Boeing CEO Muilenburg Issues Statement on Ethiopian Airlines Flight 302 Accident Investigation

CHICAGO, March 17, 2019 /PRNewswire/ — Boeing Chairman, President and CEO Dennis Muilenburg issued the following statement regarding the report from Ethiopian Transport Minister Dagmawit Moges today.

First and foremost, our deepest sympathies are with the families and loved ones of those onboard Ethiopian Airlines Flight 302.

Boeing continues to support the investigation, and is working with the authorities to evaluate new information as it becomes available. Safety is our highest priority as we design, build and support our airplanes. As part of our standard practice following any accident, we examine our aircraft design and operation, and when appropriate, institute product updates to further improve safety. While investigators continue to work to establish definitive conclusions, Boeing is finalizing its development of a previously-announced software update and pilot training revision that will address the MCAS flight control law’s behavior in response to erroneous sensor inputs. We also continue to provide technical assistance at the request of and under the direction of the National Transportation Safety Board, the U.S. Accredited Representative working with Ethiopian investigators.

In accordance with international protocol, all inquiries about the ongoing accident investigation must be directed to the investigating authorities.

Lost Tool Found in Qantas A380 After 34 Flights

An Australian Transportation Safety Bureau (ATSB) investigation recently revealed that a Qantas A380 operated 34 flights with a 1.25-meter nylon tool lodged in one of its engines.

This turning tool, used during borescope inspections to rotate the intermediate-pressure compressor, was left behind during scheduled maintenance at Los Angeles on December 6, 2023. It remained inside the engine until it was discovered by maintenance staff during a subsequent check at Los Angeles on January 1, 2024.

The ATSB report highlights two critical lapses. First, maintenance engineers failed to notice the tool during final checks for foreign objects after the borescope inspection. Second, the lost tool procedure was not activated when the tool was identified as missing.

The certifying engineer ultimately cleared the aircraft for service without accounting for the misplaced tool. During the time qantas films the tool was inside, the A380 completed 34 flight cycles, accumulating nearly 294 hours without any noticeable effect on engine performance.

Although the tool was deformed by high-energy airflow within the engine, there was no reported damage to the engine itself. ATSB Chief Commissioner Angus Mitchell commented.

“This incident underscores the importance of following established maintenance protocols. Engineers missed the tool during foreign object checks, and the required lost tool procedure wasn’t started after realizing the tool was missing.”

Following the investigation, the airline issued a safety directive, urging all engineering and tool storage teams to adhere strictly to these protocols to prevent similar incidents in the future.

A qantas spokesperson stated, “While the tool didn’t impact engine performance, we take this incident very seriously. It is critical to follow the correct lost tool procedures.”
