flight safety detectives episode 223 - electrical failure leads to 727 crash in pacific ocean

The crew of a United Airlines 727 tried to turn back shortly after takeoff from Los Angeles, but did not make it back to the airport. The plane crashed into the Pacific Ocean.

Greg Feith, Todd Curtis, and John Goglia discuss the crash of the 727-22QC in 1969. Electrical failures and electrical system design contributed to the plane crash. The accident happened on a night with limited visibility due to the weather.

The aircraft had three electrical generators, but only two were working. Shortly after takeoff, the crew shut down one engine due to a fire warning. That move shut down one of the two working generators.
​
John discusses the complexities of 727 electrical systems and other aircraft of the era. The NTSB found that total power loss occurred after all the electrical loads were placed on the one remaining generator.
