## Discrepancy

DURING CRUISE, PILOT ENCOUNTERED SEVERE TURBULENCE WHICH INCLUDED A DESCENT OF ROUGHLY 400 FT IN 2 SECONDS. THE PLANE LANDED SAFELY AT THE INTENDED DESTINATION AIRPORT. GOT A TECH TO INSPECT THE PLANE IAW CH.5-5-00, FIRST LEVEL INSPECTION.  SEVERAL SPOTS ON THE TOP LT WING ABOUT 4 FT OTBD OF THE NACELLE THAT HAD MINOR WRINKLES AND 1 SPOT ON THE LT NACELLE THAT HAD A SMALL BULGE. DUE TO WEATHER AND SCHEDULING THE TECH COULD NOT COMPLY WITH THE, SECOND LEVEL INSPECTION, IAW THE MM.  THE PLANE REMAINS GROUNDED UNTIL FURTHER EVALUATION OF THE WRINKLES FOUND AND THE SECOND LEVEL INSPECTION CAN BE ACCOMPLISHED.
