Spare Parts

All functional parts of Rada products are kept for up to ten years from the date of final manufacture.
If during that period, our stock of a particular part is exhausted we will, as an alternative, provide an
equivalent new product or part at a price equating to the cost of repair to the old, bearing in mind the age
