Airworthiness Directives; Boeing Model 757-200, -200CB, -200PF, and -300 Series Airplanes
Document Number: E7-13265
Type: Proposed Rule
Date: 2007-07-09
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for all Boeing Model 757-200, -200CB, -200PF, and -300 series airplanes. This proposed AD would require installation of an automatic shutoff system for the center tank fuel boost pumps, and installation of a placard in the airplane flight deck if necessary. This proposed AD would also require revisions to the Limitations and Normal Procedures sections of the airplane flight manual to advise the flightcrew of certain operating restrictions for airplanes equipped with an automated center tank fuel pump shutoff control. This proposed AD would also require a revision to the Airworthiness Limitations (AWLs) section of the Instructions for Continued Airworthiness to incorporate AWL No. 28- AWL-20 and No. 28-AWL-26. This proposed AD would also require replacement of the fuel control panel assembly with a modified part, installation of two secondary pump control relays for the center tank fuel pumps, other specified actions, and concurrent modification of the fuel control panel assembly. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent center tank fuel pump operation with continuous low pressure, which could lead to friction sparks or overheating in the fuel pump inlet or could create a potential ignition source inside the center fuel tank; these conditions, in combination with flammable fuel vapors, could result in a center fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747SR, and 747SP Series Airplanes
Document Number: E7-13263
Type: Proposed Rule
Date: 2007-07-09
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747SR, and 747SP series airplanes. This proposed AD would require repetitive inspections for cracking of the station (STA) 1241 bulkhead fittings just above the canted pressure deck; a one-time determination of the edge margin at seven fastener positions on each side of the airplane; and related investigative/ corrective actions if necessary. This proposed AD results from a report that an operator found a 1.65-inch crack on the STA 1241 bulkhead fitting on the left side of a Boeing Model 747-200F series airplane that had accumulated 17,332 total flight cycles. We are proposing this AD to detect and correct cracking in the STA 1241 bulkhead fittings, which could result in reduced structural integrity of the airplane.
Airworthiness Directives; International Aero Engines AG (IAE) V2500 Series Turbofan Engines
Document Number: E7-13256
Type: Proposed Rule
Date: 2007-07-09
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for IAE V2500-A1, V2522-A5, V2524-A5, V2527-A5, V2527E-A5, V2527M-A5, V2530-A5, V2533-A5, V2525-D5, V2528-D5 turbofan engines. This proposed AD would require removing certain No. 4 bearing seal components from service at the next shop visit or by an end date determined by the engine model. This proposed AD results from instances of oil loss from the No. 4 bearing compartment. We are proposing this AD to prevent heat damage to high pressure turbine (HPT) and low pressure turbine (LPT) critical life limited hardware such as the HPT stage 1-2 airseal. Damage to the HPT stage 1-2 airseal could cause uncontained engine failure and damage to the airplane.
Airworthiness Directives; Pacific Aerospace Corporation, Ltd Model 750XL Airplanes
Document Number: E7-13247
Type: Proposed Rule
Date: 2007-07-09
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: To prevent the cockpit door windows separating from their frames, * * * The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
Airworthiness Directives; Airbus Model A300-600 Series Airplanes
Document Number: E7-13211
Type: Proposed Rule
Date: 2007-07-09
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Notice of Intent To Request Approval From the Office of Management and Budget of a New Information Collection Activity, Request for Comments; 2008 Newly Certificated Airframe and/or Powerplant Mechanics: Assessment of the Mechanic's Practical Test Program
Document Number: 07-3314
Type: Notice
Date: 2007-07-09
Agency: Federal Aviation Administration, Department of Transportation
The FAA invites public comments about our intention to request the Office of Management and Budget (OMB) to approve a new information collection. This project involves collecting data from individual applicants who have recently taken, for the first time, and passed an oral and/or practical Airframe and/or Powerplant (A and/or P) Mechanic Certification test.
