Eurocopter is concerned that operators use only genuine Eurocopter helicopters and are not misled into buying or operating aircraft which were destroyed and then rebuilt by others without Eurocopter's involvement. Such aircraft, sometimes rebuilt around their identification data plate, are counterfeit and are not Eurocopter products.
You have no assurance that they will have the same quality and safety of genuine Eurocopter aircraft. Following the investigation of an aircraft accident by the appropriate governmental authority, the damage to the aircraft is typically identified as being minor or substantial, in which case the aircraft can be repaired by authorized facilities using the necessary approved manuals and procedures and specified parts, tools and jigs. However, if the aircraft is officially determined to have been destroyed, it cannot be rebuilt except by the manufacturer under the rules established in EASA approved documentation.
To protect against the potential sale or operation of such counterfeit aircraft, Eurocopter recommends that anyone considering purchasing or rebuilding any destroyed aircraft checks the following 3 lists, which began tracking destroyed aircraft on January 1, 2009:

• List of Eurocopter Destroyed Aircraft with Data Plate Destroyed / Serial Number Retired: (coming soon)
  Eurocopter requests that certification authorities remove the aircraft’s serial number from the Type Certificate Data Sheet for each aircraft which has been officially determined to have been destroyed and has its data plate destroyed.
  Eurocopter will not knowingly support such destroyed aircraft, as is done for genuine Eurocopter products.
  
  
• List of Eurocopter Destroyed Aircraft without Data Plate Destroyed / Serial Number Retired: (coming soon)
  This list concerns officially destroyed aircraft whose data plates have not been recovered yet for destruction and as a consequence corresponding serial numbers have not been retired yet. This list is updated periodically as final governmental accident reports are received. Eurocopter will not knowingly support such destroyed aircraft, as is done for genuine Eurocopter products.
  

• List of Potentially Destroyed Eurocopter Aircraft
  
  This is a list of potentially destroyed Eurocopter aircraft for which a governmental agency or other organization has indicated the aircraft has been destroyed, but for which a final official accident report has yet to be issued.
  Eurocopter will continue supporting these aircraft until the final accident report has been issued.

These three (3) attached lists should be consulted by anyone considering purchasing any accident damaged aircraft or components.

Moreover, Eurocopter reminds everyone that for obvious safety reasons, it is prohibited to reuse parts or assemblies which have been involved in an accident, without formal technical approval from Eurocopter Technical Support Directorate.
