In response to reduced demand for its aircraft engines, Teledyne Continental Motors has shut down its production line for this week. TCM will make other cost-cutting adjustments in the coming months. Sales, shipping and customer-support personnel remain on the job during the shutdown. Further cuts will involve four-day work weeks for salaried personnel starting with the return to work next week; and week-long breaks for the Thanksgiving and Christmas holidays. Another production shutdown is scheduled for Jan. 4-9 next year. Part of the low-demand business strategy at TCM includes rebuilding its backlog of engines and parts "to a level that supports efficient factory operations," according to the company.
