Composites Atlantic (CAL) declared that it has inked a multi-year contract with Bombardier Aerospace for the fabrication of composite parts on the horizontal stabiliser
for the Global 7000* and Global 8000* business aircraft.
On the MD-80 series airliners, the horizontal stabiliser
looks like a small wing mounted on top of the tail.
Alenia Aeronautica Foggia plant is also involved in this production where the horizontal stabiliser
is produced, consisting of two monolithic cocured boxes, 20 meters long and made, just as the fuselage and wings of the 787, of carbon fibre, with absolutely excellent design and production technologies.
Ratier-Figeac of France, a Hamilton Sundstrand business, supplies the aircraft with Trimmable Horizontal Stabiliser
Actuator (THSA), Throttle Control Assembly (TCA) and its Propeller System.
Sources inside the airframer and its supplier partners are quietly speculating that the horizontal stabiliser
is an insourcing candidate at a time when the structure is set to become significantly more complex for the larger 787-9, which will feature a new integral multispar box architecture and self-clearing laminar flow design to cut drag by 1%.
The BFU report explains: "The cause of the accident was that the horizontal stabiliser
broke up in flight due to aerodynamic flutter with the result that the aircraft could no longer be controlled.
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.
While the wingtips cleared one another, the RJ85's horizontal stabiliser
passed under and scored the right stabiliser of the RJ100.
1]s incorrectly positioned horizontal stabiliser
trim led the bomber to crash north-west of Guam on 21 July last year, killing all six crew.
HITCO Carbon Composites Inc has received a contract to supply the trailing edge components for the Boeing 787 horizontal stabiliser
