Federal Aviation Administration 2008 – Federal Register Recent Federal Regulation Documents

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:

We are adopting a new airworthiness directive (AD) for various transport category airplanes. This AD requires deactivation of Southeast Aero-Tek, Inc., auxiliary fuel tanks. This AD results from fuel system reviews conducted by the manufacturer, which identified potential unsafe conditions for which the manufacturer has not provided corrective actions. We are issuing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.

We are adopting a new airworthiness directive (AD) for certain Boeing Model 727-200 series airplanes. This AD requires deactivating auxiliary fuel tank systems installed in accordance with Supplemental Type Certificate (STC) SA1350NM. This AD results from fuel tank system reviews conducted by the manufacturer that identified potential unsafe conditions for which the manufacturer has not provided corrective actions. We are issuing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.

This action established Class E airspace at Hinton, OK. New Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures (SIAPs) at Hinton Muni Airport has made this action necessary. The FAA is proposing this action to enhance the safety and management of Instrument Flight Rules (IFR) aircraft operations at Hinton Muni Airport, OK.

The FAA is superseding an existing airworthiness directive (AD) for certain Turbomeca Arriel 1B, 1D, 1D1, and 1S1 turboshaft engines. That AD currently requires initial and repetitive position checks of the gas generator 2nd stage turbine blades on all Turbomeca Arriel 1B, 1D, 1D1, and 1S1 turboshaft engines. That AD also currently requires initial and repetitive replacements of 2nd stage turbines on 1B, 1D, and 1D1 engines only. This AD requires adding a 3,000 hour life limit to Arriel 1B 2nd stage turbine blades. This AD results from reports of failures of second stage turbine blades. We are issuing this AD to prevent failures of the 2nd stage turbine blades, which could result in uncommanded in-flight engine shutdown, and subsequent forced autorotation landing or accident.

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Bombardier Model DHC-8-400 series airplanes. The existing AD currently requires inspecting all barrel nuts to determine if the barrel nuts have a certain marking, inspecting affected bolts to determine if the bolts are pre-loaded correctly, and replacing all hardware if the pre-load is incorrect. For airplanes on which the pre-load is correct, the existing AD requires doing repetitive visual inspections for cracking of the barrel nuts and cradles and replacing all hardware for all cracked barrel nuts. The existing AD also requires replacement of all hardware for certain affected barrel nuts that do not have cracking, which would end the repetitive inspections for those airplanes. The existing AD also provides an optional replacement for all affected barrel nuts. This proposed AD would require replacement of all affected barrel nuts. This proposed AD results from reports of cracking in the barrel nuts at the four primary front spar wing-to-fuselage attachment joints. We are proposing this AD to detect and correct cracking of the barrel nuts at the wing front spar wing-to-fuselage joints, which could result in reduced structural integrity of the wing-to-fuselage attachments and consequent detachment of the wing.

We propose to adopt a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Model 390 airplanes. This proposed AD would require you to repetitively do a post-flight check (owner/operator holding at least a private pilot certificate checking for residual heat in the angle-of-attack (AOA) probes or an appropriately-rated mechanic doing a maintenance manual operational test of the heat of the AOA probes) after every flight and replace or modify (upload software) the stall warning AOA transmitters. This proposed AD results from reports of the potential for unannunciated loss of the heating function in the left-hand (LH) and right-hand (RH) stall warning AOA transmitters of Model 390 airplanes. We are proposing this AD to correct potentially inadequate stall warning with loss of stick pusher function.

We are adopting a new airworthiness directive (AD) for all Boeing Model 737-300, -400, and -500 series airplanes. This AD requires repetitive inspections of the downstop assemblies on the main tracks of the No. 2, 3, 4, and 5 slats and the inboard track of the No. 1 and 6 slats to verify if any parts are missing, damaged, or in the wrong order. This AD also requires other specified actions, and related investigative and corrective actions if necessary. This AD results from reports of fuel leaking from a puncture in the slat track housing (referred to as the ``slat can''). We are issuing this AD to detect and correct loose or missing parts from the main slat track downstop assemblies, which could puncture the slat can and result in a fuel leak and consequent fire.

We are adopting a new airworthiness directive (AD) for certain Goodrich evacuation systems approved under Technical Standard Orders (TSOs) TSO-C69, TSO-C69a, TSO-C69b, and TSO-C69c, installed on certain Boeing, McDonnell Douglas, and Airbus transport category airplanes. For certain systems, this AD requires replacing the evacuation system's shear-pin restraints with new ones. For certain other systems, this AD requires an inspection for manufacturing lot numbers; and a general visual inspection of the shear-pin restraint for discrepancies, and corrective actions if necessary. This AD results from several reports of corroded shear-pin restraints that prevented Goodrich evacuation systems from deploying properly. We are issuing this AD to prevent failure of an evacuation system, which could impede an emergency evacuation and increase the chance of injury to passengers and flightcrew during the evacuation.

This action establishes Class E Airspace at Lady Lake, FL to support a new Area Navigation (RNAV) Global Positioning System (GPS) Special Instrument Approach Procedure (IAP) that has been developed for medical flight operations into the Village of Homewood Lady Lake Hospital. This action enhances the safety and management of Instrument Flight Rule (IFR) operations by providing that required controlled airspace for this approach around Lady Lake, FL.

This action establishes Class E Airspace at Milford, PA to support a new Area Navigation (RNAV) Global Positioning System (GPS) Special Instrument Approach Procedure (IAP) that has been developed for medical flight operations into the Myer Airport. This action enhances the safety and management of Instrument Flight Rule (IFR) operations by providing that required controlled airspace to protect for this approach around Milford, PA.

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 the random and representative sampling of Flight Attendants currently employed by U.S. air carriers. The goal of this effort is to identify the type of fatigue that flight attendants experience, the frequency with which they experience fatigue, and the consequences fatigue may have on the safety of U.S. air carriers.

A direct final rule, published in the Federal Register February 4, 2008, (73 FR 6424), Docket No. FAA-2008-026, establishing Class E airspace at Hendricks County-Gordon Graham Field Airport, Indianapolis, IN, is being withdrawn. The FAA has found that Class E airspace already exists for the Indianapolis, IN, area, and therefore, substantial corrections would need to be made. In the interest of clarity, this rule is being withdrawn, and a new rulemaking amending the existing airspace will be forthcoming.

A direct final rule, published in the Federal Register February 11, 2008 (73 FR 7667) FAA Docket No. 2008-0003, is being withdrawn. This copy of the rule was inadvertently sent to the Federal Register. The direct final rule establishing Class E airspace at Muldrow Army Heliport, Lexington, OK, published February 15, 2008, (73 FR 8795) is the correct rule.

We propose to adopt a new airworthiness directive (AD) for the specified helicopters. This proposed AD results from a mandatory continuing airworthiness information (MCAI) AD originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The European Aviation Safety Agency (EASA), the Technical Agent for Italy, with which we have a bilateral agreement, states in the MCAI:

This notice announces the Office of Management and Budget's (OMB) approval of the information collection requirement for Special Federal Aviation Regulation (SFAR) No. 108, which was published on February 6, 2008.

We are adopting a new airworthiness directive (AD) for certain Boeing Model 737-300, -400, and -500 series airplanes. This AD requires an inspection to determine the manufacturer and manufacture date of the oxygen masks in the passenger service unit and the lavatory and attendant box assemblies, corrective action if necessary, and other specified action. This AD results from a report that several passenger masks with broken in-line flow indicators were found following a mask deployment. We are issuing this AD to prevent the in-line flow indicators of the passenger oxygen masks from fracturing and separating, which could inhibit oxygen flow to the masks and consequently result in exposure of the passengers and cabin attendants to hypoxia following a depressurization event.
