The Federal Aviation Administration (FAA) recently conducted a 6-week audit of Boeing's 737 Max production process and found numerous issues. This audit was prompted by a concerning incident where a door panel blew out mid-air. During the audit, federal investigators discovered several alarming practices, such as mechanics using dish soap as a lubricant while checking the door seal and even using a hotel key card to inspect the door seals.
Boeing reportedly failed 33 out of 89 product audits, while its supplier, Spirit Aerosystems, failed 7 out of 13. This comes amidst a series of incidents involving Boeing planes, including an engine catching fire on a flight from Houston to Florida and a tire falling off a plane departing from San Francisco, which resulted in the tire crushing a car in an airport parking lot.
