Federal Aviation Administration April 15, 2014 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Bombardier, Inc. Airplanes
Document Number: 2014-08463
Type: Proposed Rule
Date: 2014-04-15
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B16 (CL-604 Variant) airplanes. This proposed AD was prompted by reports of loose, broken, or backed out spur gear bolts on the horizontal stabilizer trim actuator (HSTA). This proposed AD would require a revision to the airplane flight manual, a revision to the maintenance or inspection program, and replacement of HSTAs having certain part numbers. We are proposing this AD to detect and correct loose spur gear bolts on the HSTA, which, if combined with the failure of the primary load path, could lead to failure of the HSTA and subsequent loss of control of the airplane.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Airplanes
Document Number: 2014-08460
Type: Proposed Rule
Date: 2014-04-15
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB- 135BJ airplanes. This proposed AD was prompted by reports of failure of the bolts that connect the cockpit windshield center-post to the forward fuselage. This proposed AD would require repetitive detailed inspections to detect discrepancies on the attaching parts of the cockpit windshield center-post; checking whether the bolts are tightened, if applicable; and modifying parts, including inspecting for and repairing damage. The modification would terminate the repetitive inspections. We are proposing this AD to prevent failed bolts and failed attaching parts of the cockpit windshield center-post, which could lead to loss of structural integrity of the airplane.
