and now let's blame the crew.......
The Interstate Aviation Committee is considering several theories of the Il-86 crash that occurred outside Sheremetyevo-1 airport on July 28, including human error, Committee Vice Chairman Rudolf Teimurazov told a press conference in Moscow on Wednesday.
"We are examining several theories, including an error of the crew," Teimurazov told the press.
He announced that the investigation will be over by the end of August. Its field stage will last for two weeks and the laboratory stage for another two weeks.
The plane took off 38 seconds after it started moving. After two seconds, the stabilizer shifted from 3 degrees to 12 degrees, which caused the plane to rise sharply, fall on its side and dive into the ground. It had risen to an altitude of about 600 meters, and its weight at take-off was about 150 tonnes.
Teimurazov said experts have sufficient information to assert that the stabilizer shift was caused by the working of the hydraulic motors.
Experts have discovered that all of the hydraulic motors operating the stabilizer worked normally, he said, adding that the stabilizer control system has a triple control reserve and a four- fold power reserve.
All of the plane's four engines were working normally until the plane crashed into the ground.
Teimurazov said the absence of a conversation record on the flight recorder was caused by the flight recorder's failure.
The Il-86 was made in October 1983. Planes of this class have a service life of 20 years, which is normally extended to 30 years. The plane's initial flight resource is 22,000 hours. The plane that crashed had a flight record of 18,370 hours.
