Dubai : A passenger jet circled a southern Russian airport in high winds and poor visibility, then crashed on a second landing attempt early Saturday, killing all 62 people aboard.

The flydubai Boeing 737 jet crashed at the Rostov-on-Don airport after traveling from Dubai.

Officials believe bad weather, which kept the plane from reattempting landing for more than two hours, likely caused the crash. They ruled out terrorism as a possibility.

Russia’s investigation into the crash will take about two months, investigative committee spokeswoman Oksana Kovrizhnaya said, as reported by state-run Sputnik News.

“But [the investigation] could be prolonged because of the inspections’ duration,” Kovrizhnaya added. He said the three potential causes being considered are technical issues, severe weather and human error.

The jet was carrying 55 passengers and seven crew members when it crashed, Emergencies Minister Vladimir Puchkov said.

It was scheduled to land at 1:20 a.m. (6:20 p.m. ET), but went down at 3:50 a.m. (8:50 p.m. ET), he said.

The airport is closed, and medics and psychologists are on standby to assist family members, he said.

About 700 people are involved in the rescue operation, the Ministry of Emergency Situations said. The crash site is 800 feet (243 meters) from the airport runway, it said.

Emergency staff found one of the plane’s flight recorders amongst the wreckage, state news reported.

The plane’s pilot circled the airport, waiting for the weather to clear before making a second attempt to land, but the aircraft’s tail had clipped the runway, it said.

State media reported winds of 97 kph (60 mph) at the time of the crash.

Workers at the crash scene have both of the plane’s flight data recorders and one of two voice recorders, state-run Ria Novosti reported.
