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.

Narrative: the corporate owned and operated aircraft departed bdl to conduct local training with company pilot and hired flight instructor. During airwork pilot lowered gear to conduct an approach to landing stall. Nose gear down light did not indicate down & locked. Pilot noted no hydraulic pressure and returned to bdl for fly-by. Both pilot and controller noted nose gear in down position. Pilot landed and lowered nose slowly. Nose gear collapsed, only minor damage to fuselage in area of nose gear. Investigation revealed that the nose gear down lock failed to engage when the snap ring retainer in the lower drag link failed. The snap gear drag brace to displace under hydraulic pressure and jam the over-center latching mechanism. This also resulted in a complete loss of hydraulic pressure due to fluid loss. Both alternators went off line when the electric auxiliary hydraulic pump current limiter was blown, probably the result of overheating due to fluid loss. privacy data omitted

As the FAA filed it

NARRATIVE: THE CORPORATE OWNED AND OPERATED AIRCRAFT DEPARTED BDL TO CONDUCT LOCAL TRAINING WITH COMPANY PILOT AND HIRED FLIGHT INSTRUCTOR. DURING AIRWORK PILOT LOWERED GEAR TO CONDUCT AN APPROACH TO LANDING STALL. NOSE GEAR DOWN LIGHT DID NOT INDICATE DOWN & LOCKED. PILOT NOTED NO HYDRAULIC PRESSURE AND RETURNED TO BDL FOR FLY-BY. BOTH PILOT AND CONTROLLER NOTED NOSE GEAR IN DOWN POSITION. PILOT LANDED AND LOWERED NOSE SLOWLY. NOSE GEAR COLLAPSED, ONLY MINOR DAMAGE TO FUSELAGE IN AREA OF NOSE GEAR. INVESTIGATION REVEALED THAT THE NOSE GEAR DOWN LOCK FAILED TO ENGAGE WHEN THE SNAP RING RETAINER IN THE LOWER DRAG LINK FAILED. THE SNAP GEAR DRAG BRACE TO DISPLACE UNDER HYDRAULIC PRESSURE AND JAM THE OVER-CENTER LATCHING MECHANISM. THIS ALSO RESULTED IN A COMPLETE LOSS OF HYDRAULIC PRESSURE DUE TO FLUID LOSS. BOTH ALTERNATORS WENT OFF LINE WHEN THE ELECTRIC AUXILIARY HYDRAULIC PUMP CURRENT LIMITER WAS BLOWN, PROBABLY THE RESULT OF OVERHEATING DUE TO FLUID LOSS. ^PRIVACY DATA OMITTED^
