DGCA (Directorate General of Civil Aviation) considers the aircraft that I build as a construction from the plans / lot material, even if it is well prepared by the manufacturer.
The certification scheme is referred CNRA (restricted certificate of airworthiness of aircraft).
Certification is initiated by the creation of a file submitted to the OSAC (Organization for the Safety of Civil Aviation).
CNRA prohibits the receipt of entire parts preassembled kit if the manufacturer does not perform at least 50% of the construction of the aircraft.
OSAC just do 3 inspections instead of construction:
– Inspect the wing spars (for approval aerobatics)
– Inspect the wings just before their closures
– Inspect the aircraft when it is finished, to allow flight testing, just before the final certification.
Then, the technical inspection is done every 3 years for builders who built their plane (all other years).
