The pertinent flight data at the time the event was first discovered follows: the flight was in the climb phase; the speed was 200 KIAS; the aircraft was leveled off at FL220 and not the filed FL400 which was no longer feasible.Shortly after departure; a high oil pressure indication occurred on the number 1 engine. The value observed was an AMBER 48 PSI while the CLIMB lights for both engines were illuminated. Thrust was reduced on the number 1 engine from 95.1% N1 to 80% N1. The oil pressure value slowly reduced to 45-46 PSI for several seconds and then began to increase to an AMBER 48 PSI once again. After a few seconds; the AMBER indication turned to RED. So another engine number 1 thrust reduction was performed to 60% N1. The same decrease-increase oil pressure results occurred. So another engine number 1 thrust reduction was performed to flight idle. A similar decrease-increase oil pressure result occurred except this time a RED 49-50 PSI indication persisted. At this moment; we elected to execute the INFLIGHT ENGINE SHUTDOWN QRC. We then elected to proceed to our destination and [advise ATC of our situation.] The remaining enroute; approach; and landing phases were uneventful. Also; we did not require any emergency services from airport operations. Please note after a careful review of the existing work records in the aircraft log book; this 'oil pressure' anomaly has existed [for over three months] and has been documented on 9 different work records including today's discovery. This is nothing short of outrageous.
Hawker 800XP Captain reported an inflight shut down following a high oil pressure problem. Reporter stated the issue had been written up nine times over the last three months.
