What is DOAS
  • DOAS is a means to recognize the Design Organization(DO) that has a well-defined Design Assurance System (DAS) for enabling the DOs to be an applicant/ holder of Military Type Certificate (MTC) for Air Systems and Type Approvals (TA) for Airborne Stores.
  • DOAS is not pre-requisite for bidding process or developments contracts.
  • DOAS approval is ‘Process Driven’ at par with International Practices.
Intent of DOAS
  • Capability of any firm to ‘Meet Airworthiness Certification Requirements’.
  • DOAS is a means for ‘Effective Engagement between Design organization & CEMILAC’.
  • Emphasis is on ‘Design Assurance Process’.
  • Required for firms Developing ‘Critical & Complex Products’ leading to Type Certification (Aircraft) and Type Approval (LRUs).
Scope of DOAS
  • Leverages on Industry driven accreditation process like AS9100, CMM and NADCAP approvals.
    • Third party accreditations are uniform, faster.
    • Enables firms to work for military aviation.
  • Emphasis is for Main Contractorsthat develop ‘Complex’ products like
    • Air systems (Aircrafts, Helicopters, Engines, Missiles).
    • Airborne Equipment (Flight & Mission Critical Systems and LRUs).
  • Not applicable for organization that develop ‘Modules, Components and Materials) that are part of Air System & Airborne Equipment.
  • Gives the flexibility to main contractor to select and integrate sub modules.
Prerequisites for DOAS
  • Should be AS9100 Approved
    • Ensures that Basic Development Processes are in place.
  • The firm should have robust ‘Design Assurance Process’
    • Establishment of an Airworthiness Group & Independent Monitoring Group.
    • Exclusive ‘Compliance Verification Engineers’ – Competent & specialized engineers for Independent Verification & Validation.
    • Rigorous Analysis and Review Processes.
    • Requisite Tools for analysis and Testing.
    • Stringent Configuration Management.

    • Design Assurance Process.
    • Organization Structure to that ensures Design Assurance Process.
Benefits of DOAS

For D&D Organizations

  • International Recognition
    • Once mutual recognitions are established with foreign airworthiness authorities, firms with DOA would have international status.
