Another issue with the Boeing 737 has been identified.

Another issue with the Boeing 737 has been identified.

The FAA has issued a warning regarding potentially faulty components in the emergency oxygen supply.

The US Federal Aviation Administration (FAA) has mandated inspections for over 2,500 Boeing 737 aircraft due to potential issues with emergency oxygen generators. According to the FAA's Airworthiness Directive issued on Monday, Boeing identified a flaw in the retention straps of these generators that could impair their functionality during cabin depressurization.

The directive applies to approximately 2,600 Boeing 737 Max and Next Generation models. Airlines have been given between 120 and 150 days to complete inspections and perform necessary corrective actions. Boeing discovered that under certain conditions, the straps could shift up to 1.9 centimeters due to a faulty adhesive introduced in 2019. Boeing has reverted to the original adhesive for new deliveries to ensure secure attachment.

While Boeing initially recommended visual inspections in a memo to airlines on June 17, the FAA directive now mandates these inspections as a legal requirement. Airlines must inspect each oxygen generator and replace any defective straps. A typical Boeing 737 carries 61 oxygen generators, each with two straps, although configurations may vary among airlines.

This directive follows Boeing's recent $243.6 million fine for failing to comply with terms of a 2021 settlement related to issues with the 737 Max autopilot system. As part of the settlement, Boeing agreed to invest at least $455 million over the next three years to enhance safety and compliance measures and will undergo three years of probation under a government-appointed monitor.
