## Discrepancy

ALL OF THE RT ENG PARAMETERS WERE LOST & A BANG WAS HEAR.  THE ENG WAS SHUT DOWN AS A PRECAUTION & THE ACFT RETURNED TO THE AIRPORT.  INVESTIGATION AFTER LANDING SHOWED THE RT OTBD & LOWER COWLS TO HAVE DEPARTED THE ACFT, ONE OR MORE STRIKING THE TAIL CONE & VERTICAL STABILIZER, NO PENETRATION OF SKIN NOTED.  THE TOP INBD COWL WAS PARTIALLY DETACHED & CRUMPLED TOWARDS THE FUSELAGE.  THE RETAINER STRAPS & COWL FASTENERS WERE LARGELY RETAINED WITH THE NACELLE STRUCTURE.
