## Discrepancy

IN JANUARY, AN ELT WAS INSTALLED WITH ANTENNA CI 248-5 INSTALLED WITH A DOUBLER.  THE DOUBLER WAS TIED INTO THE EXISTING 2 STRINGERS ON THE LT AND RT.  3 MONTHS LATER THE SKIN AND DOUBLER CRACKED AROUND THE BASE OF THE ANTENNA AND UPON LANDING THE ANTENNA DEPARTED THE AIRCRAFT.  IT REMAINED ATTACHED BY THE COAX CABLE.  THE ANTENNA WAS UNDAMAGED, A DER WAS BROUGHT IN AND A FLUSH PATCH INSTALLED.  A NEW DOUBLER WAS FABRICATED AND THE NEW DOUBLER TIED INTO THE 2 STRINGERS ALONG WITH THE FWD AND AFT FRAMES.
