NTSB: Systemic Failures Caused Alaska Airlines Door Plug Incident

NTSB Investigation Findings

• 🔍 The National Transportation Safety Board (NTSB) investigated the January 2024 incident where a door plug detached from a Boeing 737 Max during an Alaska Airlines flight.
• ⚠️ The investigation revealed systemic production issues at Boeing, including failures in training, oversight, and documentation.
• 🔩 Key findings indicate that bolts were removed and never replaced during the repair of the door panel.

Production and Repair Process Failures

• 🛠️ The fuselage was delivered with rivets that were not installed correctly, requiring the door panel to be removed for repair.
• 🧑‍🔧 The team responsible for removing the door panel had limited experience and was not specifically trained for that process.
• 📄 Crucially, the paperwork documenting the door removal was not completed, which would have prompted an inspection to identify the missing bolts.

Consequences and Oversight Issues

• ✈️ The plane departed from the factory without the necessary bolts reinstalled, leading to the door plug flying off after 154 flights.
• 🎯 The NTSB concluded that had just one bolt been installed, the door panel would have remained secure.
• 📊 The NTSB also identified problems with the FAA's oversight of Boeing, noting a lack of holistic review of recurring issues.
• 📉 The FAA's record-keeping only went back five years, preventing a full view of systemic problems.
