What was found
DURING AN ANNUAL INSP, THE INSPECTOR FOUND WHAT APPEARED TO BE A CRACK EXTENDING FWD OF THE OTBD AILERON HING ATTACH BRACKET, LT AILERON, IN THE AILERON L/E RIB. THE AILERON WAS REMOVED AND THE AILERON OUTER HINGE BRACKET WAS REMOVED. PAINT WAS CHEMICALLY REMOVED EXPOSING A CRACK WHICH CONNECTS THE TWO NUT-PLATE ATTACHMENT RIVETS. THE TECH THEN REMOVED THE RT AILERON AND PERFORMED THE SAME PROCEDURE. THE L/E RIB IS NOT CRACKED ON THE RT AILERON, HOWEVER THE SKIN HAS DEFINATELY BEEN WORKING AND APPEARS THAT IT WILL CRACK FROM WORK HARDENING VERY SOON.
