The aftermath of two fatal crashes involving Boeing's 737 Max planes has shaken the US aviation industry, prompting new reflection on how planes get made and certified.

The fatal Lion Air and Ethiopian Airlines crashes that killed almost 360 people between them have shaken confidence in the US Federal Aviation Administration, leading to new scrutiny on how it allows manufactures to help certify their own planes and sparking federal investigations into its processes.

Christine Negroni, an air-safety specialist and the author of "The Crash Detectives," a book about aviation disasters, told Business Insider that Boeing is unlikely to get away "unscathed" as its safety processes come under scrutiny.

Any changes to how planes are made and certified would be in line with the aftermath of past disasters and flaws in aircraft design, which have resulted in permanent changes in how aircraft are made, flown, and regulated.

Negroni said "necessary havoc" comes as the aviation industry changes but that each disaster results in a greater understanding of how to make planes safer.
