The Qantas captain and co-pilot were temporarily “incapacitated” and “out of breath” during the horrific Mayday incident.
The Qantas captain and co-pilot were temporarily “incapacitated” and “out of breath” during the horrific Mayday incident three years ago, a new aviation safety report said.
A report by the Australian Transport Safety Bureau, released Thursday, revealed disturbing details about the Express Freighters Australia aircraft traveling from Brisbane to Melbourne on August 15, 2018.
When the warning light flashed, the crew wore an oxygen mask and the aircraft began an emergency descent.
However, in the first part of the descent, the Qantas Boeing 737-376 captain was “temporarily incapacitated” and “out of breath” in response to an increase in the supply of respiratory oxygen from the mask. Is reported. ..
Later, May Day was declared by the co-pilot, also known as the co-pilot, and the aircraft began a detour to Canberra Airport.
“The first police officer was aware that he had previously talked about feeling sick and observed the captain falling forward, nauseating and out of breath,” said the ATSB.
“The first officer remembered checking the captain during this episode, but did not receive a response.”
After the captain recovered, the first officer suffered from “neutralization symptoms consistent with hyperventilation.”
When the captain’s radio arrived in Canberra, where the aircraft landed safely, he called for air traffic control to request the attendance of emergency services.
The report said both pilots were incapacitated at the same time “without points”.
Investigation has determined that the intermittent flicker of the master warning light and overheat indicator is most likely due to an electrical failure of the overheat detection system on the right wing body.
“During the descent, the captain chose an emergency stream of oxygen masks, ingested gaseous oxygen and temporarily disabled it,” the report read.
“The crew in flight performed an appropriate abnormal checklist, but failed to correct the signs of overheating due to a failure of the wing overheat detection system,” the report read.
“An additional failure with the shutoff valve in the aircraft’s pressurization system prevented the right wing body from shutting down the pressure duct.
“This caused the crew to troubleshoot further, during which time the air supply in the cabin was reduced.
“In addition to the higher than normal cabin leak rate, the reduced airflow also reduced the cabin pressure.”
After landing, both the captain and the co-pilot were taken to the hospital by ambulance for medical evaluation.
Post-occurrence medical examination and evaluation did not confirm the lasting effects of flight.
During post-accident inspections, Cantus engineers commented on “various maintainability” of the aircraft’s cabin drain valves, fuselage door seals, and auxiliary power unit duct bellows seals that affect the ability of the aircraft to hold pressure. I have identified the problem.
According to the report, Qantas advised ATSB to incorporate maintenance changes to avoid similar incidents in the future.
In a statement to NCA NewsWire, a Qantas spokesperson said:
“These freighters were maintained according to the manufacturer’s requirements, but then performed additional checks on the maintenance program.”
