This bombshell discovery, coming on the heels of a 19-day emergency grounding of all Max 9s, reignited concerns surrounding Boeing's quality control practices. The absence of these bolts, as highlighted by the report, raised serious questions about the safety and integrity of the aircraft.

Crucial Evidence Unveiled

The report delved deeper into the investigation, shedding light on key pieces of evidence that pointed to the absence of the bolts. A significant breakthrough came in the form of a picture captured in a text message exchanged between employees, showcasing the missing bolts during maintenance work on the aircraft.

Further analysis from a laboratory disassembly of the door plug provided compelling evidence that the bolts were indeed missing prior to the flight. The meticulous examination revealed a lack of damage where the bolts should have been, solidifying the conclusion that the crucial components were nowhere to be found.

Implications and Industry Response

The repercussions of this alarming discovery reverberated across the aviation sector, prompting immediate action from Boeing. The company, in a bid to address the issue and prevent recurrence, acknowledged its responsibility for the blowout and vowed to enhance its manufacturing processes.

Amid escalating scrutiny, both Alaska Airlines and United Airlines reported findings of loose bolts in their fleets post the incident, signaling a broader concern beyond the single occurrence. The incident underscored the critical need for stringent quality control measures and oversight in aircraft production.
