NTSB Reports: May 2017
The pilot reported that when he raised the landing gear shortly after takeoff, he heard a loud crunch as the gear entered the wells. The pilot climbed the airplane to about 3000 feet and observed the landing gear circuit breaker was popped and the alternator was off. The pilot attempted to extend the landing gear normally several times, however, the circuit breaker popped each time and the gear remained retracted. The pilot also attempted to use the emergency gear extension, to no avail.
