The problem: a switch in the engine fire suppression system can stick if it becomes too hot, failing to activate the two fire extinguishers. It affects all engines.
The potential result; an engine with a fire that burns through the wing. With potential on a long haul flight of having this go on for up to 3 hours, pilots are sounding alarm bells. It has the potential to be a disaster in the making.
The FAA admits there is a risk to the public, but it’s solution is only to check the switches every 30 days.
The criticism is that once again, a part only needs to fail once. Even if it’s checked it could go wrong the next day. Checking it doesn’t solve the problem.
So is the FAA’s job to calculate the risk to life and decide that it’s within an acceptable margin of error to take that risk? Or to be cautious and put human life above convenience and airline profits? That’s the concern post- Max disaster.
Boeing says just 1% of switches have failed and that they’re working on replacement parts with airlines.
Yet Boeing’s build approach at Charleston especially is under scrutiny as it raises production to 14 per month. Replacing 900 inspectors with technology assessments in quality control.
Pilots say it’s the cheap route, not the safe route; and that just about sums up why people have so little faith in the profit before people principle that seems to be modern Boeing.
