## Discrepancy

(CAN) OLEO WENT FLAT, LOST ALL OIL AND NITROGEN AFTER A NORMAL LANDING.  AIRCRAFT WAS FUELED AND CREW DEPARTED FOR 7 HOURS - UPON RETURN, OLEO WAS FLAT.  LANDING GEAR HAD BEEN OVERHAULED AND INSPECTED FOR FIVE YEAR REQUIREMENT 07/12/99.  UPON INSPECTION OF ASSY, UPPER SEAL 'O' RING WAS FOUND TO BE ROLLED AND ABRADED ALMOST 1/4 OF CIRCUMFERENCE.  NEW SEAL INSTALLED.  NOTE:  THERE IS A SPECIFIC PROCEDURE FOR INSTALLATION IN COMPONENT MAINTENANCE MANUAL.
