The thorough examination of Boeing’s safety procedures is expected to take three months, according to the FAA.

On Friday, the Federal Aviation Administration (FAA) formally announced its intention to begin a thorough examination of Boeing’s safety processes and procedures, which is a significant milestone.

The FAA stated in a release that the investigation will concentrate on important facets of Boeing’s safety procedures, including reaction speed, the calibre of the risk assessment, resource allocation, and compliance with legal requirements and FAA policy.

The thorough examination of Boeing’s safety procedures is expected to take three months, according to the FAA.

This investigation follows a string of high-profile technical accidents, such as the concerning airborne door plug issue on Alaska Airlines Flight 1282 in January that required the Boeing 737-9 MAX to make an emergency landing, according to The Hill.

A March FAA audit uncovered multiple compliance issues within Boeing’s manufacturing operations, specifically in process control, parts handling and storage, and product control. FAA Administrator Michael Whitaker recently testified before the Senate, shedding light on Boeing’s shortcomings. Earlier this year, the Justice Department launched a criminal investigation into Boeing’s record-keeping practices after the company revealed it couldn’t locate records related to factory work on the panel, raising concerns about compliance.

Sens. Elizabeth Warren (D-Mass.) and Richard Blumenthal (D-Conn.) expressed concern that the Justice Department should hold Boeing executives accountable for safety issues, and an agency memo revealed that Boeing failed to adequately train its employees and conduct thorough quality inspections. In the meantime, 33,000 machinists at Boeing have been on strike since September 13 in protest of their pay and the reinstatement of their pensions, highlighting the ongoing tensions between the company and its workforce.
