DPO RESPONSIBILITY WHEN CONTRACTING ACTIVITIES
(a) A DPO, responsible for ensuring that the design of the ATM/ANS equipment complies with the applicable certification basis requirements or detailed specifications used for the declaration of design compliance, as applicable, should ensure that components designed, or tasks performed, by external parties are acceptable. To discharge this responsibility, the DPO should implement documented methods that ensure the compliance of the finished (ready to be delivered) ATM/ANS equipment, and that make use of these components or task results, prior to issuing the final EASA release form.
(b) As the responsibility for verification of compliance remains with the DPO, no specific qualification measures are required other than to pragmatically verify the capabilities of the external party, and to ensure that the required level of detail is met to enable the task results to be adequately verified.
(c) If a DPO subcontracts the compliance monitoring function to an external party that conducts the task, but does not hold its own DPO approval, then the same requirements for the qualification, nomination and documentation apply to the person who is nominated and indicated in the DPO handbook of the contracting DPO.
(d) Alternatively, if an organisation with a DPO approval obtains design substantiation data from a subcontractor that also holds a DPO approval, and the work that is conducted is within the approved scope of this subcontractor DPO, the subcontractor’s design data becomes acceptable when the contracting DPO has verified that the results adequately meet the needs of the ATM/ANS equipment under development. Additional formal compliance verification by the contracting DPO is not required if the person responsible for compliance verification of the contracted DPO signs and approves the document under its DPO approval.
ATM/ANS equipment design organizations (DPOs) must ensure external parties' work meets compliance standards before final release. DPOs verify subcontractor capabilities and task results. Subcontracting compliance monitoring requires equivalent qualification standards. Data from approved subcontractor DPOs is acceptable upon verification, potentially waiving further compliance checks if properly signed off.
