You completely miss the point and do not understand that given the choice between two parts that meet the same standard, manufacturers will usually opt for the less expensive part that has a shorter life span than the more expensive one that lasts longer for two reasons (neither having to do with safety or liability.)
1.) It costs less to make the vehicle or product.
2.) They make more money in repair costs down the line as the parts have to be replaced more often, which also includes the labor costs.
Airbus, Boeing, and every other vehicle or product manufacturer are in business for one reason. To make money. That's why you can buy a car for $20,000 but the parts for that car, if bought individually, would add up to $80,000. There is a manufacturer of an orange colored rubber radiator hose that can last the car's lifetime. It's more expensive than the black hose, but not by much. Why don't the manufacturers use it? The two reasons above.
That's why you only have to pay $1,300 for a 65" Sony or LG LED flatscreen TV. What the manufacturers don't advertise, however, is that TV is made with such cheap parts due to competition, that you'll have to replace the main computer board or the power supply board within 5 years at a cost of $400 or more. Every five years. The old CRT TV's lasted 20 years. Gone are those days.
