## Analysis

THE ACFT MADE A HARD LANDING ON A FROZEN LAKE DURING A PRECAUTIONARY LANDING. THE PLT SAID THAT CARGO ON BOARD HAD SHIFTED IN FLT AND HE ALSO HAD A LOSS OF 15 MPH IN AIRSPEED. THINKING IT MIGHT BE AN ICING PROBLEM, THE PLT MADE THE UNSCHEDULED LANDING. NO ICE WAS FOUND ON THE ACFT AFTER LANDING BUT THE ACFT WAS SUBSTANTIALLY DAMAGED BY THE IMPACT.
