Test

The crew departed Rodez-Marcillac Airport at 1715LT on a local test flight following a two-month maintenance period after the aircraft was suffering vibrations during preceding flights. On board were two pilots of Air Rouergue, two engineers from the same operator, a Fokker technician and one pilot from Air Alpes. The test program was short, about 15 minutes, with two circuits planned at an altitude of 7,000 feet over the Rodez beacon. On approach to runway 31, the crew was supposed to complete a level off at 4,400 feet QNH but continued the descent until the airplane struck a mountain shrouded in clouds and located about 17 km from the airport. One of the passenger was seriously injured while five other occupants were killed.

Technicians were engaged in ground tests at Malpensa Airport. While parked on the ramp, an engine run-up was initiated when the airplane jumped over the chocks and eventually struck obstacles and came to rest. There were no injuries.

The seaplane was engaged in a test flight out from Christiansted on behalf of the FAA. While flying off Christiansted, the pilot encountered engine problems and decided to ditch the aircraft few miles offshore. All three occupants were rescued while the aircraft was damaged beyond repair.

The aircraft was engaged upon a flight test for the renewal of its Certificate of Airworthiness (CofA). The sole occupants were the pilot and an observer. Following an ILS approach to runway 23 at Stansted Airport an overshoot (go-around) was initiated and at about 200 feet the starboard engine cut out. The commander attempted unsuccessfully to restart the engine by use of the starter motor. The aircraft lost speed and height and crashed just outside the airport. The observer was killed and the pilot injured.

The pilot, sole on board, was performing a local test flight at Mena Airport. During initial climb, one of the engine failed. He elected to return but misjudged his altitude and clearance when the airplane struck trees and crashed near the airport. The aircraft was destroyed and the pilot was injured.

The aircraft was engaged in a local test flight at Greybull Airport and was carrying one passenger and three crew members. After takeoff, while climbing, the crew encountered technical problems with the right engine. The captain elected to return and initiated a turn when the aircraft lost height and crashed. All three crew members were killed while the passenger was seriously injured.

Built by the Voronezh Aircraft Factory, the airplane came out of the plant last April 27. Test flights were conducted on April 27, May 12, 16 and 18. On May 23, the crew completed a fifth test flight from 1111LT and 1307LT without any incidents. At 1730LT, the crew departed Ramenskoye Airport near Moscow to proceed to a series of various tests on engines, generators, to evaluate the airtightness of the cabin as well as the stability and the controllability of the aircraft at an altitude of 12,000 meters. When all these checks were completed, the crew reduced his altitude to 3,000 meters then carried out the test of the auxiliary power unit (APU). For the next two minutes, engines n°3 and 4 were shut down in accordance with the test program. About a minute after the shutdown of the engine n°4, a burning smell was felt in the cabin and smoke spread through the air conditioning system, followed by a black and thick smoke. The captain decided to return to his departure point but quickly realized that this would be impossible. He reduced his altitude and attempted an emergency landing in a pasture. At a speed of 380 km/h, at an estimated height of four to six meters, the airplane struck and cut between 70 and 100 trees before falling to the ground. It then slid for about 620 meters before coming to rest in flames, some 46 kilometers southeast of Ramenskoye runway 30 threshold. Six crew members were rescued while two engineers were killed.

The crew departed Van Nuys for a local test flight. En route, a fire erupted in the left wheel well and spread to the left wing that detached in flight. Out of control, the airplane entered a dive and crashed in flames. All three occupants were killed.

The crew (two pilots and two technicians) departed d’Uherské Hradiště-Kunovice Airport for a local test flight on this third L-410 prototype. While cruising at a relative low altitude, the pilot-in-command lost control of the airplane that dove into the ground and crashed in a field located in Nedakonice, few km from the airfield. The aircraft was destroyed and all four occupants were killed.

In the morning, the crew completed two flights in the area. Due to engine problems, a technician was asked to make some engine test run. While the aircraft was parked on the ground, a technician proceeded to an engine test but forgot to install chocks on wheels. After the engine was started, power was added. The pilot who was standing by the door fell out of the plane that started to roll. After takeoff, the airplane climbed to a height of 12 meters, made a sharp turn to the left, stalled and crashed upside down. The technician, sole on board, was killed. It was determined that when the airplane started to roll quite roughly, the technician fell down from the pilot seat. Then, after liftoff, the cargo shifted to the rear of the cabin, causing the aircraft to stall.
