Airworthiness Directives; BAE Systems (Operations) Limited Model BAe 146 Airplanes
The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to certain BAE Systems (Operations) Limited Model BAe 146 airplanes. The original NPRM would have required repetitive inspections to measure the depth of chafing or scoring in the skin along the full length of the wing-to-fuselage fairing from forward to aft ends at the contact between the seal and fuselage, and related investigative/corrective actions if necessary. The original NPRM resulted from a report of chafing in this area. This action revises the original NPRM by removing certain credit for prior accomplishment of proposed requirements. We are proposing this supplemental NPRM to detect and correct such chafing or scoring, which could result in reduced structural integrity of the fuselage.
Airworthiness Directives; Boeing Model 727 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 727 airplanes. This proposed AD would require repetitive measurements of the freeplay of the left and right outboard aileron balance tabs and of the upper and lower rudder tabs, and related investigative/corrective actions if necessary. This proposed AD also would require repetitive lubrication of the hinge bearings and rod end bearings of the aileron balance tabs. This proposed AD results from reports of freeplay-induced vibration of the outboard aileron balance tab and rudder tab. We are proposing this AD to prevent excessive vibration of the airframe during flight, which could result in divergent flutter and loss of control of the airplane.
Airworthiness Directives: Rolls-Royce Deutschland (RRD) (Formerly Rolls-Royce plc) Tay 650-15 Series Turbofan Engines
This action withdraws a notice of proposed rulemaking (NPRM). That NPRM proposed a new airworthiness directive (AD) that applies to certain RRD Tay 650-15 series turbofan engines. That proposed action would have required initial and repetitive inspections of the high pressure compressor (HPC) shaft and high pressure turbine (HPT) shaft for spline flank wear. Since we issued that NPRM, the Luftfahrt- Bundesamt (LBA), which is the airworthiness authority for Germany, notified us that the spline flank wear inspections are now downgraded by RRD from ``mandatory'' to ``recommended''. Accordingly, we withdraw the proposed rule.
Airworthiness Directives; Rolls-Royce plc Model RB211 Trent 892, 884, 877, 875, and 892B Series Turbofan Engines
The FAA proposes to rescind an existing airworthiness directive (AD) for Rolls-Royce plc (RR) Model RB211 Trent 892, 884, 877, 875, and 892B series turbofan engines. That AD currently requires inspecting and replacing certain angle gearbox and intermediate gearbox hardware, and on-going repetitive inspections of the magnetic chip detectors. This action would rescind all the requirements of AD 97-06- 13, Amendment 39-9970, Docket No. 97-ANE-09. This proposed rescission results from the FAA determining that the inspections and replacements required by that AD are no longer required to correct an unsafe condition. Operators should, however, incorporate those inspections and replacements into their normal maintenance practices.
Proposed Revision of Class E Airspace; Huslia, AK
This action proposes to revise Class E airspace at Huslia, AK. One Standard Instrument Approach Procedure (SIAP) is being produced, and two SIAPs are being revised for the Huslia Airport. Adoption of this proposal would result in revision of Class E airspace upward from 700 feet (ft.) and 1,200 ft. above the surface at Huslia, AK.
Antidrug and Alcohol Misuse Prevention Programs for Personnel Engaged in Specified Aviation Activities
The FAA is delaying the compliance date for the final rule clarifying that contractors, including subcontractors at any tier, must be subject to drug and alcohol testing. This action is necessary because it has come to our attention that some original equipment manufacturers (OEMs) and other entities may be confused regarding whether they are performing maintenance or preventive maintenance duties subject to drug and alcohol testing, or manufacturing duties not subject to testing. The effective date of April 10, 2006, will remain the same, but this action extends the compliance date until October 10, 2006, which gives OEMs and others sufficient time to determine what work is subject to drug and alcohol testing.
Airworthiness Directives; Turbomeca Makila 1 A2 Turboshaft Engines
The FAA is adopting a new airworthiness directive (AD) for Turbomeca Makila 1 A2 turboshaft engines. This AD requires upgrading the software version of the digital electronic control. This AD results from Turbomeca determining that Makila 1 A2 turboshaft engines with software version 9 installed in the digital electronic control unit (DECU), under certain conditions, could experience a free turbine overspeed and uncontained failure. We are issuing this AD to prevent overspeed and uncontained failure of the free turbine and damage to the helicopter.
Airworthiness Directives; The Cessna Aircraft Company Models 208 and 208B Airplanes
This document makes a correction to Airworthiness Directive (AD) 2006-06-06, which published in the Federal Register on March 16, 2006 (71 FR 13533), and applies to all The Cessna Aircraft Company (Cessna) Models 208 and 208B airplanes. AD 2006-06-06 requires you to incorporate information into the applicable section of the Airplane Flight Manual (AFM) and Pilots Operating Handbook (POH) and requires installation of placards. Current language in paragraph (f)(3) of AD 2006-06-06 regarding the placard requirement inadvertently states: ``You may insert a copy of this AD into the appropriate sections of the POH to comply with this action.'' This does not meet the intent of the AD. This document corrects that paragraph by removing the language referenced above.
Establishment of Class E Airspace; Valdez Pioneer Field, AK
This action revises Class E airspace at Valdez Pioneer Field, AK to provide adequate controlled airspace to contain aircraft executing two new Standard Instrument Approach Procedures (SIAPs), and one revised SIAP. This rule results in revised Class E airspace extending upward from 1,200 feet (ft.) above the surface at Valdez Pioneer Field, AK.
Establishment of Class E Airspace; Minchumina, AK
This action establishes Class E airspace at Minchumina, AK to provide adequate controlled airspace to contain aircraft executing two new Standard Instrument Approach Procedures (SIAPs), and one revised SIAP. This rule results in new Class E airspace established upward from 700 feet (ft.) above the surface at Minchumina, AK.
Establishment of Class E Airspace; Cold Bay, AK
This action revises Class E airspace at Cold Bay, AK to provide adequate controlled airspace to contain aircraft executing two new Standard Instrument Approach Procedures (SIAPs), and seven revised SIAPs.

Notice Before Waiver With Respect to land at Hamilton Municipal Airport, Hamilton, NY
The FAA is publishing notice of the proposed release of approximately 3.0 acres of land located at Hamilton Municipal Airport, to allow its sale for non-aviation development. The parcel was part of the airport property acquired with federal funding support under the Airport Improvement Program. The Village of Hamilton proposes to sell the land to a developer who will develop it as a Medical office Building. FAA's action is to release the land from a deem provision requiring aeronautical use of the property. The Village of Hamilton has stated that it has no aeronautical use for the parcel now or in the near future according to the Hamilton Municipal Airport Layout Plan. The Fair Market Value of the land will be paid to the Village of Hamilton to be used for the capital development of Hamilton Municipal Airport. Any comments the agency receives will be considered as a part of the decision.
Establishment of Class E Airspace; St. Paul Island, AK
This action revises Class E airspace at St. Paul Island, AK to provide adequate controlled airspace to contain aircraft executing one new Standard Instrument Approach Procedure (SIAP), and five revised SIAPs. This rule results in revised Class E airspace extending upward from 700 feet (ft.) and 1,200 ft. above the surface at St. Paul Island, AK.
Standard Instrument Approach Procedures; Miscellaneous Amendments
This amendment amends Standard Instrument Approach Procedures (SIAPs) for operations at certain airports. These regulatory actions are needed because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, addition of new obstacles, or changes in 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.
