What was found
(CAN) FOLLOWING ITEMS FOUND INSTALLED: TRIANGLE DOUBLERS IAW SL 150-27; ANGLE STIFFENER NOT INSTALLED IAW SL 65-10. ANGLE STIFFENER MIGHT BE INSTALLED IAW PERSONAL PLANE SERVICE LTD (OTTAWA). DRAWING NR PPS.161. HAVE NOT BEEN ABLE TO FIND A COPY OF PPS 161, AT THIS TIME (MARCH 29, 2007). IF CRACKED PART IS A NON CONFORMING PART, NO FURTHER ACTION IS NEEDED. MY CONCERNS IS THIS: IF PART IS IAW PPS 161, AND NO FURTHER ACTION IS REQUIRED AFTER INSTALLATION (A VERY LONG TIME AGO) AND THEY ARE CRACKING IN SERVICE IT COULD BE QUITE SERIOUS, IN MY OPINION TO LOSE RUDDER CONTROL. THE AREA IN QUESTION IS ALSO VERY DIRTY AND HARD TO LOOK AT DUE TO OIL ACCUMULATION AND DIRT. (TC NR 20070405003)
