## Discrepancy

PDA 2  #1 ENGINE IDG SERVICE DOOR MISSING UPON LANDING AT SFO. A SDR REPORT MUST BE ACCOMPLISHED PDA CAT 2 # 1 ENGINE IDG DOOR WAS FOUND MISSING UPON LANDING AT SFO. OUR BELIEVE IS WHEN AIRCRAFT DEPARTING FROM EWR (FLT 1475) THE IDG DOOR WAS NOT FULLY LATCHED AND THE PART DEPARTING THE O/B COWLING ON CLIMB OUT. WE ASSUME THE CREW WAS NOT AWARE.
