Federal aviation officials ordered airlines to inspect all of four types of Boeing airliners built in the last eight years after wiring mix-ups were found on four more planes. In its most far-reaching order to date on the possibility of cross-wiring and cross-plumbing in airline safety systems, the Federal Aviation Administration gave airlines 25 days to complete the testing of both engine and cargo hold safety systems in 741 aircraft. The inspections were ordered for Boeing 737s, Jumbo 747s, 757s and 767s.
