## Analysis

ABOUT 40 TO 45 MIN AFTER TAKEOFF PILOT NOTED ELECTRICAL LOAD METERS AT 0. ALTERNATOR WARNING LIGHTS WERE ON. RESET WAS ATTEMPTED BUT UNSUCCESSFUL DUE TO LOW BATTERY VOLTAGE. PLT DECIDED TO MAKE A PRECAUTIONARY LDG AT HOLLY SPRINGS, MS,BUT COULD NOT LOWER THE GEAR ELECTRICALLY. PLT THEN ATTEMPTED MANUAL EXTENSION BUT WAS UNABLE TO GET THE EMERGENCY CRANK, LOCATED BEHIND THE SEAT, UNSTOWED. PLT DECIDED TO MAKE A GEAR UP LANDING IN GRASS ALONGSIDE THE PAVED RWY. POST ACCIDENT EXAM OF THE ACFT FAILED TO REVEAL ANY FAILURE IN THE LANDING GEAR EXTENSION SYSTEM WHICH WOULD HAVE PREVENTED EXTENSION OF THE GEAR OR CAUSE OF THE ELECTRICAL SYSTEM FAILURE. THE PLT DID STATE THAT A LOAD ON THE LOAD METERS WAS NOTICED DURING ENGINE START AT JACKSON.

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19850208002969A](https://openairdocs.org/incident/19850208002969A), Feb 8, 1985: Beech 58, Holly Springs, MS, Destroyed. Battery too low to excite alternators. Unable to unstow manual extension handle. Landed gear up beside runway.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
