What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Aircraft lost electrical power. Pilot performed emergency landing gear extension and landed without incident. After departing the runway the aircraft came to a stop. When applying power to taxi, the nose gear collapsed striking the propeller and lower engine cowling. Inspection revealed that the nose gear down lock link was stiff and gritty. The emergency extension allows the gear to free fall to the down and locked position. With the down lock link stiff and gritty, the free fall of the nose gear did not completely force the link overcenter, therefore not providing a positive downlock. When power was applied, the nose gear collapsed.
As the FAA filed it
(-23) AIRCRAFT LOST ELECTRICAL POWER. PILOT PERFORMED EMERGENCY LANDING GEAR EXTENSION AND LANDED WITHOUT INCIDENT. AFTER DEPARTING THE RUNWAY THE AIRCRAFT CAME TO A STOP. WHEN APPLYING POWER TO TAXI, THE NOSE GEAR COLLAPSED STRIKING THE PROPELLER AND LOWER ENGINE COWLING. INSPECTION REVEALED THAT THE NOSE GEAR DOWN LOCK LINK WAS STIFF AND GRITTY. THE EMERGENCY EXTENSION ALLOWS THE GEAR TO FREE FALL TO THE DOWN AND LOCKED POSITION. WITH THE DOWN LOCK LINK STIFF AND GRITTY, THE FREE FALL OF THE NOSE GEAR DID NOT COMPLETELY FORCE THE LINK OVERCENTER, THEREFORE NOT PROVIDING A POSITIVE DOWNLOCK. WHEN POWER WAS APPLIED, THE NOSE GEAR COLLAPSED.
