Nose gear doors are open after landing

[hharney]

Sounds like a bad wire or connector to the micro switch. If it is only the nose gear doors then I would check the micro switch that is closed when the gear is extended. If there is a short or bad connection the doors will not close because the system thinks the nose gear is not down. Check the wires, connector and switch carefully as it is 99% something really simple and just a bad connection
