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) Pilot stated that he had taken off from Tucson at 4:00 am enroute to Texas when he experienced a total electrical failure. He returned to Tucson, extended the landing gear by the emergency method and landed. Upon landing, the nose gear collapsed causing the aircraft to depart the side of the runway. The aircraft experienced damage to the fuselage, vertical and horizontal tail surfaces, right and left wing tips, propeller and engine. The investigation is on-going to determine the cause of the electrical system failure. (-23 amendment) continued investigation of original accident report dated 02/18/2004 revealed that the bracket securing the alternator to the engine was broken causing the main terminals to separate. The pilot had stated that most of the damage was due to the nose wheel collapsing during the landing, however subsequent investigation revealed that the right main gear was not in the down and locked position, most likely due to inadequate emergency gear extension procedures.

As the FAA filed it

(-23) PILOT STATED THAT HE HAD TAKEN OFF FROM TUCSON AT 4:00 AM ENROUTE TO TEXAS WHEN HE EXPERIENCED A TOTAL ELECTRICAL FAILURE. HE RETURNED TO TUCSON, EXTENDED THE LANDING GEAR BY THE EMERGENCY METHOD AND LANDED. UPON LANDING, THE NOSE GEAR COLLAPSED CAUSING THE AIRCRAFT TO DEPART THE SIDE OF THE RUNWAY. THE AIRCRAFT EXPERIENCED DAMAGE TO THE FUSELAGE, VERTICAL AND HORIZONTAL TAIL SURFACES, RIGHT AND LEFT WING TIPS, PROPELLER AND ENGINE. THE INVESTIGATION IS ON-GOING TO DETERMINE THE CAUSE OF THE ELECTRICAL SYSTEM FAILURE. (-23 AMENDMENT) CONTINUED INVESTIGATION OF ORIGINAL ACCIDENT REPORT DATED 02/18/2004 REVEALED THAT THE BRACKET SECURING THE ALTERNATOR TO THE ENGINE WAS BROKEN CAUSING THE MAIN TERMINALS TO SEPARATE. THE PILOT HAD STATED THAT MOST OF THE DAMAGE WAS DUE TO THE NOSE WHEEL COLLAPSING DURING THE LANDING, HOWEVER SUBSEQUENT INVESTIGATION REVEALED THAT THE RIGHT MAIN GEAR WAS NOT IN THE DOWN AND LOCKED POSITION, MOST LIKELY DUE TO INADEQUATE EMERGENCY GEAR EXTENSION PROCEDURES.
