This is incorrect with regard to certified engines or parts.
All certified aircraft parts with a valid certificate of airworthiness ( form one or 8130 or equivalent) are duty free. This is a WTO ruling recognised all around the world.
Pre and post the UK/EU trade agreement nothing has changed and nothing would have even without a trade agreement.
In regard to Lycoming engines, historically a large number of engines failing to reach TBO or high time was due to corrosion. This did lead to camshaft and tappet failure in many cases. Since the introduction of the Lycoming roller tappet and camshaft, these premature failures have virtually disappeared completely.
