From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(.4)During a landing approach, the pilot noted that the right engine remained at a high power setting, when he moved the power levers to reduce power. He executed a missed approach and had difficulty keeping the airplane straight and level. The pilot maneuvered for a second approach to land. After landing, he could not maintain directional control of the airplane and tried to go around, but the airplane went off the end of the runway and impacted the localizer antenna. The pilot did not advise ATC of the problem nor did he declare an emergency. The pilot's operating handbook stated that for a power plant control malfunction, the affected engine should be shut down, and a single engine landing should be made. The power control cable was found disconnected from the anchoring point. A safety tab was broken off the housing, allowing it to unscrew. About one month before the accident, maintenance had been performed on the right engine to correct a discrepancy about the right engine power lever being stiff. The mechanic re-rigged the right engine power cable.

As the FAA filed it

(.4)DURING A LANDING APPROACH, THE PILOT NOTED THAT THE RIGHT ENGINE REMAINED AT A HIGH POWER SETTING, WHEN HE MOVED THE POWER LEVERS TO REDUCE POWER. HE EXECUTED A MISSED APPROACH AND HAD DIFFICULTY KEEPING THE AIRPLANE STRAIGHT AND LEVEL. THE PILOT MANEUVERED FOR A SECOND APPROACH TO LAND. AFTER LANDING, HE COULD NOT MAINTAIN DIRECTIONAL CONTROL OF THE AIRPLANE AND TRIED TO GO AROUND, BUT THE AIRPLANE WENT OFF THE END OF THE RUNWAY AND IMPACTED THE LOCALIZER ANTENNA. THE PILOT DID NOT ADVISE ATC OF THE PROBLEM NOR DID HE DECLARE AN EMERGENCY. THE PILOT'S OPERATING HANDBOOK STATED THAT FOR A POWER PLANT CONTROL MALFUNCTION, THE AFFECTED ENGINE SHOULD BE SHUT DOWN, AND A SINGLE ENGINE LANDING SHOULD BE MADE. THE POWER CONTROL CABLE WAS FOUND DISCONNECTED FROM THE ANCHORING POINT. A SAFETY TAB WAS BROKEN OFF THE HOUSING, ALLOWING IT TO UNSCREW. ABOUT ONE MONTH BEFORE THE ACCIDENT, MAINTENANCE HAD BEEN PERFORMED ON THE RIGHT ENGINE TO CORRECT A DISCREPANCY ABOUT THE RIGHT ENGINE POWER LEVER BEING STIFF. THE MECHANIC RE-RIGGED THE RIGHT ENGINE POWER CABLE.
