PA-32 reported a nose gear collapse on the first takeoff attempt after annual inspection. The aircraft was removed from the runway and moved to a hangar for inspection and repair.

Narrative

On the first attempted flight after Annual Inspection; my aircraft nose gear collapsed during takeoff roll; resulting in a prop strike. This occurred on Day 1 at XA:30 am. I then traveled out of state on Day 2; but contracted COVID on Day 3 and was unable to travel home until Day 4. This delayed my filing of this report until today. The aircraft was just out of its annual inspection; so I directed my wife to wait in the terminal while I conducted a first flight alone (after which we planned to make a short trip together). I performed a full preflight inspection; taxied to the runup area uneventfully; performed a full runup and pre-takeoff checklist. There were no audible alarms and gear indicators showed three greens. Takeoff roll began normally and then suddenly the nose gear collapsed; causing a prop strike and a skid to a stop. I immediately shut the throttle; mixture; fuel valve cutoff; fuel pump; and mags. I made a short radio call to alert others to the Runway blockage; then shut off electrical switches and master switch and exited the plane. This occurred well before rotation speed; although the plane may have lightened itself slightly on its gear. Photos showed the main gear remained fully locked. The plane was towed to my hangar and has not been touched since then (as far as I am aware - keeping in mind I was away; sick; for a week). We are still trying to determine what could have caused the failure; but I am glad to have treated this like a test flight.
