If you’ve been paying attention to the industry news, you’ve seen the multiple stories about the fuselage ruptures on the 737-300.  It appears that there is metal fatigue on the lap joints at the top of the fuselage on some of the older aircraft.

It appears that these aircraft actually passed the typical inspections performed by the airlines (using visual, eddy current, or ultrasonic inspection).

Naturally, you can expect to see some sort of revised inspection process.
