NTSB narrative
THE ACFT WAS ON A TEST FLT AFTER A TOP-OVERHAUL HAD JUST BEEN COMPLETED. MECHANICS RPRTD THAT BEFORE THE FLT, THE ENG HAD BEEN PROPERLY RIGGED & OPERATED NORMALLY DRG RUN-UP. DRG INITIAL CLIMB AFTER TAKEOFF, WITNESSES SAID THE ENG LOST POWER. THE PLT INITIATED A STEEP (70-75 DEGREE BANKED) TURN BACK TOWARD THE ARP. DRG THE TURN, THE NOSE DROPPED & THE ACFT IMPACTED THE GROUND IN A LEFT WING LOW, NOSE DOWN ATTITUDE. THE ACFT WAS EXTENSIVELY DAMAGED BY IMPACT & GROUND FIRE. A TEARDOWN OF THE ENG REVEALED INTERNAL ENGINE MECHANICAL CONTINUITY, EVIDENCE OF OIL PUMP OPERATION, AND NORMAL LUBRICATION. THE DUAL MAG HAD EXTENSIVE FIRE DMG. THE FUEL PUMP WAS CHARRED; INVESTIGATORS WERE UNABLE TO ROTATE DRIVESHAFT. TEARDOWN DID NOT CONFIRM REASON FOR POWER LOSS.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1987-03-28.
