Boeing, the American multinational aerospace company, is currently seeking an exemption from federal safety standards for its new model of the 737 Max airliner. The safety standard in question is designed to prevent overheating and breaking off of part of the engine housing during flight. While federal officials have recognized the issue and instructed pilots to limit the use of the anti-icing system to mitigate potential damage, critics are expressing concerns about relying on human memory for safety measures. This article examines the implications of Boeing’s exemption request and the potential risks it poses to airline safety.
Boeing has asked the Federal Aviation Administration (FAA) to exempt its new model of the 737 Max from safety standards related to engine inlets and the anti-ice system until May 2026. The exemption is necessary for Boeing to commence delivering the smaller Max 7 to airlines. The company claims to be working on a long-term solution, which will undergo thorough testing and FAA review. However, the dependency on pilot memory and compliance with limiting the use of the anti-ice system raises concern among critics.
Pilots flying previous models of the Max, such as the Max 8 and Max 9, have already been warned to limit the use of the anti-icing system to five minutes in dry conditions. Failure to do so could lead to the engine inlets overheating, causing parts of the housing to break away and potentially strike the plane, leading to window damage and rapid decompression. A tragic incident in 2018 involving a Southwest Airlines flight and an older 737 serves as a grim reminder of the consequences of engine failure. An engine fan blade broke, causing a piece of loose engine housing to shatter a window and resulting in the death of a passenger. It is important to note that the overheating issue is specific to the Max models, as they utilize engine inlets made from carbon composite materials instead of metal.
Critics, including Dennis Tajer, a spokesman for American Airlines pilots, question the reliance on pilot memory for complying with the limitation on the anti-ice system. Concerns about potential fatalities due to human error are not unwarranted. Safety measures should not solely depend on pilot vigilance but instead incorporate a more foolproof approach. Additionally, the severity of the risk discovered during a test flight in 2017 prompted the FAA to issue warnings to pilots, emphasizing the potential hazards associated with the overheating problem.
A Boeing spokeswoman issued a statement acknowledging the company’s ongoing development of a long-term solution and its commitment to subjecting it to thorough testing and FAA review. However, little information has been provided about the specifics of this solution. Attention must be given to ensure that the proposed solution adequately addresses the safety concerns surrounding the engine overheating and breaking issue.
The Boeing 737 Max has faced significant safety concerns in recent years. In 2018 and 2019, two Max planes crashed, resulting in the tragic deaths of 346 individuals. These crashes prompted a worldwide grounding of all Max jets for almost two years while Boeing made necessary changes to the automated flight-control system, which was found to push the nose down based on faulty sensor readings. More recently, manufacturing flaws have interrupted Max deliveries, and airlines have been instructed to inspect the planes for potential loose bolts in the rudder-control system.
Boeing’s request for an exemption from safety standards to facilitate the delivery of the new 737 Max 7 model raises concerns about the reliance on pilot memory and compliance. The risks associated with engine overheating and breaking have already led to tragic accidents and fatalities in the past. While Boeing claims to be developing a long-term solution, it is crucial that this solution thoroughly addresses the safety issues and undergoes comprehensive testing and FAA review before implementation. The safety of airline passengers should never be compromised, and thus, all efforts must be made to ensure that the Boeing 737 Max operates under the highest safety standards.
