The FAA is adopting a new Airworthiness Directive (FAA-2011-0518) for Airbus A300/310 airliners to prevent high loading of the vertical stabilizer caused by excessive rudder pedal inputs, which could cause failure of the vertical stabilizer and consequent loss of control. The AD, effective Dec. 14, 2012, applies to A300 B4-600, B4-600R, F4-600R and C4-605R Variant F airplanes (collectively called the A300-600 series), as well as to the A310 series.
A Syrian Arab Airlines A320 sustained serious damage September 20 when it collided feet with a Syrian military Mi-8 helicopter at 12,000 feet over Duma, Syria. At press time, sources still could not confirm whether the aircraft was on approach to Damascus International Airport (OSDI) or had just departed. The aircraft landed safely without injuries to anyone on board. The Airbus lost a significant portion of its vertical stabilizer. The helicopter, however, crashed, killing both pilots.
Jet Aviation Basel has added a tail and wing dock certified for the 737-based BBJ and Airbus A320 to its widebody hangar. This new dock platform will help to shave up to six weeks off aircraft downtime during 12-year inspections by providing access to all areas of the tail on all four levels, as well as access for full structural inspection of the wings.
An FAA NPRM for the Challenger 300 horizontal stabilizer trim actuator states the No Back and the Number 1 motor brake assembly can both fail dormant. “…failure of the [system] along with a
Effective yesterday, an EASA Airworthiness Directive (AD) has restored the full original flight envelope for the Dassault Falcon 7X, providing the fly-by-wire control system is updated. Dassault has developed a modification of the system to improve “the monitoring and reversion logic of the horizontal stabilizer trim system,” EASA said.
Italy’s Alenia Aeronautica will now serve as a “second source” of the composite horizontal stabilizer for the Boeing 787-9 under a plan to move primary responsibility for the component to Boeing’s Advanced Development Center in Seattle. Under a new contract Boeing recently signed with Alenia, the Italian manufacturer will lose its position as prime contractor for the component starting in 2013, according to a Boeing statement.
Boeing insists that a newly identified assembly flaw with the Boeing 787's horizontal stabilizers will not delay service entry of the new airliner, which is scheduled for the end of this year. On June 24, engineers discovered a production quality issue with the brackets that attach the stabilizer to the fuselage.
The November 2006 fatal crash of the Grob G180A SPn prototype was caused by failure of the twinjet’s horizontal stabilizer, which “suffered an in-flight breakup due to aerodynamic flutter,” according to the final report issued by the German Federal Bureau of Aircraft Accident Investigation (BFU). While the cause of the flutter was

It took eight months of waiting since its industrial launch, but the C Series finally drew its first firm orders this month, putting to rest gathering speculation by industry observers that the airplane might never materialize.
