• It states that subpart B establishes the procedure for issuing type certificates for products and restricted type certificates for aircraft, and establishes the rights and obligations of the applicants for, and holders of, those certificates
•It states that the DGCA shall prescribe special detailed technical specifications, named special conditions, for a product, if the related airworthiness code does not contain adequate or appropriate safety standards for the product namely: -
1. The product has novel or unusual design features relative to the design practices on which the applicable airworthiness code is based.
2. The intended use of the product is unconventional.
3. Experience with other similar products in service or products having similar design features, has shown that unsafe conditions may develop.
• It further states that the special conditions contain such safety standards as DGCA finds necessary to establish a level of safety equivalent to that established in the applicable airworthiness code.
• It states that Any natural or legal person proposing to change a product shall apply for a new type certificate if DGCA finds that the change in design, power, thrust, or mass is so extensive that a substantially complete investigation of compliance with the applicable type certification basis is required.
•All relevant design information, drawings, and test reports, including inspection records for the product tested, shall be held by the type-certificate or restricted type-certificate holder at the disposal of DGCA and shall be retained in order to provide the information necessary to ensure the continued airworthiness and compliance with applicable environmental protection requirements of the product.
