(CNN) Bad weather and possible 'crew error' appeared to be an early focus of an inquiry into what caused a Boeing 747 freighter to crash Monday in a village near Kyrgyzstan's capital.

The jumbo Turkish freighter slammed into the village of Dacha-Suu on the outskirts of Bishkek, killing 37 people and destroying at least 15 houses, Kyrgyzstan's emergency situations ministry said.

Kyrgyz Deputy Prime Minister Muhammetkaly Abulgaziev blamed the crash on "crew error," but offered no details about the claim.

The deputy prime minister said on Kyrgyzstan's state-run Kabar news agency that the government had reviewed preliminary information from the accident. Air accident investigations typically take months.

A thick mist caused poor visibility at the time of the crash and was being cited as a possible contributor to Monday's crash. Abulgaziev said other planes landed safely at Manas airport before the crash.
