Narrative:

Mem to oak, B747 (cargo). Maintenance log revealed previous write-ups concerning #1 and #4 thrust reversers. Maintenance signed them off as operational. Company policy dictates that reversers are to be used for landing and rejected takeoffs only, therefore I was unable to determine if the reversers were operational until I reached my destination and applied reverse thrust. #1 and #4 reversers did not work. I feel I was lied to by maintenance.

Original NASA ASRS Text

Title: FLC FOUND A MAINT SIGNOFF IN ERROR. THE ENG REVERSERS SIGNED OFF AS OPERATIONAL, DID NOT WORK.

Narrative: MEM TO OAK, B747 (CARGO). MAINT LOG REVEALED PREVIOUS WRITE-UPS CONCERNING #1 AND #4 THRUST REVERSERS. MAINT SIGNED THEM OFF AS OPERATIONAL. COMPANY POLICY DICTATES THAT REVERSERS ARE TO BE USED FOR LNDG AND REJECTED TKOFS ONLY, THEREFORE I WAS UNABLE TO DETERMINE IF THE REVERSERS WERE OPERATIONAL UNTIL I REACHED MY DEST AND APPLIED REVERSE THRUST. #1 AND #4 REVERSERS DID NOT WORK. I FEEL I WAS LIED TO BY MAINT.
