National Transportation Safety Board officials said the front landing gear came down first, causing tires to blow out when the Boeing 737-700 hit the runway, the New York Daily News reported Thursday.
Investigators made the finding after studying videos of the landing and audio from cockpit recordings.
The plane was arriving at LaGuardia Airport Monday from Nashville when it made a hard landing and skidded down the runway before stopping in the grass without its front landing gear.
Ten people were treated at the scene for injuries and six of them were hospitalized.
