Да, нужно использовать onLoadError у слушателя mcl.

function createLoaderClip(createTo, src) {
	var d = createTo.getNextHighestDepth();
	var newClip = createTo.createEmptyMovieClip("loaderClip_"+d, d);
	var mcl = new MovieClipLoader();
	var loadListener = {};
	loadListener.onLoadInit = function(target_mc:MovieClip) {
		trace("loaded! "+target_mc._width+"x"+target_mc._height);
	};
	loadListener.onLoadError = function(target_mc:MovieClip, errorCode:String, httpStatus:Number) {
            trace(">> loadListener.onLoadError()");
            trace(">> ==========================");
            trace(">> errorCode: " + errorCode);
            trace(">> httpStatus: " + httpStatus);
	};
	mcl.addListener(loadListener);
	mcl.loadClip(src,newClip);
	return newClip;
}
for (var k = 0; k<10; k++) {
	var newLoaderClip = createLoaderClip(_root, "http://www.flasher.ru/forum/images/russian/flasher_logo.gif");
	newLoaderClip._y = k*80;
}
