A UPS plane crash that killed 15 people last year might have been prevented if an original inspection schedule hadn't been relaxed, but mechanics didn't get a close look at the parts that should have kept an engine from flying off its wing because federal regulators allowed Boeing to recommend checking them less frequently, according to testimony Wednesday.
The National Transportation Safety Board's questions also drew out that Boeing relied on older data when it asked to extend the inspection schedule in 2015, and didn't seem to account for seven instances on other planes of the same model when the key engine mount parts were failing. The Federal Aviation Administration, for its part, approved the request after a month's review without seeking more information.
