What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The aircraft departed runway 3 at ste. After the landing gear was retracted, the electrical system failed. The pilot remained in the landing pattern for a return to runway 3. Prior to landing, the pilot selected the landing gear down but failed to verify that the gear was down and locked. The aircraft landed gear up on runway 3.
The investigation found that the aircraft master switch had been left on since the aircraft arrived in ste six days earlier (07/22/2016) and that the engine would not start initially due to a depleted battery. The pilot arranged for an external power start but the battery was not sufficiently charged prior to takeoff to handle anticipated electrical loads, including the normal operation of the landing gear. Personnel of the milwaukee FSDO arranged to have the aircraft raised from the ground and external electrical power applied. The landing gear was extended and locked into place utilizing the normal landing gear extension procedure. In addition, the voltage of the aircraft battery was 4.5 volts (12 volt capacity).
