Regulatory Response
Concerned by these developments, Maria Cantwell, chair of the Senate Committee on Commerce, Science and Transportation, along with Tammy Duckworth, chair of its aviation safety subcommittee, called on the Federal Aviation Administration (FAA) to reject Boeing’s request.
Subsequently, Boeing decided to withdraw the request. In a written statement, the company emphasized its dedication to transparency, listening to stakeholders, and taking measures to enhance safety and quality.
Implications on Existing Models
It is worth noting that the safety standard related to an anti-icing system not only impacts the new 737 Max model but also affects other currently operational 737 Max aircraft.
Last year, federal officials stated that Boeing was actively working on resolving the issue with the Max planes currently in service. In the interim, regulators advised pilots to exercise caution when utilizing the de-icing system under dry conditions due to the potential for high temperatures around the engines, which could result in parts of the housing detaching and striking the aircraft, including the possibility of windows being damaged and rapid decompression occurring.
Initially, the company intended to deliver its smaller Max 7 model, with pilots following the guidelines provided to Max 8 and Max 9 pilots. However, this plan has been disrupted due to safety concerns.
Reactions from Airlines and Lawmakers
Senator Cantwell expressed relief at Boeing’s decision, stating in an emailed statement on Monday night that this development is positive news.
In recent times, the FAA approved the inspection and maintenance procedures to allow the planes to resume operations. Consequently, Alaska Airlines and United Airlines, the only two US carriers operating Max 9s, have begun reintroducing them into service over the past few days.
Meanwhile, Southwest Airlines, the primary customer for the Max 7, announced last week that it has removed the model from its fleet plans until Boeing completes the necessary certifications in collaboration with the FAA.
Background
The FAA confirmed last year that it had not received any reports of overheating incidents on Max flights. Nevertheless, as the risk was identified during a test flight and its potential severity, the organization requested pilots to exercise caution. It should be noted that two crashes involving Max planes occurred in 2018 and 2019, resulting in the loss of 346 lives.
Moreover, in recent times, manufacturing flaws have disrupted Max deliveries. Last month, the company instructed airlines to inspect the planes for potential loose bolts in the rudder-control system. In response to these challenges, Boeing’s CEO expressed remorse, acknowledging the disappointment and frustration experienced by customers, some of whom have faced unwarranted public criticism.
