What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) As the left engine rotated during the start cycle, and before it had fired, with hydraulic pressure rising, the nose gear collapsed while the aircraft was waiting on the apron to taxi out. The aircraft was on the chalks with electrical power provided by the auxiliary power unit. When the engine driven hydraulic pump begun to cause hydraulic pressure to rise, the main landing gear doors closed. Thereafter hydraulic pressure increased sufficient to actuate the nose gear over center and cause the aircraft to settle onto the nose gear doors as the nose gear itself slowly retracted. The aircraft sustained damage central to the nose gear door attaches points, which was determined by the NTSB to not be substantial. Investigation indicates no mechanical malfunction and pilot statements suggest no pilot error.
As the FAA filed it
(-23) AS THE LEFT ENGINE ROTATED DURING THE START CYCLE, AND BEFORE IT HAD FIRED, WITH HYDRAULIC PRESSURE RISING, THE NOSE GEAR COLLAPSED WHILE THE AIRCRAFT WAS WAITING ON THE APRON TO TAXI OUT. THE AIRCRAFT WAS ON THE CHALKS WITH ELECTRICAL POWER PROVIDED BY THE AUXILIARY POWER UNIT. WHEN THE ENGINE DRIVEN HYDRAULIC PUMP BEGUN TO CAUSE HYDRAULIC PRESSURE TO RISE, THE MAIN LANDING GEAR DOORS CLOSED. THEREAFTER HYDRAULIC PRESSURE INCREASED SUFFICIENT TO ACTUATE THE NOSE GEAR OVER CENTER AND CAUSE THE AIRCRAFT TO SETTLE ONTO THE NOSE GEAR DOORS AS THE NOSE GEAR ITSELF SLOWLY RETRACTED. THE AIRCRAFT SUSTAINED DAMAGE CENTRAL TO THE NOSE GEAR DOOR ATTACHES POINTS, WHICH WAS DETERMINED BY THE NTSB TO NOT BE SUBSTANTIAL. INVESTIGATION INDICATES NO MECHANICAL MALFUNCTION AND PILOT STATEMENTS SUGGEST NO PILOT ERROR.
