AIRCRAFT PERFORMED A TECHNICAL LANDING AT CUL DUE TO WHEATEAR CONDITIONS AT HMO. AT CUL CAPTAIN REPORTED THAT DURING TURNS THE RADAR GOES OUT OF SERVICE, SO VERTICAL GYRO NR 2 WAS REPLACED IAW MM 34-23-00, TESTED CORRECT. AIRCRAFT WAS DISPATCHED AND CAPTAIN REPORTED THAT DURING TURNS ADI GOES OUT OF SERVICE, SPHERE AT 90 GRADES WITH FAIL FLAG, AUTOMATIC PILOT DISENGAGE, FMA WITH NO AUTO-LAND LIGHTS, AND NO ECHO’S WERE REGISTERED AT 40 MILES OR LEAST.
