Narrative:
Climbing through 7900 to 9000 ft on a flight (air ambulance) from hnl-ito, I experienced a drop in manifold pressure on the right engine to about 21 inches to 24 inches. I immediately notified center to return to hnl and also a leveloff, or if able, lower altitude. I was given 4000 ft. I ran the emergency checklist, but did not shut down the engine because it was still developing partial power. I declared an emergency and landed back at hnl. The mechanics discovered that the turbocharger had seized in-flight.

Title: A SMALL LOW WING, 2 RECIPROCATING ENG ACFT IN CLB DECLARED AN EMER AND DIVERTED DUE TO LOSS OF PWR ON #2 ENG CAUSED BY A SEIZED TURBOCHARGER.
Narrative: CLBING THROUGH 7900 TO 9000 FT ON A FLT (AIR AMBULANCE) FROM HNL-ITO, I EXPERIENCED A DROP IN MANIFOLD PRESSURE ON THE R ENG TO ABOUT 21 INCHES TO 24 INCHES. I IMMEDIATELY NOTIFIED CTR TO RETURN TO HNL AND ALSO A LEVELOFF, OR IF ABLE, LOWER ALT. I WAS GIVEN 4000 FT. I RAN THE EMER CHKLIST, BUT DID NOT SHUT DOWN THE ENG BECAUSE IT WAS STILL DEVELOPING PARTIAL PWR. I DECLARED AN EMER AND LANDED BACK AT HNL. THE MECHS DISCOVERED THAT THE TURBOCHARGER HAD SEIZED INFLT.
