## Discrepancy

DURING A TEST FLIGHT FOR A SLAT ISSUE, THE LEFT FORWARD OUTBOARD FAIRING DEPARTED THE AIRPLANE. UPON INSPECTION, IT WAS NOTED THAT WHEN IT WAS INSTALLED IN MAY OF 2015, THERE WAS POOR SURFACE CONTACT WITH THE ADHESIVE SHOWING ABOUT 50 PERCENT SURFACE COVERAGE. BECAUSE IT RELIES ENTIRELY UPON THIS ADHESIVE FOR MOUNTING, THE LACK OF SURFACE CONTACT LIKELY PLAYED A LARGE ROLL IN ITS DEPARTURE.
