NTSB to Test Dreamliner Components
National Transportation Safety Board (NTSB) investigators are set to conduct more tests on more components of Boeing’s grounded 787 Dreamliner on Tuesday in Arizona.

The board is continuing its investigation along with Japanese safety officials, Boeing and FAA into what caused a recent string of incidents including electrical fires and fuel leaks on Dreamliners operated by Japanese Airlines (JAL) and All Nippon Airways.
An examination of the flight recorder data from the JAL determined that the APU battery did not exceed its designed voltage of 32 volts, despite causing an electrical fire on the plane shortly after landing at Boston’s Logan International Airport on Jan. 7. Suspicions about problems with the battery prompted the U.S. and other nations to ground all 50 in-service Dreamliners indefinitely.
NTSB said on Tuesday investigators will examine the battery charger and download nonvolatile memory from the APU controller.
Officials still have not announced an anticipated return-to-service date for the grounded Dreamliners. More
