Kingsley Airman pioneers critical wing spar inspection
Childs fixture, seen at the top of the photo, keeps the bit steady while he makes the most crucial final pass where it’s possible to unintentionally cut into the wing spar itself. He holds the drill lightly with both hands where he can sense even the slightest change in vibration. On two occasions he sensed the cutting tool was cutting through the skin and into the spar; he stopped the cut he saved a bill that could tally more than one million dollars.
