Federal Aviation Administration December 21, 2005 – Federal Register Recent Federal Regulation Documents

First Meeting: RTCA Special Committee 207/Airport Security Access Control Systems
Document Number: 05-24320
Type: Notice
Date: 2005-12-21
Agency: Federal Aviation Administration, Department of Transportation
The FAA is issuing this notice to advise the public of a meeting of RTCA Special Committee 207, Airport Security Access Control Systems.
Airworthiness Directives; Bombardier Model DHC-8-400 Series Airplanes
Document Number: 05-24245
Type: Rule
Date: 2005-12-21
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model DHC-8-400 series airplanes. This AD requires an inspection of the laminated shims for cracks, damage, or extrusion between the forward attachment fittings of the horizontal stabilizer and the top rib of the vertical stabilizer; a torque check of the attachment bolts in the attachment fittings of the front, middle, and rear spars; and corrective actions if necessary. This AD results from a report indicating that delaminated shims extruded from the interface between the forward attaching fittings of the horizontal stabilizer and the top rib of the vertical stabilizer, and that inadequate torque values of some bolts were found. We are issuing this AD to prevent reduced structural integrity of the horizontal stabilizer, and consequent loss of controllability of the airplane.
Airworthiness Directives; Bombardier Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A and CL-601-3R) Airplanes
Document Number: 05-24244

Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A and CL-601-3R) airplanes. This AD requires measuring to detect migration of the lower gimbal pin and inspecting for other discrepancies of the horizontal stabilizer trim actuator (HSTA). This AD also requires replacing or modifying the HSTA, as applicable. This AD results from reports of failure of the lower gimbal pin of the HSTA. We are issuing this AD to prevent migration of the lower gimbal pin of the HSTA, which could result in loss of the horizontal stabilizer and consequent loss of control of the airplane.
