Airworthiness Directives; McDonnell Douglas Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-9-87 (MD-87), and MD-88 Airplanes
The FAA is adopting a new airworthiness directive (AD) for all McDonnell Douglas Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD- 83), DC-9-87 (MD-87), and MD-88 airplanes. This AD requires repetitive inspections to detect cracks in the horizontal stabilizer, and related investigative/corrective actions if necessary. This AD results from reports of cracks found in the horizontal stabilizerin the upper and lower aft skin panels at the aft inboard corner at station XH = 8.2, and in the rear spar upper caps adjacent to the aft skin panel at station XH = 10.0. We are issuing this AD to detect and correct cracks in the upper and lower aft skin panels and rear spar upper caps, which, if not corrected, could lead to the loss of overall structural integrity of the horizontal stabilizer.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 Airplanes and Model ERJ 190 Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all EMBRAER Model ERJ 170-100 LR, -100 STD, -100 SE, and -100 SU airplanes. The existing AD currently requires repetitively replacing the low-stage check valve and associated seals of the right-hand engine bleed system. This proposed AD adds new airplanes to that existing requirement. For all airplanes, this proposed AD would also require repetitively replacing the low-stage check valve and associated seals of the left-hand engine bleed system with a new check valve and new seals. This proposed AD results from a report that an engine shut down during flight due to the failure of the low-stage check valve to close. We are proposing this AD to prevent failure of the low-stage check valve, which could result in an engine shutting down during flight.
Air Traffic Procedures Advisory Committee
The FAA is issuing this notice to advise the public that a meeting of the Federal Aviation Air Traffic Procedures Advisory Committee (ATPAC) will be held to review present air traffic control procedures and practices for standardization, clarification, and upgrading of terminology and procedures.
Airworthiness Directives; Air Tractor, Inc. Model AT-602 Airplanes
We are adopting a new airworthiness directive (AD) for certain Air Tractor, Inc. (Air Tractor) Model AT-602 airplanes. This AD requires you to install access holes to do repetitive detailed visual inspections for cracks in the horizontal stabilizer brace tube assembly, and if any cracks are found as a result of a visual inspection, to replace the horizontal stabilizer brace tube assembly with a new design horizontal stabilizer brace tube assembly. The installation of the new design horizontal stabilizer brace tube assembly is terminating action for the repetitive inspection requirement. This AD results from two reports of Model AT-602 airplanes with cracked horizontal stabilizer brace tube assemblies. We are issuing this AD to detect and correct cracks in the horizontal stabilizer brace tube assembly, which could result in failure of the horizontal stabilizer. This failure could affect the ability to control pitch with consequent loss of control.
Establishment of Class D and E Airspace; Aguadilla, PR
This action establishes Class D and E4 airspace at Aguadilla, PR. A Federal contract tower with a weather reporting system has been constructed at Rafael Hernandez Airport. Therefore, the airport meets criteria for Class D and E4 airspace. Class D and E4 surface area airspace is required when the control tower is open to contain Standard Instrument Approach Procedures (SIAPs) and other Instrument Flight Rules (IFR) operations at the airport. This action establishes Class E and E4 airspace extending upward from the surface to and including 2,700 feet MSL within a 4.5-mile radius of the airport and within 2.4 miles each side of the Borinquen VORTAC 257[deg] radial extending from the 4.5 mile radius to 7 miles west of the VORTAC.
Establishment of Class E Airspace; Dean Memorial Airport, NH
This action establishes a Class E airspace area at Dean Memorial Airport, Haverhill, NH (K5B9) to provide for adequate controlled airspace for those aircraft using the new Area Navigation (RNAV) Instrument Approach Procedure to the Airport.
Amendment of Class E Airspace; Middlesboro, KY
This action amends Class E5 airspace at Middlesboro, KY. An Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedure (SIAP) A has been developed for MiddlesboroBell County Airport. As a result, additional controlled airspace extending upward from 700 feet Above Ground Level (AGL) is needed to contain the SIAP.
Notice of Availability of a Final Environment Assessment (Final EA) and a Finding of No Significant Impact/Record of Decision (FONSI/ROD) for the Proposed Runway 22R/4L Offset ILS at Detroit Metropolitan Wayne County Airport (DTW) Located in Romulus, Detroit
The Federal Aviation Administration (FAA) is issuing this notice to advise the public that it has prepared a Final Environmental Assessment (Final EA) for the Proposed Runway 22R/4L Offset ILS at Detroit Metropolitan Wayne County Airport and on April 27, 2007, it has approved a Finding of No Significant Impact/Record of Decision (FONSI/ ROD) based on this Final EA. The Federal Aviation Administration (FAA) prepared the Final EA in accordance with the National Environmental Policy Act and the Federal Aviation Administration's regulations and guidelines for environmental documents. The Final EA was reviewed and evaluated by the FAA, and was accepted on April 27, 2007 as a Federal document by the FAA's Responsible Federal Official.
