"There is a potential conflict of interest," said Todd Curtis, a former Boeing Co. safety engineer and creator of airsafe.com, a website that focuses on airline safety. "They (the FAA) don't have the money to do all of the oversight. It's a question of being practical."

The FAA's oversight duties are coming under greater scrutiny after deadly crashes involving Boeing 737 Max jets operated by airlines in Ethiopia and Indonesia, killing a total of 346 people. The U.S. was nearly alone in allowing the planes to keep flying until it relented on Wednesday after getting satellite evidence showing the crashes may be linked.
