Story of the Tapper
When the composites group in CNDE took on the job of modernizing the old practice
of coin tap four years ago, they had no idea that they would one day use the
instrument they developed to map out damages on a rudder of an Airbus A300 failed
by its composite tail. Neither had they thought that the device would attract attention
of inspectors for racing sail boats from overseas.
Tap test is an age-old technique for inspecting composite parts on aircraft for flaws
and damages, especially on movable control surfaces such as rudders, spoilers and
flaps. In this technique one takes a hand-held mass, such as a coin or a machined
piece of metal, and tap on the surface. A good region without defects or damages
would produce a crisp and solid sound whereas a bad or damaged region would
give a dud sound. The method is simple and cheap, but is also subjective, inaccurate
and operator dependent. Over the years there have been a number of attempts to
instrument the tap test and remove the dependence on human hand and ear. These
efforts resulted in several instrumented tap test devices on the market; however,
they have stopped short of bringing in another powerful tool in nondestructive
