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.

(-23) A Beechcraft bonanza H35 (N353B) landed at Eugene Oregon on runway 34R, during rollout after landing the nose gear slowly collapsed resulting in propelle striking the ground and a sudden engine stoppage. Pilot had noticed that prior to landing electrical power was weak, so he reduced electrical load. When he selected gear down the gear appeared to lower normally with a down light indication. Prior to landing pilot asked tower to observe landing gear position, tower indicated gear appeared down. Pilot tried to rotate the emergency gear hand crank in flight, he believed the gear was down and locked. The maintenance technician assisting with the airplane removal stated he observed the main landing gear inboard doors were drooped down when he arrived to recover N353B from runway 34R which indicates the gear are not fully down and locked. The maintenance technician turned the emergency hand crank approximately 10 rotations to fully lock the main gear prior to towing. Post accident investigation revealed that battery acid specific gravity level was very low and the alternator field wire was broken at the alternator resulting in battery not being charged.

As the FAA filed it

(-23) A BEECHCRAFT BONANZA H35 (N353B) LANDED AT EUGENE OREGON ON RUNWAY 34R, DURING ROLLOUT AFTER LANDING THE NOSE GEAR SLOWLY COLLAPSED RESULTING IN PROPELLE STRIKING THE GROUND AND A SUDDEN ENGINE STOPPAGE. PILOT HAD NOTICED THAT PRIOR TO LANDING ELECTRICAL POWER WAS WEAK, SO HE REDUCED ELECTRICAL LOAD. WHEN HE SELECTED GEAR DOWN THE GEAR APPEARED TO LOWER NORMALLY WITH A DOWN LIGHT INDICATION. PRIOR TO LANDING PILOT ASKED TOWER TO OBSERVE LANDING GEAR POSITION, TOWER INDICATED GEAR APPEARED DOWN. PILOT TRIED TO ROTATE THE EMERGENCY GEAR HAND CRANK IN FLIGHT, HE BELIEVED THE GEAR WAS DOWN AND LOCKED. THE MAINTENANCE TECHNICIAN ASSISTING WITH THE AIRPLANE REMOVAL STATED HE OBSERVED THE MAIN LANDING GEAR INBOARD DOORS WERE DROOPED DOWN WHEN HE ARRIVED TO RECOVER N353B FROM RUNWAY 34R WHICH INDICATES THE GEAR ARE NOT FULLY DOWN AND LOCKED. THE MAINTENANCE TECHNICIAN TURNED THE EMERGENCY HAND CRANK APPROXIMATELY 10 ROTATIONS TO FULLY LOCK THE MAIN GEAR PRIOR TO TOWING. POST ACCIDENT INVESTIGATION REVEALED THAT BATTERY ACID SPECIFIC GRAVITY LEVEL WAS VERY LOW AND THE ALTERNATOR FIELD WIRE WAS BROKEN AT THE ALTERNATOR RESULTING IN BATTERY NOT BEING CHARGED.
