• 521.152 (1) Subject to section 521.153, no person shall undertake a change to the type design of an aeronautical product that has other than a negligible effect on the weight and centre-of-gravity limits, structural strength, performance, power plant operation, flight characteristics or other qualities affecting its airworthiness or environmental characteristics except in accordance with sections 521.155 to 521.160.
