(4) DA  Form  2404.    Prepare  DA  Form  2404 as required in accordance with paragraph 9-7b. b. Preventative   Maintenance   Service.      Prior   to preserving a piece of equipment for storage perform the next scheduled major preventative maintenance service (quarterly,   semi-annual,   etc.      )   in   accordance   with applicable   technical   manuals,   lubrication   orders,   and technical   bulletins.      Equipment   discrepancies   will   be listed  on  DA  Form  2404  in  accordance  with  DA  Pam 738-750.  For equipment faults that create a Not Mission Capable   Supply   (NMCS)   equipment   status,   enter   the document  number(s)  of  the  associated  requisition(s)  in Column C. c. Cleaning.        An    essential    first    step    in    the preservation of AGSE is cleaning and drying.  Cleaning removes corrosive deposits such as soil, chemicals, bird dropping and exhaust residue and materials such as oil and  grease  that  will  attract  corrosive  deposits.    After cleaning,  the  item  will  be  thoroughly  dried  by  draining and/or   blowing   with   compressed   air.      AGSE   will   be thoroughly  cleaned  and  dried  prior  to  the  application  of the   preservation   procedures   in   applicable   equipment publications and this paragraph. d. Applicability.        AGSE    will    be    preserved    in accordance   with   the   applicable   equipment   technical manuals, lubrication orders, and technical bulletins.  The information  provided  in  this  paragraph  is  supplemental to the information contained in the applicable equipment publications. e. Processing.      In   the   absence   of   guidance   in specific equipment publications, ground support equip- ment   will   be   preserved   by   applying   the   techniques indicated below for equipment components applicable to the item being preserved. (1) Painted Metal Surfaces. (a) Cleaning.      Clean   surfaces   using, MIL-C87936,  cleaning  compound.    Clean  stubborn  or exceptionally    oily    areas    with    P-D-680    type    II    dry cleaning solvent.  Dry equipment. (b) Preservation.    Inspect  surfaces  for corrosion and treat in accordance with the procedures in TM 55-1500-344-23, aircraft weapons systems cleaning and  corrosion  control,  applicable  to  the  type  of  metal affected.  Bare spots and treated areas will be. (2) Non Painted Metal Surfaces. (a) Cleaning.      Clean   unpainted   metal surfaces   in   accordance   with   paragraph   9-7e   (1)   (a). Through  drying  is  particularly  important  for  unpainted surfaces. (b) Preservation.    Inspect  surfaces  for corrosion and treat in accordance with the procedure in TM   55-1500-204-23   applicable   to   the   type   of   metal affected.    Coat  unpainted  metal  areas  such  as  frames, rods,    springs,    and    pintle    assemblies    with    corrosion preventative  compound  MIL-C-16173,  Grade  3.    Coat light  metal  surfaces  such  as  the  inside  of  cowls  and access  panels  with  lubricating  oil  MIL-L-21260,  Type  I, grade 10. (3) Air   Compressors.      Clean   and   preserve exterior  surfaces  of  air  receivers  and  compressors  in accordance   with   paragraph   9-7a.      When   compressor lubricating    system    is    separate    from    the    associated power   unit,   drain   and   service   to   operating   level   with lubrication oil as specified in the equipment publications. Remove and service the air cleaner in accordance with paragraph 9-7e (8).  With the compressor running, spray lubricating oil MIL-L-21260, Type I, grade 10 into intake until  oil  appears  at  the  final  stage  discharge.    Drain  air receivers and lines of condensation.  Leave drain cocks open   and   attach   UU-T-81   warning   tag   to   operating controls stating "Close Drain Cocks Prior to Use.  " If the air receiver is located down stream of air oil separators, fog the receiver with MIL-L-21260, Type I, grade 10 oil. Coat   interior   steel   surfaces   of   the   pressure   regulator system  with  MIL-L-21260,  Type  I,  grade  10  lubricating oil.    Reinstall  air  filter  and  seal  all  compressor  opening with MIL-B-131, Class 3 barrier material and PPP-T-60, Type IV, class 1 tape. 9-20
