The Federal Aviation Administration has been forced to issue an airworthiness directive for the Boeing 737 MAX.
The AD issued relates to a safety risk around the engine powering the 737 MAX, specifically through its anti-ice or EAI system only under certain conditions.
CFM engines, specifically the Leap-1B engines, are the centre of the focus for this AD. The FAA says that if the system was to be used for five or so minutes or even more than during certain conditions, there is the risk that overheating can occur of the engine inlet inner barrel.
Boeing has said that it supports the Federal Aviation Administration in its findings. While there isn’t a safety incident yet is aware that there is a potential for a portion of the inlet to exceed its designed temperature range.
The American plane maker further adds that it is working diligently with customers impacted to deploy the appropriate measures to ensure no safety risk occurs. This is because Boeing has sourced the measures to mitigate the problem, but a more permanent fix is still required.
An inlet loss can cause fuselage or window damage, which has potentially severe implications for those inside the aircraft and the stability of the 737 MAX being flown.
From here, the process will be to find ways to mitigate the problem under a permanent fix can be determined, but the vision would be for this not to impact deliveries or broader operations.
