The Certification Programme (CP) is an agreement between the applicant and DASA as to what certification activities must be completed in order for DASA to issue a Military Type Certificate or approval of a major change (including Military Supplemental Type Certificate).
Compliance demonstration comprises all the activities required to demonstrate that the product (or change to product), part or appliance complies with the requirements in the certification basis using the agreed means of compliance documented in the certification programme.
Military Supplemental Type Certificates (MSTCs) are a means for the approval of a major change to a product’s type design. The application and certification process is the same as for any other major change.
Under DASR 21, some approval holders are required to monitor in-service usage of their product, change to product, repair design, part or appliance in order to detect deficiencies that have resulted, or could result in an unsafe condition.
An Airworthiness Directive (AD) is a document mandating actions to be performed on an aircraft in a specific timeframe to restore an acceptable level of safety, when evidence shows that the level of safety level may otherwise be compromised.
A Military Design Organisation Approval is awarded to organisations that are eligible and successfully demonstrate to DASA that their design assurance system can safely design products, changes to products or repairs that comply with the applicable type certification basis.
When it is not reasonably practicable to restore the validity of a Military Certificate of Airworthiness through the use of approved data or by deferring a defect, a Military Permit to Fly is required in lieu.
