if you want to pass an array to mvc engine, send the input multiple times. change your code to the following :

function sendForm(projectId, target) {
var useraccountIds = new Array(1, 2, 3);
var data = { projectId: projectId };
for (var i = 0; i < useraccountIds.length; i++) {
  $.extend(true, data, {useraccountIds: useraccountIds[i]});
}
$.ajax({
    traditional: true,
    url: target,
    type: "POST",
    data: data,
    success: ajaxOnSuccess,
    error: function (jqXHR, exception) {
        alert('Error message.');
    }
});

}
