Subject  :Installation  of  Communication, Navigation  and  Radar 
          equipment.

1. PURPOSE

     Aircraft  Rule 9 sub-rule 3 and rule 57 specify  that  every 
     aircraft  shall be fitted and equipped with radio  apparatus 
     as  may be specified according to the use and  circumstances 
     under which the flight is to be conducted. This part of  the 
     CARs  describes  the  procedures  and  requirements  to   be 
     complied  with for installation of  airborne  communication, 
     navigation and radar equipment.

2. APPLICABILITY

     Whenever  it is desired to install a new radio equipment  on 
     aircraft or existing avionic installation is required to  be 
     replaced,  the following procedure is to be followed in  the 
     absence of manufacturer's guidelines.

2.1  The appropriately licenced AME/ Approved person shall make a 
     feasibility study to check that 

a)   The  proposed  equipment  is of the  approved  type  and  is 
     compatible with the existing system.
b)   Necessary electrical power is available in the aircraft  for 
     the proposed equipment.
c)   Required  space  is available at suitable  location  in  the 
     aircraft.
d)   C.G.   should   remain  within  the   limits   if   proposed 
     installation is carried out.

2.2  After feasibility study, an appropriately licensed AME shall 
     prepare    the   structural   installation    drawing    and 
     appropriately  licensed AME shall prepare the system  wiring 
     drawing.   Six   copies  of  the   drawing   alongwith   the 
     modification  details  shall  be  submitted  to  the   local 
     airworthiness office for approval.

2.3  On  receipt of formal approval, the installation work is  to 
     be  undertaken  by appropriately  licensed  AME/approved  or 
     authorised person.

2.4  On completion of the structural and electrical wiring  work, 
     the  complete  wiring shall be checked  for  continuity  and 
     insulation.  The  equipment  chassis shall  be  checked  for 
     proper bonding.

2.5  The AME should ensure the serviceability of the equipment by 
     checking   proper   maintenance/manufacturer's   certificate 
     issued  by an approved firm or carry out a Final  Test  Data 
     (FTD) check before the actual installation of the equipment.

2.6  The  AME should ensure that there is no  radio  interference 
     due  to installation of the new equipment which  affect  the 
     performance  of any other radio equipment installed  in  the 
     aircraft.

2.7  The   antenna   shall   be  suitably   insulated   so   that 

     precipitation static interference is minimum.

2.8  The equipment shall be installed and tested in the  aircraft 
     by  the  AME  and all relevant  paperwork/entries  shall  be 
     completed by him.

2.9  The  empty weight and C.G. shall be amended  accordingly  by 
     the appropriately licenced AME/ authorised/ approved person.

2.10 In case the installation is new or the existing one is being 
     replaced a short term aeromobile license for operating radio 
     apparatus  is  to be obtained from WPC Wing of  Ministry  of 
     Communications.  For  the purpose,  registered  owner  shall 
     apply  in  quadruplicate on the prescribed  form  (available 
     from  WPC Wing, Ministry of Communication) alongwith a  copy 
     of  Certificate  of registration and requisite  fee  to  the 
     Wireless  Advisor,  Ministry of  Communication  through  the 
     local  airworthiness  office, who shall forward  it  to  the 
     DGCA.  The Certificate of inspection is to be signed  by  an 
     appropriately licensed AME indicating his license number  on 
     the application.

2.11 On  receipt  of  the short term permit  the  operator  shall 
     complete  all the installation checks including  ground  and 
     flight   tests  as  per  the  approved  installation   check 
     schedule.  The  operator shall prepare the schedule  of  the 
     above  tests based on the guidelines contained in  the  BCAR 
     Section R and FAA Advisory Circular AC 43-13 and forward  it 
     to  the local Airworthiness office for approval. The  flight 
     tests  referred to above shall be carried out to assess  the 
     range  and  performance  of the  new  equipment  in  various 
     altitudes  of  flight and to check  the  compatibility  with 
     other radio equipment installed in the aircraft.

2.12 On  receipt of the installation check report vide  2.11  the 
     aircraft  shall be offered for inspection and  communication 
     check to the local airworthiness office. 

2.13 After the satisfactory checks the operator should obtain the 
     regular aeromobile license from the WPC Wing of the Ministry 
     of   Communication  by  applying  in  the  prescribed   form 
     (Appendix  'A') through the local airworthiness  office  who 
     will forward the same to the DGCA alongwith a  communication
