The term "beyond economical repair" (abbreviated "BER") was used to refer to damage to an item extensive enough that the cost of repair significantly exceeded a given percentage (typically 80%) of its replacement value. In an alternate 2371, the crew of USS Voyager judged the shuttles Tyson and Shen Quo BER and cannibalized them to fix the Ali Qushji. (The Mysterious Case of Neelix's Lungs: "Factoring Primes")
