If a plane lost its horizontal stabiliser
, it would be unable to keep the nose pointed at the proper angle up or down, and the plane would begin an uncontrollable dive.
Ratier-Figeac of France, a Hamilton Sundstrand business, supplies the aircraft with Trimmable Horizontal Stabiliser

While concerns about availability of Rolls-Royce Trent 1000 engines dog its 787 programme, Boeing continues to wrestle with workmanship issues on the aircraft's Alenia-built horizontal stabiliser
. Boeing Commercial Airplanes chief executive Jim Albaugh says Boeing will have to "do some re-shimming and we'll have to do some analysis" on most of the existing crop of 27 stabilisers already delivered from Italy to final assembly in Everett, though "we're not too worried" about later units, thanks to Boeing personnel at Alenia's Foggia facility.
The company had previously indicated that the cumulative impact of a series of issues, including supplier workmanship issues related to the horizontal stabiliser
and instrumentation delays could push first delivery of the 787 a few weeks into 2011.

The American Airlines aircraft apparently had the tip of one of its wings sheared off when it clipped the horizontal stabiliser
of the Delta aircraft.
The incident occurred as the aircraft was descending though 6,000 feet on approach to the Paris airport and the flight crew said that the aircraft did not respond as expected to control column inputs and that the horizontal stabiliser
trim was used for pitch control.
Problems with the aircraft's horizontal stabiliser
are believed to have been a factor in the accident.
