Only OEM-traceable parts from Airbus Helicopters will be accepted, and no substitute or alternate parts will be considered. All parts must be FAA-approved and accompanied by a Certificate of Conformance. The government believes Airbus Helicopters is the only known source, but other responsible sources with the required capabilities may submit quotations.
