United Airlines Discovers Installation Issues

United Airlines (NASDAQ:UAL) has encountered a worrisome discovery during inspections of Boeing (NYSE:BA) 737 Max 9 planes. This revelation came to light after the Federal Aviation Administration ordered inspections following a disconcerting incident on an Alaska Airlines (NYSE:ALK) flight.

Raising Questions about Quality Controls

This finding by United Airlines has raised significant questions about the quality controls in place for the 737 Max 9, a critical variant of the Boeing-made jetliner.

Troubling Discoveries

As a result of preliminary inspections, United Airlines uncovered issues related to the installation of several panels. The carrier indicated that these problems are linked to the door plug, such as bolts requiring additional tightening.

Investigation into the Cause

The National Transportation Safety Board is currently investigating the incident that caused the door plug to rip away from the Alaska Airlines plane, leading to a rapid depressurization of the cabin. Notably, the discovery of the 63-pound plug in a schoolteacher’s yard further underscores the gravity of the situation.

FAA Approval and Boeing’s Response

The U.S. Federal Aviation Administration has approved the inspection steps for grounded 737 Max 9 jets, a crucial step in ensuring the planes can return to service. Boeing executives, on the other hand, have taken proactive measures, including the inspection of plugs on undelivered Max 9 jets at their factory, as well as at the Spirit AeroSystems’ (NYSE:SPR) plant.

Market Reaction

The market has reacted to these developments, with Boeing’s stock falling 8% and Spirit AeroSystems’ shares finishing 11% lower in regular trading on Monday. This underscores the potential impact of the situation on the aviation industry at large.
