TM   55-3930-660-14 CHAPTER  5 AIR  TRANSPORT Section   I. 5-1.    General The  6K  VRRTFL  is  air  transportable.  The  ship- ping  unit  must  ensure  that  the  VRRTFL  is  prop- erly prepared for air transport before reaching the marshaling area. The shipping unit will assist the aircraft   loadmaster/crew   in   loading   and   tying down the VRRTFL. The loadmaster-prepared load plan for the actual aircraft mission will determine specific  loading  limitations,  tiedown  patterns,  and troop   seating   availability.   The   loading   restraint factors (LRF) used in aircraft tiedown are listed in appendix  B. 5 - 2 .     S a f e ty Safety  considerations  and  precautions  for  the  6K VRRTFL air transport are: **CAUTION** Personnel   must   wear   ear   protection (plugs)  at  all  times  while  working  on  the flightline. GENERAL Members  of  loading  teams  should  not wear rings. *NOTE* Fire  extinguishers  must  be  readily  avail- able  during  aircraft  loading  and  unload- ing   operations. The   vehicle   maximum   speed   within   25 feet  of  any  aircraft  is  5  mph.  On  loading ramps  or  inside  the  aircraft,  the  vehicle should not exceed 3 mph. Personnel  must  not  refuel  or  otherwise service  the  VRRTFL  within  50  feet  of  an aircraft. 5-3.    Hazardous    Material Shippers  must  provide  written  notification  before shipping dangerous or hazardous materials aboard military  or  DOD  contract  aircraft.  Details  are covered  in  TM  38-250/AFR  71-4,  Preparation   of Hazardous  Materials  for  Military  Air  Shipment. Section   II.   TRANSPORT   by   CARGO   AIRCRAFT 5-4.   USAF   Cargo   Aircraft The  6K  VRRTFL  is  certified  for  airlift  aboard  all Military  Airlift  Command  (MAC)  prime  mission cargo  aircraft.  Airlift  on  the  C-130  will  require removal  of  the  3,600-pound  counterweight  to  re- duce axle load. 5-5.   Civil   Reserve   Air   Fleet   (CRAF) The  6K  VRRTFL  exceeds  the  capability  of  all aircraft in the CRAF. 5-6.   Preparation The deploying unit must prepare the VRRTFL for airlift. Preparation will include: a. Cleaning dirt, mud, snow, ice, and trash from the VRRTFL. b. Ensuring the VRRTFL has no fluid leaks (oil, fuel, hydraulic, and coolant). c. Ensuring  the  VRRTFL  is  in  good  mechanical order,   with   usable   tiedowns;   operating   engine, brakes,  and  hydraulic  system;  and  proper  tire pressure. d. Marking  the  shipping  weight  and  center  of balance location on both sides of VRRTFL. e. Securing battery, and tightening battery caps. f. Filling  the  VRRTFL  fuel  tank  between  one- quarter and one-half full, and securely closing fuel tank to prevent spillage. *NOTE* Fuel  tank  can  be  no  more  than  one-half full on other than contingency flights. g.  When   required,   remove   and   palletize   the counterweight. The VRRTFL Unit, Direct Support, and  General  Support  Maintenance  Manual,  TM 10-3930-660-24,  provides  details  on  counter- weight removal and installation. *NOTE* A  second  forklift  truck  is  needed  to  re- move  the  VRRTFL  counterweight.  Re- moval  requires  lifting  the  3,600-pound counterweight on the fork ends. A forklift truck  with  a  minimum  capacity  of  5,000 pounds  (using  standard  forks)  will  be needed to handle the counterweight. 5-1
