Tail mistake 'caused B52 crash'

[JS50557]

A deadly B52 bomber crash off Guam last year was caused by part of the plane's tail assembly being set in the wrong position, a US Air Force investigation report said.

The plane's stabiliser trim was improperly set between 4.5 and 5.0 degrees nose-down at impact, indicating the aircraft had been in a nose-down descent at low altitude, according to a report by the Air Combat Command in Langley, Virginia.

The stabiliser trim is used in conjunction with the aircraft's elevator to control the pitch of the aircraft.
