Indicates a non-functional door was used rather than in-oping an exit door and suggest retaining bolts were missing. If so, then there will be a paper trail back to whoever signed off that the bolts were installed.
Thanks, that explains in detail the working of the plug type door. Door must slide upwards to de-align the stop fittings. Door was thus creeping up by vibration during ground ops until it popped open after some cycles. So a massive quality problem in assembly, since they most likely forgot to install the four safety bolts (no damage to the fittings)
