Which Plane Has the Worst Safety Record? Understanding Aircraft Safety Ratings

When it comes to air travel, safety is paramount, and passengers often seek reassurance about the safety records of different aircraft models. While all commercial airplanes undergo rigorous testing and certification processes to ensure their safety, some models have experienced more incidents than others. Let’s explore the concept of aircraft safety records and examine factors that may contribute to a plane being perceived as having a poor safety record.

Understanding Aircraft Safety Records

Safety Ratings:

  • Aircraft safety records are typically measured based on accident rates, incidents, and fatalities per million flight hours.
  • Regulatory agencies, aviation authorities, and independent organizations compile data on aircraft safety performance to assess their overall safety records.

Contributing Factors:

  • Factors that may influence an aircraft’s safety record include its design, manufacturing quality, maintenance procedures, operational environment, and pilot training.
  • External factors such as weather conditions, air traffic control issues, and human error can also impact aircraft safety.

Aircraft with Poor Safety Records

Boeing 737 MAX:

  • The Boeing 737 MAX gained notoriety following two fatal accidents involving Lion Air Flight 610 in October 2018 and Ethiopian Airlines Flight 302 in March 2019.
  • The accidents, both attributed to a faulty flight control system known as the Maneuvering Characteristics Augmentation System (MCAS), resulted in the grounding of the 737 MAX fleet worldwide and a significant overhaul of Boeing’s safety procedures.

McDonnell Douglas DC-10:

  • The McDonnell Douglas DC-10 experienced several high-profile accidents in the 1970s and 1980s, including the crash of American Airlines Flight 191 in 1979 and Turkish Airlines Flight 981 in 1974.
  • Design flaws, including issues with the cargo door and hydraulic system, contributed to some of the accidents involving the DC-10.

Airbus A320neo:

  • While the Airbus A320neo has not experienced fatal accidents, it has faced scrutiny due to safety concerns related to its Pratt & Whitney PW1100G engines.
  • Engine failures and in-flight shutdowns prompted airlines to ground A320neo aircraft temporarily and implement inspections and modifications to address the issues.


While certain aircraft models may have experienced incidents or accidents in the past, it’s essential to consider the broader context and contributing factors when assessing their safety records. Manufacturers, regulatory authorities, and airlines continually work to address safety issues, improve aircraft design, enhance maintenance procedures, and prioritize pilot training to ensure the safety of air travel. Passengers can take comfort in knowing that commercial aviation remains one of the safest modes of transportation, with stringent safety standards and protocols in place to mitigate risks and ensure the well-being of passengers and crew.
