In addition to Earhart and Noonan, Harry Manning and Mantz (who was acting as Earhart's technical advisor) were on board. Due to lubrication and galling problems with the propeller hubs' variable pitch mechanisms, the aircraft needed servicing in Hawaii. Ultimately, the Electra ended up at the United States Navy's Luke Field on Ford Island in Pearl Harbor. The flight resumed three days later from Luke Field with Earhart, Noonan and Manning on board. During the takeoff run, there was an uncontrolled ground-loop, the forward

The radio direction finding station at Darwin expected to be in contact with Earhart when she arrived there, but Earhart stated that the RDF was not functioning; the problem was a blown fuse. During a test flight at Lae, Earhart could hear radio signals, but she failed to obtain an RDF bearing. While apparently near Howland Island, Earhart reported receiving a 7500 kHz signal from "Itasca", but she was unable to obtain an RDF bearing. The antennas
