  of impact.
  ASSAULT ZONE AVAILABILITY REPORT
  6-136. The Zone Availability Report (ZAR) is a consolidated list of DZs and LZs maintained by HQ
  AMC for use by DoD aircraft. The direction and guidance for DZ and LZ operations is AFI 13-217. The
  ZAR currently contains both CONUS and OCONUS surveys forwarded by the owning command.
  Overseas zones are not controlled by AMC, but will be included, as they are also forwarded by the owning
  commands.
  6-137. To request survey of a new or existing zone, the commander contacts 720th STG/DOO, Hurlburt
  Field FL (DSN 579-6055). He should send new or updated DZ surveys to his nearest wing/group tactics
  office for a safety of flight review. He forwards completed DZ, LZ, and HLZ surveys to HQ AMC/DOKT
  for inclusion in the ZAR.
  6-138. To obtain a completed survey, he can use the fax-on demand system at Scott AFB, IL
  (DSN 576-2899), (Com (618) 256-2899). The Internet site available for military (.mil) users is located at
  https://amc.scott.af.mil/do/dok/zar.htm.

  AF IMT 3823, DROP ZONE SURVEY
  6-139. A drop zone survey is required for airborne operations. The two types of surveys are tactical and
  existing surveyed drop zones. Completing a DZ survey requires a physical inspection of the DZ and
  documentation of findings on AF IMT 3823. The using unit may complete the survey. The using unit is the
  one whose equipment or personnel is being airdropped. For exercises and joint training operations, users
  complete the survey and ensure the DZ meets the criteria for operational and safety standards. The user
  physically inspects the DZ before use to identify and evaluate potential hazards to the airdropped personnel
  or equipment, to man-made or natural structures, and to ground personnel. The DZST is qualified to survey
  the DZ and complete the AF IMT 3823. After completing all blocks that apply, the DZST sends the survey
  to the nearest active duty tactics office for review by the appropriate radio operator. The radio operator
  then forwards the survey to HQ, AMC TACC/DOOXY, who determines the proper approval authority and
  obtains the approval. After approval, the TACC/DOOXY enters the survey into the BBS, where it is then
  available for use. These procedures are used to approve surveys for all AMC, ACC, and AMC/ACC gained
  aircraft.
  SAFETY-OF-FLIGHT REVIEW
  6-140. The nearest group tactics office completes a safety-of-flight review on all DZ surveys. This
  review ensures that an aircraft can safely enter and leave the DZ. The review includes an in-depth chart
  study of the terrain features along the route of flight from the IP to about 4 nautical miles past the DZ
  trailing edge. For a complete list of regional group/wing tactics offices see
