Gear Doors will not close

[Ernie Martin]

This is NOT likely to be the issue, but if the above suggestions and other efforts fail to find the problem, check your speed when lowering and retracting the gear. Notice that it worked fine on retraction (when you are climbing and tend to be at a slower speed) but the doors failed to close on your descent, when you tend to have a higher speed.

If you look at the open doors -- especially the rear ones -- they are BIG and act like a small parachute. I'm thinking that if the powerpack is weak, it will work fine while you climb because of your lower speed, and it will lower the gear on descent, but it might be struggling trying to close the doors on your faster descent. I bring my speed down to under 130 MPH to drop the gear.

Again, follow all other suggestions first, but check this if all others fail.
