NTSB report on Birmingham UPS cargo jet crash shows probable cause of crash


BIRMINGHAM, Ala. - A report obtained by WHNT News 19 from the National Transportation Safety Board (NTSB) shows more information on a UPS cargo jet crash that happened in August 2013.

A UPS plane crashed less than a mile away from the Birmingham Shuttlesworth International Airport on August 14, 2013. The two-member flight crew died in the crash of the Airbus cargo plane.

The NTSB report states the probable cause of the crash was due to the flight crew's "continuation of an unstabilized approach and their failure to monitor the aircraft's altitude during the approach, which led to an inadvertent descent below the minimum approach altitude and subsequently into terrain."

The report listed the following factors as contributing to the crash:

The flight crew's failure to properly configure and verify the flight management computer for the profile approach,

The captain's failure to communicate his intentions to the first officer once it became apparent the vertical profile was not captured,

The flight crew's expectation that they would break out of the clouds at 1,000 feet above ground level due to incomplete weather information

The first officer's failure to make the required minimums callouts,

The captain's performance deficiencies likely due to factors including, but not limited to, fatigue,
 distraction, or confusion, consistent with performance deficiencies exhibited during training,

The first officer's fatigue due to acute sleep loss resulting from her ineffective off-duty time management and circadian factors.
