Airworthiness Directives; Burkhart Grob Model G 103 C Twin III SL Sailplanes
The FAA proposes to supersede Airworthiness Directive (AD) 97- 24-09, which applies to Burkhart Grob Model G 103 C Twin III SL sailplanes. AD 97-24-09 currently requires repetitively inspecting the propeller bearing and upper pulley wheel for increased play and, if increased play is found, modifying the propeller bearing and pulley wheel. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this proposed AD to prevent loss of the sailplane propeller caused by increased play in the current design propeller bearing and upper pulley wheel. This could result in loss of control of the sailplane.
Airworthiness Directives; General Electric Company CT64-820-4 Turboprop Engines
The FAA is adopting a new airworthiness directive (AD) for General Electric Company (GE) CT64-820-4 turboprop engines with stage 1 turbine disk and shaft, part number (P/N) 6004T47P03 or 4921T10P02 installed. This AD requires removing from service these stage 1 turbine disk and shafts at reduced compliance times. This AD results from the discovery by the manufacturer of low-cycle-fatigue (LCF) cracks found in stage 1 turbine disk and shafts, P/Ns 6004T47P03 and 4921T10P02. We are issuing this AD to prevent uncontained failure of the stage 1 turbine disk and shaft, resulting in damage to the airplane.
Airworthiness Directives; Rockwell International (Aircraft Specification No. A-2-575 previously held by North American and recently purchased by Boeing) Models AT-6 (SNJ-2), AT-6A (SNJ-3), AT-6B, AT-6C (SNJ-4), AT-6D (SNJ-5), AT-6F (SNJ-6), BC-1A, SNJ-7, and T-6G Airplanes; and Autair Ltd. (Aircraft Specification No. AR-11 previously held by Noorduyn Aviation Ltd.) Model Harvard (Army AT-16) Airplanes
The FAA is adopting a new airworthiness directive (AD) for Rockwell International (Aircraft Specification No. A-2-575 previously held by North American and recently purchased by Boeing) Models AT-6 (SNJ-2), AT-6A (SNJ-3), AT-6B, AT-6C (SNJ-4), AT-6D (SNJ-5), AT-6F (SNJ-6), BC-1A, SNJ-7, and T-6G airplanes; and Autair Ltd. (Aircraft Specification No. AR-11 previously held by Noorduyn Aviation Ltd.) Model Harvard (Army AT-16) airplanes. This AD contains the same information as emergency AD 2005-12-51 and publishes the action in the Federal Register. It requires immediate and repetitive inspections of the inboard and outboard, upper and lower wing attach angles (except for the nose angles) of both wings for fatigue cracks; and, if any crack is found, replacement of the cracked angle with a new angle. This AD is the result of a report of a Rockwell International Model SNJ-6 (AT-6F) airplane crash that occurred on May 9, 2005, resulting in two fatalities. We are issuing this AD to detect and correct any fatigue crack in the inboard and outboard, upper and lower wing attach angles (except for the nose angles) of either wing, which could result in failure of the wing. This failure could lead to loss of control of the aircraft.
Airworthiness Directives; The Cessna Aircraft Company Models 208 and 208B Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all The Cessna Aircraft Company (Cessna) Models 208 and 208B airplanes. This proposed AD would require you to install a pilot assist handle, Cessna part number SK208-146-2, for all affected airplanes, install deicing boots on landing gear struts and cargo pod on certain Cessna Models 208 and 208B airplanes, and make changes to the Pilot's Operating Handbook (POH) and FAA-approved Airplane Flight Manual (AFM), and to the POH and AFM Supplement S1 for all affected airplanes. This proposed AD results from reports of several accidents and of problematic events involving the affected airplanes during operations in icing conditions, including nine events in the 2004-2005 icing season, and ground icing conditions. We are issuing this proposed AD to prevent ice adhering to critical surfaces. Ice adhering to critical surfaces could result in a reduction in airplane performance with the consequences that the airplane cannot perform a safe takeoff, climb, or maintain altitude.
Special Conditions: AMSAFE, Incorporated; Adam Aircraft Industries Model A500; Inflatable Four-Point Restraint Safety Belt With an Integrated Airbag Device
These special conditions are issued to AMSAFE, Inc. for the installation of an AMSAFE, Inc., Inflatable Four-Point Restraint Safety Belt with an Integrated Airbag Device on the Adam Model A500. These airplanes, as modified by the installation of this Inflatable Safety Belt, will have novel and unusual design features associated with the upper-torso restraint portions of the four-point safety belt, which contains an integrated airbag device. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Advisory Circular on Standard Airworthiness Compliance Checklists for Part 23 Projects
This notice announces a Federal Aviation Administration (FAA) proposed advisory circular that provides a standard compliance checklist for Title 14 of the Code of Federal Regulations (14 CFR) part 23 Type Certificate, Amended Type Certificate, and Supplemental Type Certificate projects. This checklist shows the typical methods of compliance with the regulations and provides a cross-reference to other related guidance material. The checklists created using the information in this AC complement the guidance in the Guides for Certification of Part 23 Airplanes (ACs 23-8B, 23-16A, 23-17B, and 23-19) and other more project specific guidance. This checklist is a starting place when applying for certification. This AC describes an acceptable means, but not the only means, of compliance with 14 CFR part 23. The material in this AC is neither mandatory nor regulatory in nature and does not constitute a regulation.

RTCA Special Committee 189/EUROCAE Working Group 53: Air Traffic Services (ATS) Safety and Interoperability Requirements
The FAA is issuing this notice to advise the public of a meeting of RTCA Special Committee 189/EUROCAE Working Group 53: Air Traffic Services (ATS) Safety and Interoperability Requirements.
Airworthiness Directives; BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ airplanes. This AD requires modifying the auxiliary power unit (APU) exhaust duct in the environmental control system (ECS) bay; installing new, improved insulation on this APU exhaust duct; and replacing the existing drain pipe with a new exhaust drain pipe blank. This AD is prompted by a determination that the temperature of the skin of the APU exhaust duct in the ECS bay is higher than the certificated maximum temperature for this area. We are issuing this AD to prevent the potential for ignition of fuel or hydraulic fluid, which could leak from pipes running through the ECS bay. Ignition of these flammable fluids could result in a fire in the ECS bay.
Airworthiness Directives; Avcraft Dornier Model 328-100 and -300 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Avcraft Dornier Model 328-100 and -300 airplanes. This AD requires a pressure test and detailed inspection of each fuselage drain line to determine if there is a blockage, and related investigative/ corrective actions if necessary. This AD is prompted by a report of leakage at one of the drain lines in the fuselage. We are issuing this AD to prevent blockage within the drain lines, causing fluids to collect. These fluids may freeze and expand, damaging the drain lines, and allowing fuel to leak into the cabin and fuel vapors to come into contact with ignition sources, which could result in consequent fire in the cabin.
Airworthiness Directives; AvCraft Dornier Model 328-100 and -300 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain AvCraft Dornier Model 328-100 and -300 airplanes. This AD requires operators to install colored identification strips on the pulley brackets, fairlead bracket assemblies, operational assemblies, and flight control cables. This AD is prompted by a report that the flight control systems do not have elements that are distinctively identified. We are issuing this AD to prevent the incorrect re-assembly of the flight control system during maintenance, which could result in reduced controllability of the airplane.
