The Federal Aviation Administration's superseding airworthiness directive "was prompted by a report of a crack found in a front spar lower chord," it said in the Federal Register notice.
Errors in the earlier directive also "introduced a new unsafe condition related to the application of certain fastener cap seals," it said.
Although Boeing intends to revise the bulletin, the FAA issued the new directive as "this work will take longer to accomplish than the risk to public safety allows," the agency said.
A Boeing spokesperson said it fully supported the FAA's rule, “which is consistent with guidance we have shared with operators previously.”The FAA did not immediately provide comment.
