Spring-eject is disabled at pressure difference by friction and on ground was probably avoided via glue by paint / stickiness of seals. These plugs are never opened. Maybe the springs not installed? Vibration in ground ops overcame the sticking after some cycles. At least the upper two bolts were clearly not installed or fell out, since the stop fitting eyes are completely undamaged on the pics.
