Moscow, Dec. 31 (Xinhua) -- The condition of the runway was not the cause of an air crash at Moscow's Vnukovo airport, the Interstate Aviation Committee said Monday.
The runway had been cleared about one and a half hours before the crash, and the friction coefficient was rechecked 15 minutes after the incident, the committee said in a statement.
"It (friction coefficient) stood at 0.63, which satisfies the landing requirements for this kind of airplane," the statement said.
The Tu-204 passenger plane, operated by Russian airline Red Wings, slid off the runway and broke into three parts while landing at the country's third busiest airport.
Five people were killed and three injured. All eight were crew members on the plane, which was carrying no passengers.
The Moscow city transport prosecutor's office has launched a criminal investigation into the case.
The Moscow municipal government promised Sunday each victim's family would receive a million rubles (32,000 U.S. dollars) in compensation.
