WASHINGTON (Reuters) - Boeing said Wednesday it is making progress on developing a permanent solution to address an issue with the 737 MAX anti-ice system that can overheat and could cause an engine failure.

The planemaker in January withdrew a request it filed with the Federal Aviation Administration last year seeking an exemption from a safety standard for its forthcoming 737 MAX 7 over the issue, which pushed potential certification into 2025.
