What was found
DURING CRUISE FLIGHT THE MASTER WARNING LIGHT AND AUDIO ALERTED. WHEN SCANNING THE GAUGES, I NOTICED THE TRANSMISSION PRESSURE DROP BELOW LIMITS. BRIEFED THE CREW WHAT WAS HAPPENING AND TOLD THEM WE HAVE TO FIND A PLACE TO LAND NOW. WE AREN'T GOING TO MAKE IT FURTHER. I STARTED A SLIGHT DECENT. SPOTTED A HIGH SCHOOL LESS THAN A MILE DIRECTLY IN FRONT OF US. DECIDING TO HEAD TO THE SCHOOL, THE ENGINE PRESSURE ROSE ABOVE LIMITS. STARTED A GRADUAL CIRCLING DECENT TO THE HIGH SCHOOL PARKING LOT. TOLD THE CREWMEMBERS TO TIGHTEN UP THEIR SEATBELTS JUST IN CASE. LANDED AND IMMEDIATELY SHUT DOWN THE HELICOPTER.
