Narrative:
A dangerous 1000 ft MSL tower (420 ft AGL) exists on the 192 degree radial off the cgi VOR at 10 DME. This tower lies perilously on the centerline of the VOR2 approach course to cgi. This tower is clearly depicted on the sectional charts, but is not marked on govt approach plates! The govt approach plate vertical profile requires a procedure turn within 10 miles of the VOR, but the MDA on the inbound course specifies a descent MDA of 1000 ft MSL! A pilot might easily find the top of the tower on this approach with the slightest anomaly in airborne or ground DME equipment. No room for error. Nothing alerts the unsuspecting pilot of the existence of the hazard on the approach plate. Please mark the tower on all govt and commercial approach plates for all approachs. Please amend the VOR2 approach. A 2000 ft procedure turn followed by a descent to only 1500 ft MSL inbound until reaching a new stepdown fix at a 5 mi DME fix would produce a safe result

Title: A BE-36 PLT EXPRESSES CONCERN THAT THERE IS AN UNCHARTED OBSTACLE LOCATED IN AN AREA THAT REQUIRES A PROC TURN ON A VOR APCH.
Narrative: A DANGEROUS 1000 FT MSL TWR (420 FT AGL) EXISTS ON THE 192 DEGREE RADIAL OFF THE CGI VOR AT 10 DME. THIS TWR LIES PERILOUSLY ON THE CENTERLINE OF THE VOR2 APCH COURSE TO CGI. THIS TWR IS CLEARLY DEPICTED ON THE SECTIONAL CHARTS, BUT IS NOT MARKED ON GOVT APCH PLATES! THE GOVT APCH PLATE VERTICAL PROFILE REQUIRES A PROC TURN WITHIN 10 MILES OF THE VOR, BUT THE MDA ON THE INBOUND COURSE SPECIFIES A DSCNT MDA OF 1000 FT MSL! A PLT MIGHT EASILY FIND THE TOP OF THE TWR ON THIS APCH WITH THE SLIGHTEST ANOMALY IN AIRBORNE OR GND DME EQUIP. NO ROOM FOR ERROR. NOTHING ALERTS THE UNSUSPECTING PLT OF THE EXISTENCE OF THE HAZARD ON THE APCH PLATE. PLEASE MARK THE TWR ON ALL GOVT AND COMMERCIAL APCH PLATES FOR ALL APCHS. PLEASE AMEND THE VOR2 APCH. A 2000 FT PROC TURN FOLLOWED BY A DSCNT TO ONLY 1500 FT MSL INBOUND UNTIL REACHING A NEW STEPDOWN FIX AT A 5 MI DME FIX WOULD PRODUCE A SAFE RESULT
