Takeoff (climb)

The crew was completing a local training flight at Antofagasta-Cerro Moreno Airport (Andrés Sabella Gálvez Intl Airport). At liftoff, the pilot-in-command initiated a sharp turn to the right, causing the left wing tip to struck the ground. Out of control, the aircraft crashed by the runway. All three occupants were injured and the aircraft was damaged beyond repair. It was reported that the pilot-in-command was a Mirage fighter jet captain. When ATC requested the crew to expedite the takeoff, the pilot-in-command made a sharp turn at low height, apparently not aware about the aircraft wingspan.

Upon reaching an altitude of 400 agl after takeoff, the left side door on the nose baggage door opened. The pilot-in- command initiated a left turn to return to the airport. During the turn the stall horn sounded. The airplane then descended and impacted the terrain. Investigation revealed that both pilots did a portion of the aircraft preflight inspection. Both pilots were qualified to act as PIC for the flight and this flight would typically have been a single pilot operation. However, the company who hired the operator to transport their employees requested two pilots. The operator did not have any written procedures regarding the division of duties for a two pilot operation on this type of aircraft.

The pilot reported the airplane decelerated during the takeoff roll. He applied the brakes and as he advanced the throttles to full power the airplane accelerated. The airplane cleared the end of the runway then stalled into Lake Michigan, flipped inverted and sank. One passenger reported that it felt as if someone put on the brakes. One passenger drowned. The pilot used 32' of manifold pressure for takeoff versus 37.3' as placarded. The pilot operating handbook lists normal takeoff speed as 91 KIAS, however the airplane was equipped with vortex generators. The pilot reported looking for 105 to 110 KIAS for takeoff. No evidence was found of the pilot having a multi-engine rating. No evidence of a mechanical failure/malfunction was found.

The aircraft was completing a flight from Agathi to Thiruvananthapuram with an intermediate stop in Cochin, carrying three passengers and three crew members. After takeoff from runway 17, at a height of about 400 feet, the aircraft pitched up steeply to a near vertical attitude and thereafter appeared to perform a manoeuvre similar to a stall turn to the right and crashed on the roof of the Component Repair Shop (CRS) building of the Naval Aircraft Yard. After impact the aircraft caught fire and was totally destroyed. All six occupants were killed as well as three people in the building. Six others received minor injuries.

The captain said the airplane felt 'sluggish' during the takeoff roll. At V1/Vr, the airplane was rotated for liftoff. It climbed 10 feet, 'shuddered,' and sank. The captain elected to abort the takeoff. He landed the airplane on the runway, applied brakes and deployed the drag chute. The drag chute separated and the airplane went off the runway, down a hill, through a fence, across a road and grassy area, across another road, through a chain link fence, and collided with a power pole. The captain said they had calculated the takeoff performance using inappropriate tables, and failed to consider the wet runway and wind shift. The drag chute riser fractured at a point where it passed through a lightning hole. The lightning hole bore no evidence of a nylon grommet having been installed.

After 33,5 seconds during the takeoff roll, after a distance of 975 metres and at a speed of 210 km/h, the engine n°4 failed and its propeller automatically feathered. For unknown reasons, the crew failed to identify this failure and the pilot-in-command started the rotation (elevator -26°) at an insufficient speed of 238 km/h instead of the recommended 250 km/h. After liftoff, the aircraft started to roll to the right, causing the right wing to struck the ground two seconds after rotation. The went out of control, lost its undercarriage, slid for about 300 metres and came to rest, bursting into flames. All nine occupants escaped with various injuries and the aircraft was destroyed by fire.

An aircraft mechanic working abeam of the point on the runway that the airplane lifted off was attracted by the sound of engine roughness, and observed black smoke trailing from the left engine. The airplane continued to climb to about 150 feet above ground level, entered a series of shallow left turns at about the airport's east boundary at a slow speed, and then entered a rapid left roll and pitched down. The pilot transmitted an unreadable call on FAA tower frequency, but the words, 'we got a..' and 'engine' were clearly discernable. The airplane crashed in dense brush about 1.25 miles northeast of the airport. Contamination was found in the left engine fuel system. Post crash testing of the left fuel servo revealed it would not sustain a steady state fuel flow above about one half throttle due to contamination.

The aircraft was engaged in a cargo flight from Ras al-Khaimah to Mykolaiv, carrying eight crew members and a load of various goods among them few tons of water melons. Following a night takeoff from runway 34 at a speed of 235 km/h, the aircraft reached the altitude of 150 metres at a speed of 365 km/h then continued to 160 metres at a speed of 400 km/h. The crew raised the flaps in five steps when the aircraft entered an uncontrolled descent with a rate of 12 metres per second until it impacted the sea at a speed of 485 km/h about 16 km from the airport, some 800 metres offshore. The aircraft disintegrated on impact and all eight occupants were killed.

During the takeoff roll at São Paulo-Congonhas Airport, the crew encountered an engine failure and decided to abort. The airplane was stopped on the main runway and all five occupants escaped uninjured. However, debris punctured a fuel tank and the aircraft caught fire and was severely damaged by fire and later written off.

Shortly after the airplane took off, a witness about 1 mile from the airport observed the airplane about 150 feet above the ground in a left turn, before it disappeared into the clouds. A witness across from where the airplane crashed stated he was in his shed when he heard the sound of an airplane overhead. When the sound faded and returned, like the airplane had circled above the shed, he stepped outside and looked for the airplane. He saw the airplane exit the clouds in a near vertical position and impact the ground. He described the engine noise as loud and smooth. The airplane impacted in a field about 3/4 miles from the departure airport and was consumed by a post crash fire. Streaks of oil were observed on the leading edge of the right horizontal stabilizer extending to its upper and lower surfaces. Disassembly of both engines did not reveal any pre-impact mechanical malfunctions. A weather observation taken after the accident reported included a visibility of 2 miles with light drizzle and mist, and the ceiling was 400 foot overcast. Witnesses described the weather at the accident site as '...pretty foggy,' and worse than the conditions reported at the airport.
