on board. It is normally signed by the V-4 division officer and submitted to each of the following officers: · Commanding officer · Air  officer · Engineering officer · Operations officer · Officer of the deck · Supply officer CASUALTY  REPORTING The  casualty  report  (CASREP)  has  been  designed to support the Chief of Naval Operations (CNO) and fleet  commanders  in  the  management  of  assigned forces. The effective use and support of Navy forces require  an  up-to-date,  accurate  operational  status  for each unit. An important part of operational status is casualty information. The reporting of casualties re- sults  in  operational  commanders  and  support  person- nel   being   advised   of   the   status   of   significant equipment  malfunctions  that  could  result  in  the  deg- radation of a unit’s readiness. The CASREP also re- ports the unit’s need for technical assistance and/or replacement parts to correct the casualty. A casualty is defined as an equipment malfunction or deficiency that cannot be corrected within 48 hours that · reduces the unit’s ability to perform a primary mission, or · reduces the unit’s ability to perform a secon- dary  mission,  or · reduces  a  training  command’s  ability  to  per- form its mission, or a significant segment of its mission, and cannot be corrected or adequately accommodated   by   rescheduling   or   double- shifting  lessons  or  classes. The CASREP system contains four types of re- ports: initial, update, correct, and cancel. These re- ports   are   described   in   general   in   the   following paragraphs.  For  more  complete  information  on  prepa- ration and submission of the reports, see  Operational Reports.   NWP  10-1-10.  (Formerly  NWP  7,  Revi- sion A.) Initial  Casualty  Report (Initial) An Initial casualty report identifies the status of the casualty and any parts and/or assistance that is needed.  Operational  and  staff  authorities  use  this  in- formation  to  set  priorities  for  the  use  of  resources. Update  Casualty  Report (Update) An Update casualty report contains information similar to that submitted in the Initial report and/or submits changes to previously submitted information. Correction  Casualty  Report (Correct) A unit submits a correction Correct casualty report when equipment that has been the subject of casualty reporting is repaired and back in operational condi- tion. Cancellation  Casualty  Report (Cancel) A  unit  submits  a  cancellation  Cancel  casualty  re- port  when  equipment  that  has  been  the  subject  of casualty  reporting  is  scheduled  to  be  repaired  during an overhaul or other scheduled availability. Outstand- ing casualties that will not be repaired during such availability will not be canceled, and will be subject to  normal  follow-up  casualty  reporting  procedures  as specified. SURVEYS The  purpose  of  surveys  is  to  determine  the  reasons and/or  responsibilities  for  the  loss,  damage,  or  de- struction  of  Government  material  and  to  determine  the actual loss to the U.S. Government. Immediately upon the discovery of the loss, damage, or destruction of Government material, a preliminary investigation is conducted. The investigation is conducted to deter- mine if there is evidence of negligence, willful mis- conduct,   or   deliberate   unauthorized   use.   This preliminary  investigation  is  conducted  by  the  depart- ment head or division officer (or equivalent) respon- sible for the material. When circumstances warrant, such  as  an  indication  of  criminal  action  or  gross  neg- ligence,  the  CO  or  OIC  may  appoint  a  surveying officer or a survey board to investigate the situation further.  However,  individuals  who  are  accountable  or 8-6
