I listed all "incidents." I used the NTSB definition. I included emergencies, "various no-flap landings" (in a CRJ -- which was common at one time,) smoke events, single-hydraulic events, engine failures.
No questions were asked.
There is no computer that scans your app and disqualifies you for exceeding a certain amount of incidents.
The more hours you have, the more incidents you'll have.
