Southwest Airlines Boeing 737 Max sustains Alot Of Damage In Dutch Roll incident
The recent Dutch Roll incident involving a Southwest Airlines Boeing 737 Max has raised concerns within the aviation industry.
What Happened?
- At almost 38,000 feet, the Boeing 737 Max experienced a rare phenomenon known as a Dutch roll.
- During this incident, the aircraft’s tail began to yaw or wag left and right, while its wings rocked side to side.
- Dutch roll is a potentially dangerous lateral asymmetric movement, also inspired by the movements of ice skaters.
- Despite the challenging situation, the skilled pilots managed to regain control.
- The plane landed safely in Oakland, and fortunately, no injuries were reported among the 175 passengers and six crew members.
What Is a Dutch Roll?
Dutch roll is a potentially dangerous lateral motion that mimics the movements of ice skaters.
- Cause: It occurs when an aircraft experiences a combination of yawing motion (tail sliding) and rolling motion (wingtip-to-wingtip rocking).
- Recovery: Pilots are trained to counteract Dutch roll, and modern airliners are also equipped with a system called a yaw damper to prevent it.
Damage and Investigation
- The 737 Max sustained substantial damage during the incident.
- The Federal Aviation Administration (FAA) is working with Boeing and also the National Transportation Safety Board (NTSB) to investigate the cause.
- A preliminary report indicated that the aircraft experienced the roll, regained control, and also post-flight inspection revealed damage to the standby power-control unit (PCU).
- Federal aviation regulations require that a Dutch roll occurring below the allowed speed must be positively damped with controls free and controllable also using normal primary controls without exceptional pilot skill.
- Other airlines have not reported similar issues, and Boeing is cooperating with the investigation.
Safety Regulations
- Federal aviation regulations require that a Dutch roll occurring below the allowed speed must be positively damped with controls free.
- Training: Enhanced training for pilots on handling Dutch Roll scenarios.
- Also Software Updates: Boeing continues to improve the MCAS system.
- Industry Collaboration: Airlines and manufacturers share insights to prevent similar incidents.
- The yaw dampener in most aircraft should correct the lateral movement.
Boeing’s Ongoing Investigations
- Boeing is undergoing several investigations, including one by the Justice Department, after a panel blew out on a 737 Max 9 plane in January.
- The company emphasizes safety practices, also including using machine-learning algorithms to spot potential faults.
The aircraft sustained structural damage, affecting its airframe, control surfaces, and systems. Southwest Airlines temporarily grounded the affected aircraft for inspection and repairs. Authorities are conducting a thorough investigation to determine the root cause.
