> In practice, if a car recall required retorquing every bolt, the manufacturer would probably just declare them totaled instead of doing the repairs. Bear in mind that a 737 seats ~150 people and average car occupancy is somewhere around 1.5, so it's more like the value of 100 cars compared to the increased complexity of the checks. There are also very significant levels of inspection required as standard (something like 10 000 hours per year minimum) on an airliner compared to a personal vehicle (not including normal pre-flight checks). Even divided by 100 using the same maths as above, a car does not undergo anything LIKE 100 hours of inspection per year. Depending on where you live, you might have your car at the mechanics for a day every year or two to do a roadworthiness inspection. That said, I agree, it does seem like there are quite a lot of quality issues with these planes.
