A Jayawijaya Boeing 737-200, registration PK-JRW performing a non-scheduled freight flight from Jayapura to Wamena (Indonsia) with 4 crew and 12,556 kg of cargo, was accelerating for takeoff from Jayapura's runway 30 when at rotation speed a loud bang was heard and severe vibrations were felt. The pilot monitoring noticed the right hand engine (JT8D) indications were equal to idle power with the EGT fluctuating. The crew stopped the climb at 4500 feet, worked the engine severe damage checklists and returned to Jayapura for a safe landing.
