J.D. Morris writes. \"A common technique to keep mice out of small airplanes is to build little sheetmetal boxes (12 in. high) that are placed around the wheels.\" Mike Fredette tells how to make them. \"Go to the PMA/TSO dept of Home Depot. Buy 20ft of 10\" wide, flat gutter flashing sheet tin. Take a length of string and lay it around a main gear such that the diameter clears the outer gear door. Use the string length and cut a piece of tin that long, now you have a piece of tin 10\' wide by however long. On the 10\" end with some hand seamers, bend a 1/2\" tab back over nearly 180 deg. Important, bend one tab in one direction, the other tab in the opposite direction. Now stand the tin up on edge, wrap it around your gear leg, and \"hook\" the opposing tabs onto each other. Presto, 1 critter shield\"
