Army personnel, send your comments on DA Form 08 directly to: Director Aerial Delivery and Field Services Department USA Quartermaster Center and School 00 Shop Road Fort Lee, Virginia Air Force personnel, send your reports on AFTO Form through: Headquarters Air Mobility Command (AMC/DOKT) 40 Scott Drive, Unit 3AI Scott AFB, Illinois Air Force personnel in Special Operations Command, send your reports on AFTO Form through: HQ AFSOC/DOXT 00 Bartley Street, Suite 60 Hurlburt Field, FL to: Director Aerial Delivery and Field Services Department USA Quartermaster Center and School 00 Shop Road Fort Lee, Virginia Also send an information copy of AFTO Form to: SA-ALC/TILDP 485 Quentin Roosevelt Road Kelly AFB, Texas ix

30 CHAPTER INTRODUCTION -. Description of Items The 500-gallon-capacity collapsible fabric fuel drums can be dropped with or without the 50- gallon-per-minute pumping assembly or liquid fuel filter/separator (filter) in the following configurations: a. One or two drums with a pumping assembly on a type II airdrop platform for low-velocity airdrop from a C-30 or C-4 aircraft. b. Two or three drums without a pumping assembly on a type II airdrop platform for lowvelocity airdrop from C-30 and C-4 aircraft. Two to seven drums without a pumping assembly are rigged on a type V airdrop platform for low-velocity airdrop from C-30, C-4, C-5, and C-7 aircraft. c. Three, six, or seven drums with a pumping assembly on a type V airdrop platform for low-velocity airdrop from C-30, C-4, C-5, and C-7 aircraft. d. Two to five drums with or without a pumping assembly or a liquid fuel separator (filter) on a LAPES airdrop platform for LAPE airdrop from a C-30 aircraft. e. Two to five drums without a pumping assembly on a type V airdrop platform for LAPE airdrop from a C-30 aircraft. -. Special Considerations CAUTION There must be no more than 43 gallons of liquid in each drum when the drum is rigged for low-velocity and LAPE airdrops. a. These loads may contain hazardous materials- gasoline, JP-4 fuel, or diesel fuel. Hazardous materials in these loads must be packaged, marked, and labeled in compliance with AFJMAN 4-04/ TM b. Gasoline, JP-4 fuel, or diesel fuel may be airdropped using these procedures. Each drum must be weighed to learn its exact weight. For computing liquid weight per US gallon, use 6 pounds for gasoline, 6.6 pounds for JP-4 fuel, and 6.68 pounds for diesel fuel. c. The drum is flexible, and will rebound on impact. The lashings may break and cause the drum to roll off the platform and create a possible hazard in the area. d. A copy of this manual must be available to the joint airdrop inspectors during the before- and after- loading inspections. WARNING Do not add air to drums. Changes in pressurization can cause leaking or bursting. Failure to comply endangers mission, aircraft, -
