Boeing Co. said it’s continuing to investigate quality issues affecting its 737 Max aircraft, after a report on new inspections tied to a recent production flaw sent the shares lower on Friday.

Inspections of some Max 8 models will now include hand-drilled holes on a component that helps maintain aircraft cabin pressure, The Air Current reported earlier. A quality probe tied to the production flaw is ongoing, Boeing said in an email.
