Решил задачку так:

function fnPanelPassportAdd() {
        var PanelPassport = new Ext.FormPanel({
            title: txtPassport,
            id: "PanelPassport",
            frame: true,
            monitorValid: true,
            defaultType: 'textfield',
            items: [
                {
                    xtype: 'textfield', fieldLabel: txtSeries, name: "DirContractorPasSeries", width: 420, allowBlank: false
                },
                {
                    xtype: 'textfield', fieldLabel: txtNumber, name: "DirContractorPasNumber", width: 420, allowBlank: false
                },
                {
                    xtype: 'textfield', fieldLabel: txtPinCode, name: "DirContractorPasPinCode", width: 420, allowBlank: false
                },
                {
                    xtype: 'textfield', fieldLabel: txtIssued, name: "DirContractorPasIssued", width: 420, allowBlank: false
                },
                {
                    xtype: 'datefield', format: "d.m.y", maxValue: new Date(), fieldLabel: txtDate, name: 'DirContractorPasDate', allowBlank: false
                }
            ]
        });
        DirContractorTabPanel.add(PanelPassport);
    }
    function fnPanelPassportRemove() {
        var tab = Ext.getCmp("PanelPassport"); DirContractorTabPanel.remove(tab, true);
    }
