We will explore the accident, the pilots' experience, and the aftermath, providing a comprehensive overview.

The Fateful Flight

On March 10, 2019, Ethiopian Airlines Flight 302, a Boeing 737 MAX 8, crashed shortly after takeoff from Addis Ababa, Ethiopia, killing all 157 people on board. The flight was headed to Nairobi, Kenya, and among the passengers were people from over 30 countries. The tragedy immediately raised concerns about the safety of the 737 MAX 8 aircraft, especially since a similar crash involving Lion Air had occurred just a few months prior.

Initial Moments After Takeoff

Right after takeoff, the pilots of Flight 302 encountered significant difficulties in controlling the aircraft. The plane began to experience erratic altitude fluctuations, making it challenging for the pilots to maintain a stable climb. This was not a typical situation, and the pilots quickly realized they were dealing with a serious problem.

Pilots' Struggle for Control

The pilots, Captain Yared Getachew and First Officer Ahmednur Mohammed, were highly experienced. Captain Yared had over 8,000 flight hours, and First Officer Ahmednur had around 200 hours. Despite their experience, they struggled to regain control of the aircraft. The plane's nose repeatedly pitched downwards, and the pilots fought to bring it back up, following emergency procedures and attempting to override the automated systems.

Emergency Signals and Communication

As the situation worsened, the pilots sent out distress signals to air traffic control, requesting permission to return to Addis Ababa. They communicated the difficulties they were facing in controlling the aircraft and the urgent need to land. However, the rapid descent and the plane's unstable condition made it impossible to make it back to the airport.

The Pilots: Captain Yared Getachew and First Officer Ahmednur Mohammed

Let's take a closer look at the pilots who were at the helm of Flight 302. Understanding their backgrounds and experience levels provides valuable context to the events that unfolded during the flight. Both Captain Yared Getachew and First Officer Ahmednur Mohammed faced an unprecedented challenge, and their actions in the cockpit have been closely analyzed in the aftermath of the crash.

Captain Yared Getachew

Captain Yared Getachew was a seasoned pilot with over 8,000 flight hours under his belt. He had extensive experience flying Boeing 737 aircraft and was considered a highly competent and skilled aviator. His leadership in the cockpit would have been crucial during the emergency. With his vast experience, he would have been well-versed in handling various flight scenarios and emergencies. His training would have prepared him to make critical decisions under pressure, and his expertise would have been invaluable in attempting to regain control of the aircraft.

First Officer Ahmednur Mohammed

First Officer Ahmednur Mohammed, while less experienced than Captain Yared, was a dedicated and trained pilot. He had accumulated around 200 flight hours. Although he was relatively new to flying, he had undergone rigorous training and was certified to operate the Boeing 737 MAX 8. As a first officer, he would have played a crucial role in assisting the captain, monitoring the aircraft's systems, and following emergency procedures. His contributions would have been essential in the cockpit as they worked together to address the challenges they faced.

The Role of MCAS

The investigation into the crash quickly focused on the Boeing 737 MAX's Maneuvering Characteristics Augmentation System (MCAS). This system was designed to prevent the plane from stalling by automatically pushing the nose down if it detected a high angle of attack. However, it was found that a faulty sensor could trigger MCAS even when the plane was not in danger of stalling, leading to a dangerous and unrecoverable situation.

How MCAS Works

MCAS uses inputs from angle of attack (AOA) sensors to determine if the aircraft is at risk of stalling. If the AOA is too high, MCAS activates and pushes the nose of the plane down to increase airspeed and prevent the stall. The system was intended to make the 737 MAX handle similarly to previous 737 models, despite its larger engines and different aerodynamic characteristics. However, the system's reliance on a single AOA sensor and its powerful ability to override pilot input proved to be critical flaws.

MCAS and the Ethiopian Airlines Crash

In the case of Flight 302, it is believed that a faulty AOA sensor triggered MCAS shortly after takeoff. This caused the system to repeatedly push the nose of the plane down, even though the aircraft was not in a stall condition. The pilots struggled to counteract the system, but MCAS continued to activate, making it nearly impossible for them to maintain control. Despite following emergency procedures and attempting to override the system, the pilots were unable to prevent the crash.

Boeing's Response and Software Updates

Following the Ethiopian Airlines crash and the earlier Lion Air crash, Boeing faced intense scrutiny over the design and implementation of MCAS. The company initially defended the system but eventually acknowledged its role in the accidents. Boeing developed a software update for MCAS that included several changes to improve its safety and reliability. These updates included using inputs from two AOA sensors instead of one, limiting the number of times MCAS could activate, and giving pilots more control to override the system.

The Aftermath and Investigations

The Ethiopian Airlines Flight 302 crash led to a global grounding of all Boeing 737 MAX aircraft. Investigations were launched by multiple agencies, including the Ethiopian Accident Investigation Bureau and the U.S. National Transportation Safety Board (NTSB). The investigations aimed to determine the exact cause of the crash and to identify any systemic issues that contributed to the accident.

Findings from the Investigations

The investigations revealed several critical factors that contributed to the crash. These included the faulty AOA sensor, the design of the MCAS system, and inadequate training for pilots on how to handle MCAS malfunctions. The investigations also highlighted a lack of communication between Boeing and the FAA regarding the risks associated with MCAS. The findings led to numerous recommendations for improving aircraft safety, pilot training, and regulatory oversight.

Boeing 737 MAX Grounding and Return to Service

The Boeing 737 MAX was grounded worldwide for nearly two years following the Ethiopian Airlines crash. During this time, Boeing worked to address the issues identified in the investigations and to implement the software updates and other changes required by regulators. The FAA eventually approved the 737 MAX to return to service in November 2020, after Boeing had made the necessary modifications and pilots had undergone additional training. Other countries followed suit, and the 737 MAX gradually returned to service around the world.
