Federal Aviation Administration 2010 – Federal Register Recent Federal Regulation Documents

We are adopting a new airworthiness directive (AD) for the products listed above. This 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 superseding an existing airworthiness directive (AD) for the products listed above. This 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:

The FAA is correcting an airworthiness directive (AD) that has published in the Federal Register. That AD applies to the products listed above. The reissue date of September 24, 1986, of the MU-2B-60 airplane flight manual (AFM) in table 3 of the Compliance section (e)(1)(i) is incorrect, in that it is ``September 24, 1985,'' instead of ``September 24, 1986.'' This document corrects this error. In all other respects, the original document remains the same.

The FAA proposes to adopt a new airworthiness directive (AD) for International Aero Engines (IAE) V2500-A1, V2522-A5, V2524-A5, V2525-D5, V2527-A5, V2527E-A5, V2527M-A5, V2528-D5, V2530-A5, and V2533-A5 turbofan engines. This proposed AD would require initial and repetitive 360[deg] borescope inspections of high-pressure turbine (HPT) stage 1 blade outer air seal segments for evidence of certain distress conditions. This proposed AD would also require incorporation of improved durability stage 1 blade outer air seal segments at the next exposure to the HPT module subassembly, as terminating action to the repetitive inspections. This proposed AD results from three reports received of HPT case burn-through events, numerous shop reports of loss of stage 1 blade outer air seal segments, and HPT case bulging. We are proposing this AD to prevent HPT case burn-through, uncontrolled under- cowl engine fire, and damage to the airplane.

We propose to adopt a new airworthiness directive (AD) for the products listed above.

This notice contains a summary of a petition seeking relief from specified requirements of 14 CFR. The purpose of this notice is to improve the public's awareness of, and participation in, this aspect of FAA's regulatory activities. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of the petition or its final disposition.

The FAA is issuing this notice to advise the public of a meeting of Joint RTCA Special Committee 213: EUROCAE WG-79: Enhanced Flight Vision Systems/Synthetic Vision Systems (EFVS/SVS).

This action proposes to revise Class E airspace at Wiley Post/ Will Rogers Memorial Airport in Barrow, AK, in order to accommodate the amendment of five Standard Instrument Approach Procedures (SIAPs), and one Obstacle Departure Procedure (ODP) and to enhance safety and management of Instrument Flight Rules (IFR) operations.

We are revising an earlier proposed airworthiness directive (AD) for certain Model 747 airplanes. The original NPRM would have required measuring the electrical bond resistance between the motor operated valve (MOV) actuators and airplane structure for the main, center, auxiliary, and horizontal stabilizer fuel tanks, as applicable, and corrective action if necessary. The original NPRM also would have required a revision to the maintenance program to incorporate airworthiness limitation (AWL) No. 28-AWL-21 or AWL No. 28-AWL-27, as applicable. The original NPRM resulted from fuel system reviews conducted by the manufacturer. This supplemental NPRM would revise the original NPRM by adding airplanes to the applicability, and would require replacing production-installed laminate phenolic spacers with metallic spacers between the fuel jettison MOV and the airplane structure, as applicable. We are proposing this supplemental NPRM to prevent electrical current from flowing through an MOV actuator into a fuel tank, which could create a potential ignition source inside the fuel tank. This condition, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

This amendment supersedes an existing airworthiness directive (AD) for Sikorsky Model S-92A helicopters that currently requires cleaning and inspecting each main gearbox (MGB) assembly mounting foot pad and rib for a crack and corrosion. If you do not find a crack, the AD requires applying a corrosion preventive compound. If you find a crack, the AD requires replacing the MGB before further flight. If you find corrosion, bubbled paint, or paint discoloration, the AD requires you to repair the MGB before further flight. This amendment retains the current requirements and expands the applicability to include another part-numbered MGB assembly and MGB housing. This amendment is prompted by the need to expand the applicability to include another MGB assembly and MGB housing that is prone to the same cracks and corrosion as the MGB listed in the current AD. The actions specified by this AD are intended to prevent the loss of the MGB and subsequent loss of control of the helicopter.

This notice contains a summary of a petition seeking relief from specified requirements of 14 CFR. The purpose of this notice is to improve the public's awareness of, and participation in, this aspect of FAA's regulatory activities. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of the petition or its final disposition.

This action would require a person to carry a pilot certificate with photo to exercise the privileges of the pilot certificate. This proposal responds to section 4022 of the Intelligence Reform and Terrorism Prevention Act (IRTPA). The FAA previously required all pilots to obtain a plastic certificate (excepting temporary certificates and student pilot certificates). This proposal furthers the fulfillment of IRTPA by requiring a photo of the pilot to be on all pilot certificates. The FAA also proposes to require student pilots to obtain a plastic certificate with photo. Student pilot certificates would also have the same duration as other pilot certificates. Additionally, because of the new photo requirements, this proposal modifies the application process and the fee structure for pilot certificates.

These special conditions are issued for the Bombardier Inc. Model CL-600-2E25 airplane. This airplane will have a novel or unusual design feature associated with the rudder-traveler limiting system controlling the command-by-wire (CBW) rudder. This system can serve to alleviate loads in the airframe but, in a failure state, can create loads in the airframe. 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.

We are revising an earlier proposed airworthiness directive (AD) for the products listed above. That NPRM proposed a one-time inspection to detect damage of the wire assemblies of the tail tank fuel system, a wiring change, and corrective actions if necessary. That NPRM was prompted by fuel system reviews conducted by the manufacturer. This action revises that NPRM by adding, for certain airplanes, a general visual inspection for correct installation of the self- adhering, high-temperature electrical insulation tape; installation of a wire assembly support bracket and routing wire assembly; changing wire supports; and installation of a wire protection bracket. We are proposing this supplemental NPRM to detect and correct a potential of ignition sources inside fuel tanks, which, in combination with flammable vapors, could result in a fuel tank fire or explosion, and consequent loss of the airplane.

This amendment adopts a new airworthiness directive (AD) for the Sikorsky Model S-70A and S-70C helicopters. This AD requires an ultrasonic test (UT) inspection of the tail gearbox output bevel gear (gear) for a crack. If you find a crack, replacing the gear with an airworthy gear is required before further flight. This AD is prompted by three gear cracking incidents, one of which resulted in the tail rotor separating from the helicopter. The actions specified by this AD are intended to detect a crack in the gear to prevent a tail rotor separating, loss of tail rotor control, and subsequent loss of control of the helicopter.

We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires inspecting certain serial number (S/N) gas generator turbine (GGT) shafts for nonconforming land balance-cuts, and if found, removing the shaft from service. This AD was prompted by reports of a manufacturing quality problem. We are issuing this AD to detect nonconforming GGT shaft land balance-cuts, which could result in the shaft failing before its published life limit, and which could result in an uncontained engine failure and damage to the airplane.

We are adopting a new airworthiness directive (AD) for certain Model 777-200, -200LR, -300, and -300ER series airplanes. This AD requires removing and repairing the sealant at the four lower corners of the wing center section and the four lower t-chord segment gaps on each side of the wing center section. This AD results from reports of fuel leakage from the center tank. We are issuing this AD to detect and correct improperly applied sealant, which could result in the disbonding and displacing of sealant, and consequent fuel leaks. On the ground, uncontained fuel leakage could result in pooling, and pooling combined with an ignition source could result in a fire.

We are adopting a new airworthiness directive (AD) for the products listed above. This 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:

The Federal Aviation Administration (FAA) proposes to rule and invites public comment on the application for a release of approximately 2,000 square feet of airport property at Tucson International Airport, Tucson, Arizona, from all conditions contained in the Grant Assurances since the parcel of land is not needed for airport purposes. The property will be sold for its fair market value and the proceeds deposited in the airport account. The reuse of the land for commercial purposes represents a compatible land use that will not interfere with the airport or its operation. The interest of civil aviation continues to be served by the release.

The FAA is correcting an airworthiness directive (AD) that was published in the Federal Register. That AD applies to the products listed above. In the Information Heading and in the SUMMARY section of the published AD, we incorrectly included Cessna 188 series airplanes. In the Unsafe Condition section, we incorrectly designated that paragraph as (e) instead of (d). Also in the Compliance section, paragraph (f)(2), and in Figure 1, we incorrectly stated the mailing address for the report. We are issuing this document to help eliminate any confusion that this AD may have created in the Information Heading and in the SUMMARY and Unsafe Condition sections. This document corrects those errors. In all other respects, the original document remains the same.

This document publishes in the Federal Register an amendment adopting Emergency Airworthiness Directive (AD) 2010-18-52 which was sent previously to all known owners and operators of MD Helicopters, Inc. (MDHI) Model MD900 helicopters by individual letters. This AD requires visually inspecting the main rotor hub (hub) for a crack. If a crack is found, this AD requires, before further flight, replacing the unairworthy hub with an airworthy hub. Additionally, if a cracked hub is found, this AD requires reporting the finding to the Los Angeles Aircraft Certification Office within 10 days of finding the crack. This AD is prompted by two reports of cracks detected in the hub in the area near the flex beam bolt hole locations during maintenance on two MDHI Model MD900 helicopters. The actions specified by this AD are intended to detect a crack in the hub and prevent failure of the hub and subsequent loss of control of the helicopter.

This action modifies the Charlotte, NC, Class B airspace area to ensure the containment of aircraft, accommodate the implementation of area navigation (RNAV) departure procedures, and support operations of the third parallel runway at Charlotte/Douglas International Airport. The FAA is taking this action to improve the flow of air traffic, enhance safety, and reduce the potential for midair collision in the Charlotte, NC, terminal area.

We propose to adopt a new airworthiness directive (AD) for certain Model 747-200B, -300, -400, -400D, and -400F series airplanes. This proposed AD would require an inspection to determine the part number of the door and to determine if the correct mid-pivot access door is installed, and the installation of a marker on the mid-pivot access door, and if necessary, repetitive ultrasonic inspections for cracking of the mid-pivot bolt assembly and eventual replacement of the mid-pivot bolt assembly. This proposed AD results from a report that the left and right spring beam mid-pivot bolt assembly access doors for the No. 1 strut were inadvertently installed in the incorrect position during strut modification. We are proposing this AD to detect and correct incorrectly installed mid-pivot bolt assemblies on the spring beam on the outboard struts. Incorrectly installed bolt assemblies could lead to fatigue cracking and consequent fracturing of the mid- pivot bolt assembly, which could lead to loss of the spring beam load path and the possible separation of a strut and engine from the airplane during flight.

We propose to rescind an airworthiness directive (AD) for the products listed above. The existing AD, AD 98-09-27, resulted from aircraft certification testing which revealed that stresses on the thrust reverser hinge were higher than had been anticipated during engine certification, and the United Kingdom Civil Aviation Authority, issuing AD 008-03-97. Since we issued AD 98-09-27, we discovered that its requirements were duplicated in airplane-level AD 2001-09-14, issued by the FAA Transport Airplane Directorate. This proposal to rescind the engine- level AD allows the public the opportunity to comment on the FAA's determination of the duplication of requirements in another AD, before we rescind the engine-level AD.

This rule establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
