Federal Aviation Administration November 17, 2015 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; General Electric Company Turbofan Engines
Document Number: 2015-28898
Type: Proposed Rule
Date: 2015-11-17
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all General Electric Company (GE) CF6-80E1 turbofan engines with rotating compressor discharge pressure (CDP) seal, part number (P/N) 1669M73P02, installed. This proposed AD was prompted by reports from the manufacturer of cracks in the teeth of two rotating CDP seals found during engine shop visits. This proposed AD would require stripping of the coating, inspecting, and recoating the teeth of the affected rotating CDP seals. We are proposing this AD to prevent cracking of the CDP seal teeth, which can lead to uncontained part release, damage to the engine, and damage to the airplane.
Airworthiness Directives; Airbus Airplanes
Document Number: 2015-28892
Type: Proposed Rule
Date: 2015-11-17
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 99-16-01, for certain Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). AD 99-16-01 currently requires repetitive inspections of certain bolt holes where parts of the main landing gear (MLG) are attached to the wing rear spar, and repair if necessary. Since we issued AD-99-16-01, we have determined that the risk of cracking in the rear spar is higher than initially determined. This proposed AD would add airplanes to the applicability, reduce the compliance times and repetitive intervals for the inspections, and change the inspection procedures. We are proposing this AD to detect and correct cracking of the rear spar of the wing, which could result in reduced structural integrity of the airplane.
Airworthiness Directives; Bombardier, Inc. Airplanes
Document Number: 2015-28885
Type: Proposed Rule
Date: 2015-11-17
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This proposed AD was prompted by the discovery of a number of incorrectly calibrated angle of attack (AOA) transducers installed in the stall protection system. This proposed AD would require replacement of incorrectly calibrated AOA transducers. We are proposing this AD to detect and replace incorrectly calibrated AOA transducers; incorrect calibration of the transducers could result in late activation of the stick pusher.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2015-28882
Type: Proposed Rule
Date: 2015-11-17
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This proposed AD was prompted by a report that certain center and outboard stowage bin modules were incorrectly installed. This proposed AD would require an inspection of the center and outboard stowage bin modules for missing parts, quick release pins that are not fully engaged, and parts that are installed in incorrect locations; and corrective actions if necessary. We are proposing this AD to detect and correct incorrectly installed center and outboard stowage bin modules that might not remain intact during an emergency landing, resulting in injuries to occupants and interference with airplane evacuation.
Airworthiness Directives; Bombardier, Inc. Airplanes
Document Number: 2015-28822
Type: Rule
Date: 2015-11-17
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-100-1A10 (Challenger 300) airplanes. This AD was prompted by multiple reports of chafing found on an electrical wiring harness in the aft equipment bay, caused by contact between the wiring harness and a neighboring hydraulic line. This AD requires an inspection, repair if necessary, and modification of the wiring harness installation to ensure that the wiring harness routing is correct and a minimum clearance between the wire and the hydraulic line is maintained. We are issuing this AD to detect and correct chafing on an electrical wiring harness, which could cause an electrical short circuit or lead to a malfunction of the flight control system, the engine indication system, or the hydraulic power control system; and adversely affect the continued safe operation and landing of the airplane.
