No end to the revelations about Boeing’s 737 Max planes, after the two fatal plane crashes – in 2018 by Lion Air with 189 people on board and in 2019 by Ethiopian Airlines with 257 people on board – and the detachment of a door that fell from a brand new 737 Max plane against the duration of the flight operated by Alaska Airlines.

The Senate launched an investigation into aircraft safety in January 2024, and since then alarming conclusions have been coming to light.

The latest revelations come from security investigators who made “urgent” recommendations to Boeing and the Federal Aviation Administration yesterday.

According to the AP, the experts found that pedals pilots use to steer 737 Max jets onto runways and takeoffs may ‘stick’ from moisture leaking into the rudder system, which can freeze and jam the pedals.

Collins Aerospace, a Boeing supplier, found that a sealed bearing it had been incorrectly assembled on the rudder actuators that pilots use to stay centered on the runway after landing.

The company told Boeing that the faulty part affected it at least 353 actuators installed on some Max jets and earlier 737s;according to the NTSB.

The National Transportation Safety Board (NTSB) issued the recommendations Thursday following its investigation into an incident earlier this year involving a United Airlines plane.

The FAA said United is the only U.S. airline affected by the recommendations and believes the jam-prone components are no longer in use.

At the same time, about 30,000 workers at Boeing’s factories in Seattle and Portland, where the 737 MAX and other jets are made, have decided to go on strike as the company struggles with schedules, late deliveries and mounting debt.

In August 2024, two workers were killed and a third injured when a wheel exploded while being removed from a Boeing aircraft at Delta Air Lines’ aircraft maintenance and repair facility at Hartfield-Jackson International Airport in Atlanta.
