Boeing Co. briefly suspended flights of its new, hot-selling 737 Max jetliner last month because of a possible flaw in an engine part produced by Arconic Inc., people familiar with the matter said.

The identity of the manufacturer wasn’t publicly disclosed after the issue grounded the high-profile jetliner days before its debut. The revelation is another blow to Arconic, which is facing possible lawsuits for supplying panels linked to the deadly London high-rise blaze earlier this month.
