Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP Airplanes
Document Number: E6-1420
Type: Proposed Rule
Date: 2006-02-02
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain EMBRAER Model EMB-145, -145ER, -145MR, -145LR, -145XR, - 145MP, and -145EP airplanes. This proposed AD would require modifying the routing of wire harness W407 near the fire extinguishing tube in the area of each engine, and installing new supports for related wiring. This proposed AD results from reports of chafing of wire harness W407 against the supports and nacelle structure in the engine area. We are proposing this AD to prevent such chafing, which could result in an engine shutting down during flight.
Airworthiness Directives; Boeing Model 767 Airplanes
Document Number: E6-1419
Type: Proposed Rule
Date: 2006-02-02
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for all Boeing Model 767 airplanes. This proposed AD would require repetitive inspections for cracking in the skin, the bulkhead outer chord, and the strap of the bulkhead outer chord at station (STA) 1725.5; and repair if necessary. This proposed AD also provides for repairs, which are optional for airplanes on which no cracking is found, that terminate certain inspections. This proposed AD results from reports of cracking in the skin panel common to stringer 7R and aft of the STA 1725.5 butt splice, and in the strap of the bulkhead outer chord at STA 1725.5. We are proposing this AD to detect and correct cracking in the skin, the bulkhead outer chord, or the strap of the bulkhead outer chord in this area, which could progress into surrounding areas and result in reduced structural integrity of the support structure for the vertical or horizontal stabilizer and subsequent loss of control of the airplane.
Airworthiness Directives; Airbus Model A300 B4-600R and A300 F4-600R Series Airplanes
Document Number: E6-1418
Type: Proposed Rule
Date: 2006-02-02
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Airbus Model A300 B4-600R and A300 F4-600R series airplanes. The existing AD requires repetitive inspections for damage of the center tank fuel pumps and fuel pump canisters and replacement of any damaged parts, and mandates modification of the canisters of the center tank fuel pumps, which terminates the repetitive inspections. For certain airplanes, this proposed AD would require a one-time inspection of the attachment bolts of the outlet flange of the canisters of the center tank fuel pumps for bolts that are too short and do not protrude through the nut, and replacement of the bolts if necessary. This proposed AD results from several reports that the attachment bolts for the canisters, modified by the requirements in the existing AD, are too short and do not fully protrude from the nuts. We are proposing this AD to prevent damage to the fuel pump and fuel pump canister, which could result in loss of flame trap capability and could provide a fuel ignition source in the center fuel tank.
Airworthiness Directives; Boeing Model 757-200 and -300 Series Airplanes
Document Number: E6-1415
Type: Proposed Rule
Date: 2006-02-02
Agency: Federal Aviation Administration, Department of Transportation
The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD) for certain Boeing Model 757-200 and -300 series airplanes. The proposed AD would have required inspecting for the part number, the serial number, and the mark ``RETESTED'' on the reaction link of the main landing gear (MLG), and replacing the reaction link of the MLG with a retested reaction link if necessary. Since the proposed AD was issued, we have received new data that all suspect reaction links of the MLG have been replaced with acceptable reaction links, and the suspect reaction links have been sent back to the reaction link manufacturer. Accordingly, the proposed AD is withdrawn.
Airworthiness Standards; Aircraft Engine Standards for Engine Life-Limited Parts
Document Number: 06-950
Type: Proposed Rule
Date: 2006-02-02
Agency: Federal Aviation Administration, Department of Transportation
The FAA is proposing to amend the certification standards for original and amended type certificates for aircraft engines by modifying the standards for engine life-limited parts. The proposed rule would establish new and uniform standards for the design and testing of life-limited parts for aircraft engines certificated by the FAA, the European Aviation Safety Agency (EASA), and the Joint Aviation Authorities (JAA). Additionally, the proposal would add new standards for the design of reciprocating engine turbocharger rotors. The proposed rule would harmonize part 33 requirements with EASA and JAA requirements.
Airworthiness Directives; Raytheon Aircraft Company Model 390 Airplanes
Document Number: 06-921
Type: Rule
Date: 2006-02-02
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain Raytheon Aircraft Company Model 390 airplanes. This AD contains the same information as emergency AD 2006-02-51 and publishes the action in the Federal Register. This AD requires you to visually inspect the hydraulic tube assembly (P/N 390-580035-0001 or P/N 390- 580035-0005) and the clamp (P/N MS21919WCJ6 or P/N MS21919WCJ7) (or FAA-approved equivalent part numbers), as specified in the service information; replace the clamp at each inspection; replace the hydraulic tube assembly immediately if any of the problems identified in the service bulletin are found; and report the results of each inspection or replacement to the FAA. This AD results from failure of the hydraulic tube assembly, which caused in-flight loss of hydraulic fluid. We are issuing this AD to prevent failure of the hydraulic tube assembly and consequent leaking of hydraulic fluid. This failure could result in loss of hydraulic system functions and risk of fire because of flammable fluid leakage in the engine nacelle and lead to loss of control of the airplane.
Airworthiness Directives; Glaser-Dirks Flugzeugbau GmbH Models DG-100 and DG-400 Sailplanes and DG Flugzeugbau GmbH Models DG-500 Elan Series and DG-500M Sailplanes
Document Number: 06-735
Type: Rule
Date: 2006-02-02
Agency: Federal Aviation Administration, Department of Transportation
The FAA adopts a new airworthiness directive (AD) for all Glaser-Dirks Flugzeugbau GmbH Models DG-100 and DG-400 sailplanes and certain DG Flugzeugbau GmbH Models DG-500 Elan Series and DG-500M sailplanes. This AD requires you to modify or replace the complete rudder mount assembly and ensure that the securing washer, castellated nut, and new split pins are installed. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to prevent the universal bearing of the lower rudder mounting from slipping out of the bearing support. The universal bearing slipping out could result in the rudder separating from its support. This failure could lead to loss of sailplane control during flight operations.
