an instrument approach for landing, the local tower air traffic controller observed on the BRITE radar repeater scope that the airplane passed the outer marker (OM), 600 feet below the permissible crossing altitude. The controller issued a low altitude alert to the pilot and cleared him to land. The controller also reminded the pilot that the minimum descent altitude for the Localizer Directional Aid (LDA) approach was 440 feet, and provided instructions for the missed approach. At that point the pilot reported that he had the airport in sight and acknowledged the landing instructions. The controller again cleared the pilot to land on the prescribed runway for the instrument approach, and the pilot acknowledged the landing clearance. Shortly thereafter the controller instructed the pilot to execute the missed approach as the radar track showed that the airplane was off course. The pilot was instructed to initiate a climbing left turn to the VOR. The pilot said he had the airport in sight and that he saw one of the cross runways and wanted to land. The controller told the pilot that circling to that runway was not an authorized procedure for the LDA approach and again instructed the pilot to perform the missed approach. A witness stated that he was working on a storage container, about 50 feet in height, when the airplane passed overhead. He estimated the airplane to be about 50 feet higher than the storage container. The airplane made a turn westbound and the witness looked away for a second. When he looked back the airplane was in a nose and left wing down attitude and then it impacted the ground. Another witness located on the airport's north-northeast corner also observed the airplane flying toward the airport. He reported simultaneously hearing the engine power up and observed the left wing stall prior to it impacting the ground. Both witnesses reported that they did not hear anything wrong with the engine. Examination of the airframe, power plant, and propeller revealed no mechanical anomalies that would have precluded normal operation. Internal damage signatures in the engine and propeller were consistent with the production of significant power at the time of impact. A review of the weather in the area revealed that while light rain and mist were occurring near the accident site, no meteorological phenomena existed that would have adversely affected the flight. The pilot and two passengers were killed while a third passenger, a boy aged 12, was seriously injured. He died from his injuries few hours later.

On approach to Monterrey-General Mariano Escobido Airport, the crew encountered poor visibility due to thick fog. On short final, the aircraft struck the ground, lost its undercarriage and came to rest in a rocky area located 400 metres short of runway. Both pilots escaped with minor injuries while the aircraft was damaged beyond repair.

The 7,660-hour airline transport rated pilot lost control of the twin-engine airplane while attempting to abort the landing. Dark night conditions prevailed for the attempted landing on runway 18. Runway 18 was reported to be 5,280-feet long, by 50 feet wide. The asphalt runway was reported to be dry and in good condition at the time of the accident. The pilot stated in the accident report (NTSB form 6120.1/2) that "I saw the one row of lights on short final and my mind played a trick on me. I had the thought that I was off-course and that those lights were houses." The pilot delayed making the decision to execute a go-around and by the time he added power the airplane had touched down in the "turnaround" area to the right of the approach end of runway 18. During the inadvertent touchdown the airplane rolled to the left and the left propeller struck the ground, resulting in damage to the left engine. The pilot added that he elected to retard the right engine to avoid losing control of the airplane and the airplane impacted the ground to the left of the runway. The airplane came to rest in an area of small bushes and mesquite trees. The pilot was able to egress the airplane unassisted through the main cabin door, and was not injured. A post-impact fire developed and consumed the airplane. The pilot reported that he was familiar with the airport and had operated several airplanes in and out of that location. Weather reported at Del Rio International Airport, located approximately 11 miles north of the accident site, was clear skies, 3 miles visibility, with winds from 150 degrees at 5 knots, temperature of 70 degrees Fahrenheit, and an altimeter setting of 29.95 inches of Mercury. The pilot added that he was not aware that the first 5 or 6 runway lights on the left side of the runway (at the approach end) were out of service when he initiated the night landing approach.

The crew was performing a positioning flight from Buenos Aires-Ezeiza-Ministro Pistarini Airport to Buenos Aires-Aeroparque-Jorge Newbury Airport. Before departure, the captain switched off the Stall Alarm System for unknown reasons. Shortly after takeoff from runway 17, the climb gradient was small and landing gear were retracted at a very low altitude. The left wing stalled and struck the runway surface. Out of control, the aircraft impacted ground, slid for few dozen metres, overran the runway and came to rest in a field. Both pilots were uninjured while the aircraft was damaged beyond repair.

Upon landing, the nose gear collapsed. The aircraft went out of control and veered off runway. While contacting soft ground, the left main gear collapsed as well, causing the left propeller to struck the ground. A propeller blade separated and penetrated the fuselage, and the aircraft came to rest on its belly. All occupants escaped uninjured while the aircraft was damaged beyond repair.

On short final to Mexicali Airport, the aircraft encountered windshear and lost height. The undercarriage struck the ground short of runway threshold and were torn off. The aircraft landed on its belly and slid for few dozen metres before coming to rest on the runway. There were no injuries but the aircraft was damaged beyond repair.

On the day of the accident, the pilot was returning to his home airport, after dropping off friends at a different airport. No weather briefing or flight plan was filed with Flight Service for either flight. A witness and radar data depicted the accident airplane on a straight-in approach for runway 1, in a landing configuration, at a ground speed of approximately 120 knots. The last radar target was recorded about 1/4 mile from the runway threshold, at an altitude of approximately 150 feet agl. The wreckage was later found about 1/2 mile east of the runway threshold. Review of weather information revealed general VFR conditions along the route of flight, and at reporting stations near the accident site. Gusty winds, low-level wind shear, and moderate to severe turbulence also prevailed at the time of the accident. In addition, weather radar depicted scattered light snow showers in the vicinity of the accident site, and possibly a snow squall. Examination of the wreckage did not reveal any preimpact mechanical malfunctions. The pilot had a total flight experience of 14,000 hours, with 8,500 hours in multiengine airplanes, including 2,600 hours in the same make and model as the accident airplane. He also had 4,100 hours of instrument flight experience.

The pilot, sole on board, was completing a demonstration flight on this second prototype to a group of invited guests staying on the ground. at Mindelheim-Mattsies Airport. Shortly after takeoff, the pilot completed a circuit to reach the approach pattern when the aircraft entered an uncontrolled descent and crashed in an open field located approximately 7 km from the airport. The aircraft disintegrated on impact and the French pilot Gérard Guillaumaud who was also the Chief Pilot by Grob Aerospace was killed.

After a normal takeoff roll from runway 29R at Tehran-Mehrabad Airport, the pilot-in-command pulled on the control column and started the rotation when one of the engine failed. Control was lost and the aircraft crashed, bursting into flames. Three passengers were seriously injured while 35 other occupants were killed. All three survivors died from their injuries few hours after the accident.

The single engine aircraft departed Tartu-Ülenurme Airport on a private flight to Dresden, carrying two passengers and one pilot. Shortly after takeoff, while climbing to a height of about 300-500 metres, the aircraft entered an uncontrolled descent and crashed in a field located about 500 metres past the runway end. All three occupants were seriously injured and rescued an hour later. The aircraft was destroyed.
