What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Aircraft was being flown as a test flight after completion of a annual inspection. Slightly before rotation speed (aprox 80KTS) the nose gear collapsed casing minor damage to the underbelly and prop strikes on both engines. A departing piece of prop also damaged the leading edge of the right wing half way down the wing.
Aircraft annual inspection was not endorsed prior to the test flight action. The aircraft had been issued a new n# several years ago and the airworthiness cert was never updated.
