Delta replaces engines on more than 300 planes after toxic fume incidents

According to reports, Delta Air Lines replaces certain engines on more than 300 Airbus planes after the contamination of toxic smoke events contaminated cabin and sick crew members and passengers.

The airline has been changing small engines behind the aircraft since 2022 – auxiliary power units (APUs). Wall Street Journal Thursday reported.

When the main motors do not work, the units provide electric and cabin air and do not provide push for flight. Delta says that the study in the A320 jets is now about 90%.

Incorrect APUs, even when units do not work potentially, to allow toxic fumes and odors to spread along the cabin, can leak oil into the airflow system.

Airbus has accepted APU design as a leading factor in these events, but other engines on the plane can leak oil.

Toxic weather events for Delta and other US carriers have increased in recent years, especially in Airbus 320 family jets Magazine reported At the beginning of this month. The smoke caused brain injuries and other health problems between crew members and passengers, and led to other health problems. Some pilots even needed oxygen masks.

A Jetblue flight officer developed a traumatic brain damage that selected toxic smoke he said he smelled “dirty feet” on his way to Porto Riko.

When Florence Chesson asked if his colleague asked if he smelled something, he felt a drug after taking a deep breath. “I felt flashy,” he said to the magazine. “I remember being very repetitive, ‘What happened to me? What happened to me?’

In February, a boeing 717 filled with thick white smoke spilled out of holes. Later, an investigation found too much oil leaking from one of the engines and left the reservoir almost empty.

Meanwhile, a lawsuit filed by three former Jetblue flight officials on September 3 accuses Honeywell, the airline, Airbus and APU supplier, to allow harmful fumes to leak leakage between 2022 and 2024, as the magazine reported.

Case, tremors, heart palpitations and memory problems, including permanent health effects that cause exposure. In a 2022 incident, a child had a nosebleed and four crew members appeared to the hospital.

Not every event has been reported and the airlines use different standards to warn the Federal Aviation Administration.

Companies called in the case have not yet responded to the public. Fox News reached Jetblue for Digital comments.

Industry data shows that it is difficult to know how widespread the problem is because not every event is reported and the airlines use different standards to warn the Federal Aviation Administration.

Internal records have shown that manufacturers and regulators have knowledge about the seal problems in the APUs for decades. Honeywell and Pratt & Whitney, two of the largest suppliers, as Journal reported, met with A320 family models with seals designed to prevent oil from entering the air source.

Companies have made more than one correction over the years and made another update in which Honeywell 2023 said it would improve the passenger experience by reducing odor events.

A similar version of Honeywell’s Apu is also used in Boeing’s 737 Jets family. Meanwhile, American Airlines began to raise Honeywell Apu Seals in April 2023.

Honeywell and Pratt & Whitney did not comment on the reporting of the magazine.

Experts may reduce the risk of leakage, changing the old APUs, but does not solve the problem completely. The main engines of the aircraft and the main engines pumping the cabinet in “bleeding air” can also leak oil.

Airbus found that most of the smoke events related to APU are caused by oil or liquids entering the air intake.

The recommended long -term correction involves the transport of the input to the top of the aircraft and will reduce the “odor” events by 85%, but will only be made on new aircraft.

Fox News reached Delta and Airbus for Digital comments.

Delta said that the smoke events were rare, but they took them seriously.

“Delta has no additional interpretation or guidance, except for repeating that security has come first,” Delta, “Delta,” Delta, “Delta said to Fox News Digital.

Airbus said that the plane meets the regulatory requirements and continues to work with airlines and organizers to “improve their planes and provide the best cabin environment possible for passengers and crew.”
