QUAKE COPING: No aerospace suppliers to Mitsubishi Heavy Industries have reported production difficulties from either earthquake damage or a shortage of electricity, a spokesman for the company says. Mitsubishi, itself located far from the epicenter of Japan’s March 11 earthquake that knocked out power stations, has also had no trouble as a result of damage or electricity stoppages, the spokesman says.

BEIJING — Component supplies to Fuji Heavy Industries and deliveries from the company are assured until the end of April, as earthquake-hit suppliers progressively resume operations or dispatch parts from stocks. Fuji, one of Japan’s four big aerospace companies and a key partner in the Boeing 787 program, is improvising to mitigate the effects of power stoppages, which it said last week were a bigger problem than physical damage to suppliers’ factories.

BEIJING — Precision machine tool builder Mitsui Seiki Kogyo says it is now operating almost normally, having lost only about two days’ production from the March 11 earthquake. The company, a crucial supplier to the global aerospace industry, says it is largely coping with electricity stoppages. Perhaps most importantly, it says that its machine tools in service with Japanese customers rode out the earthquake and can work to specification.
