Don't know about self locking doors however, we had a self opening cabin door at 140 kts. Apparently it happened all on it's own.....ems primary scene response, rotors running recovery, a " rush rush" culture with our organization here in the sandpit, no use of any form of checklist.....hmmm, yep, happened all on it's own.....come to think of it, where can we get those self locking cargo doors
Cheers
