What was found
DURING ROUTINE 100 HOUR INSP, A CRACK IN THE HINGE OF THE ENGINE FAIRING WAS FOUND RADIATING FROM THE 2ND HOLE FROM ONE END OF THE HINGE WITH THE CORNER HAVING SEPARATED FROM THE HINGE FROM CRACKS EMANATING FROM THE 1ST HOLE. THIS IS A COMMON FAILURE FOR THIS PART. THE SURFACE UNDER THE HINGE IS UNEVEN AND GIVES UNEVEN SUPPORT TO THE HINGE WHEN BOLTED DOWN. SUGGEST USING A STRONGER MATERIAL SUCH AS STAINLESS STEEL FOR THE HINGE OR IMPROVING THE SURFACE CONTOUR AND STRENGTH OF THE FAIRING HINGE MOUNTING SURFACE. (K)
