## Discrepancy

IN RNGARDS TO THE MD 500N HOLICOPTER, LHLS IS THE SECOND LIMO THAT I HAVE THE SAME ISSUE WITH THE NOTAR FAN BLADE ASSEMBLIES HAVING A STRANGO WEAR 
PALLERN ON THE SPAR PORTION OF THE BLADE ASSEMBLY. THESE FAN BLADES PIN: 500N5310-23 HAVO 3122.4 HRS TSN. NOT ALL THO BLADES HAVO THO SAMO 
ABOUT AND DEPLH OR WEAR AS IN LHE PREVIOUS 8010-4 FORM J SENT IN ON 
N520PC. THE OTHER ISSUE J HAD WITH THIS SEL OF NOTAR FAN BLADES IS THAT LHE PART NUMBERS AND SE,IAL NUMBERS HAVO WORN OFF LHO SPAR ASSEMBLY. WITHOUT THLS PERTINENT INFORMAHON I CAN NOT IDENTIFY WHAT BLADO IS WHAT THESE BLADES WERE ALSO MADE BY THO SAME VENDOR ROR MD HELICOPLORS. VENDOR CODE: 
5146. THE ONTY PART NUMBER I CAN MAKE OUT IS THE VENDOR PIN WHICH IS.
