Boeing Co. /zigman2/quotes/208579720/composite BA -1.76% said late Friday that by mid-April it will "temporarily" cut its 737 production rate to 42 planes a month from 52 planes to account for the ongoing halt in 737 Max deliveries. That will allow the company "to focus on software certification and returning the Max to flight," Boeing said in a statement. The 737 Max has been grounded worldwide after two 737 Max jets crashed within less than five months. There will be no layoffs in the 737 program and related production teams, and the company is working with customers and suppliers to mitigate any impact, Boeing said. In the same statement, the company said it asked its board of directors to form a committee to review policies and processes for the design and development of the airplanes it builds. Shares of Boeing fell 1.8% in the extended session Friday after ending the regular session down 1%. The stock gained nearly 3% for the week, however, as Wall Street cheered an initial report earlier in the week on the Ethiopia Air crash that found similarities between the March accident and the Lion Air crash in October. Boeing's software fix, expected to be installed in the next few weeks, would thus address the faulty system that contributed to both crashes.
