On July 24, 2023, a Delta Air Lines Boeing 767 encountered severe turbulence and hail shortly after departing from Milan’s Malpensa Airport. The flight, bound for John F. Kennedy International Airport, faced significant challenges due to inadequate review of available weather data, according to a report by Italian transportation investigators. This incident highlights the critical importance of thorough weather assessments in aviation safety.
Incident Overview
The aircraft quickly found itself in a hailstorm, resulting in extensive damage. Passengers reported terrifying experiences during the turbulence. One passenger, Steven Coury, described hearing loud banging noises, which increased anxiety on board. The plane suffered a cracked windshield and a 30-inch-wide hole in the nose, along with dents on the wings and engine damage.
Flight Path and Decisions
As the crew confronted the severe weather, their decision-making process was scrutinized. The pilots were unable to turn right due to the Alps and opted for a left turn, despite already experiencing damage. The first officer reported seeing a flash of light before a crack appeared on the windshield.
Emergency Landing
Due to the extent of the damage, the crew made an emergency landing in Rome. Passengers praised the crew’s handling of the situation, with Coury noting their exemplary efforts during the ordeal. He questioned why the flight was permitted to take off under such dangerous weather conditions.
Weather Data Negligence
- The investigation revealed that pilots and dispatchers did not utilize all available weather information.
- Important radar satellite images that could have indicated severe weather were not included in the pilots’ briefing.
- Air traffic control did not issue warnings about hail, and the pilots did not request these updates.
According to the report, Delta’s meteorology department had the capability to forecast the adverse weather using accessible satellite radar images. However, this assessment did not take place.
Following Actions by Delta Air Lines
In light of the incident, Delta has emphasized the need for improved thunderstorms and hail avoidance in its pilot communications. The airline has also initiated upgrades to the weather radar systems on some of its aircraft, reaffirming its commitment to passenger safety.
Delta expressed appreciation for the investigators’ efforts and reiterated its goal of maintaining the world’s safest air travel, despite these incidents being rare.
The flight involved twelve crew members, including eight cabin crew, and a total of 214 passengers. This event serves as a critical reminder of the importance of diligent weather monitoring in aviation.
