Analysis

Shortly after climbing & leveling at 6000 ft, the r eng bmep gage indicated a rapid power loss & the r eng RPM 'increased out of control' to about 3100 RPM. The aircrew retarded the r throttle & reduced the r eng to 2100 prm by using the prop increase/decrease toggle sw. The aircrew were unable to feather the r prop or maintain alt, so they diverted to the nearest arpt (walker county). While turning downwind for rwy 9, the r eng fire indicator activated & the coplt confirmed a fire. Both fire bottles were discharged & the r prop stopped rotating. Injection water for the l eng was exhausted & the l eng began backfiring. The captain then maneuvered & landed on rwy 27. After touchdown, the r main tires failed, the acft veered off the r side of the rwy & hit a ditch & the gear collapsed. An exam revealed the #6 cyl link rod &/or piston in the r eng had failed, resulting in further damage to the eng & #6 cyl. Subsequently, fire & heat caused the r eng to seize & also damged the r main tires which failed at touchdown.
