Common Mechanical Problems, Cures, And Prevention Spring slippage is a very common problem. Inspect the flute closely for closed or open keys that are not in their normal playing position. Remove the rubber band after the concert and get the spring replaced as soon as possible. Rubber left on the flute finish will cause horrible tarnish problems. An F key that won't close is a common problem caused by improper assembly technique.
Students bend the assembly while putting the flute together.
The F key foot must be bent back in postion and regulated when this happens. Make sure students avoid handling keys while assembling or keep keys closed while assembling. The C key hinge rod often works loose enough to allow the Bb-A keys to pop up. Tighten the screw to reset it, but not to tightly or the keys will bind. Other problems are associated mainly with adjustment screws needing tweaking.
