Nose gear doors opening in flight

[n86121]

A bazillion years ago when I first got my 'thrasher, sometimes the doors would open.

The design is/was that unless the locks are all engaged and circuit closed, doors open.

This prevents the gear from cycling UP or DOWN with doors closed.

Does your gear UP light go out? If it does, that's your smoking gun.

If the microswitches are 'edgy' they are easy to replace.
