The Ministry of Transport in the United States (a point)
The Inspector General Office (Oig) started a review of the Federal Aviation Administration (FAA) and its actions in response to two air quality incidents in the cab in 2023.
The two incidents, who participated in the South West air plane Boeing 737 MAX 8, were not produced, that is, an immediate safety procedure after the CARB Correction Review Council decided not to recommend that temporary changes to take off.
FAA audit
In a note on April 16, Oig Dot informed that she would be subject to scrutiny FAA
Procedures in the processing of risk from pregnancy reduction devices (LRD) that are activated during bird strikes on CFM International Leap-1B engines, which operate exclusively Boeing 737 Max
Aircraft family.
According to Oig, the goal of scrutiny is to assess the actions of the organizer in response to CaQes, including when poisonous smoke and fumes enter into the cockpit or cabin of the plane when it activates LRDS. The office informed that the audit will start in April and include visits to the FAA offices that participated in the decision -making process related to LRDS.
In November 2024, FAA FLYING SIMPLE told November 26, 2024, carbohydrates held a meeting to discuss the issues surrounding LRDS on Leap-1BS, which led to smoke entering the cabin and/or cockpit. During the meeting, the Board of Directors discussed many internal Safety recommendations.
“Based on available data, carbohydrates specify that the problem does not guarantee immediate action, and FAA will follow the process of setting the standard rules for processing them. The Federal Aviation Administration will make a continuous notification of the sides of the international community aircraft (Canic) about the new information provided by Boeing to aircraft operators with Leap-1B engines. New information contains improved instructions directed by flying crews more quickly to the appropriate procedures when they suffer from abnormal indicators of the engine. “
Birds
Oig detailed that in March 2023 and December 2023, two separate events caused the bird strike 737 Max 8
Aircraft, causing smoke and toxic fumes to enter the plane, endangered life. These strikes break the plane engine blades’, which stimulates LRDS, a design feature that reduces unbalanced vibrations caused by engine damage to help prevent more problems.
When LRDS was activated during CaQes, which is a specific term IATA as simple or main events that include scent or air pollution inside the plane, “A large amount of engine oil flowed to the hot section of the engine, causing smoke and toxic fumes to enter the cockpit or cabin through environmental pressure and aircraft systems.”
In December 2023, LRD was activated in the left Leap-1B engine, which, according to Oig, was worrying since SMKE entered the cockpit and the flight crew can be unable. In March 2023, LRD was activated in the right side engine, and smoke is sent to the cabin, as stated in the office statement.

In a statement of simple aviation in November 2024, CFM International,
“LRDS has been used in the industry for more than 20 years and has been designed as designed. The company was working with the AAA (Essa),
And Boeing to determine any learning from “The last events.”
According to CFM International, LRDS is an installed technology that meets all the requirements for issuing certificates and works as designed to prevent the risks to the plane, which repeats that the LEAP engine, which also occupies the A320neo aircraft family as the requirements of Leap-1A, meets the requirements of FAA and EAAA. However, the speaker noticed that “Birds in these incidents have greatly exceeded the size and weight of the criteria for swallowing organizational birds,” However, engines are still performing as designed during the two accidents.
