BitmapMaterial + PhongShader + DAE. Why black lines on the material?

Greetings to all!

I connected dae model and imposed on it with the material shaders. At picture shows that on the material of black lines on some facets of the model. Please tell me how to remove them?

                        //Materials
                        var mp:MaterialsList = new MaterialsList();
                        var bp:BitmapAssetMaterial = new BitmapAssetMaterial("doggy_skin");
                        var sh = new PhongShader(light, 0xFFFFFF, 0x333333, 20);
                        var shbp:ShadedMaterial = new ShadedMaterial(bp, sh);
                        mp.addMaterial(shbp, "all");

                        //Model
                        dae = new DAE();
                        dae.load("doggy.dae",mp);
                        dae.moveDown(100);
                        dae.scale = 150;
                        dae.yaw = 180;
                        default_scene.addChild(dae);
