WASHINGTON (NewsNation Now) — A House committee issued a report Wednesday questioning whether Boeing and government regulators have recognized the problems that caused two deadly 737 Max jet crashes and whether either will be willing to make significant changes to fix them.

Staff members from the Democrat-controlled Transportation Committee blamed the crashes that killed 346 people on the “horrific culmination” of failed government oversight, design flaws and a lack of action at Boeing despite knowing about problems.

The committee identified many deficiencies in the Federal Aviation Administration approval process for new jetliners. But both the agency and Boeing have said certification of the Max complied with FAA regulations, the 246-page report said.

“The fact that a compliant airplane suffered from two deadly crashes in less than five months is clear evidence that the current regulatory system is fundamentally flawed and needs to be repaired,” the staff wrote in the report released early Wednesday.

The Senate Commerce Committee on Wednesday could make changes to a bipartisan bill introduced in June giving the FAA more control over picking company employees who sign off on safety decisions. One improvement may be that a plane with significant changes from previous models would need more FAA review.

The House report stems from an 18-month investigation into the October 2018 crash of Lion Air flight 610 in Indonesia and the crash of Ethiopian Airlines flight 302 in March of 2019. The Max was grounded worldwide shortly after the Ethiopia crash. Regulators are testing planes with revamped flight control software, and Boeing hopes to get the Max flying again late this year or early in 2021.

This is a developing story.
