Clarification of Policy Regarding Approved Training Programs; Correction
The FAA is correcting a notice published on December 27, 2011 (76 FR 80831). In that notice of availability the FAA announced the availability of an FAA Notice that would require FAA inspectors to review policy regarding approved training programs as well as to identify and correct those training programs which erroneously issued credit for previous training or checking. The Notice also provided guidance on constructing reduced hour training programs based on previous experience. Upon review of the comments and any necessary revision, the Notice would cancel and replace FAA Order 8900.1, Volume 3, Chapter 19, Paragraph 3-1111. This document corrects an incorrect comment due date.
Airworthiness Directives; Eurocopter Deutschland GMBH Helicopters
We propose to adopt a new airworthiness directive (AD) for Eurocopter Deutschland GMBH (ECD) Model MBB-BK 117 C-1 and C-2 helicopters. This proposed AD would require installing a placard that corresponds to the maximum permissible flight altitude, amending the Rotorcraft Flight Manual (RFM) to revise the maximum permissible operating altitude, and inserting revised performance charts into the RFM. The proposed AD would also require a repetitive maintenance ``MAX N1 CHECK'' to determine the appropriate maximum altitudes. The AD would also require, if the engine or a fuel control unit (FCU) or module 2 or 3 is replaced, repeating the maintenance ``MAX N1 CHECK.'' Finally, the proposed AD specifies that modifying both engines would provide terminating action for the proposed AD requirements. This proposed AD is prompted by the failure of a ``few'' engines to reach the specified one-engine-inoperative (OEI) rating at altitudes above 10,000 feet. The proposed actions are intended to prevent flights at altitudes where the full OEI engine power cannot be reached and subsequent loss of control of the helicopter if an OEI operation is required.
Public Notice for Release of Aeronautical Property at New Castle Airport (ILG), New Castle, DE
The Federal Aviation Administration (FAA) is requesting public comment on the Delaware River and Bay Authority's (DRBA) request to grant the Delaware Department of Transportation a permanent easement on 2.424 +/- acres of airport property along portions of Old Churchman's Road bordering a portion of the Airport property perimeter for roadway improvements. The 2.424 +/- acres land covered by the purposed easement will no longer be dedicated for aviation use by the New Castle Airport. The DRBA, as operator of the New Castle Airport (ILG), has proposed the extension of Taxiway ``H'' and the development of an approximate thirty-eight (38) acre parcel of airport property on the southeasterly side of Old Churchman's Road for aviation related purposes. The Thirty- Eight Acre Parcel is currently undeveloped and separated from the main airport property by Old Churchman's Road. In order to gain connectivity and access to the Thirty-Eight Acre Parcel and allow for the extension of Taxiway ``H'' and future development, 0.610 +/- acres of Old Churchman's Road must be vacated by the Delaware Department of Transportation and returned to New Castle County as fee owner for aeronautical use. Once the 0.610+/- acres of Old Churchman's Road is vacated, future road improvements to include, but not limited to, the upgrade of Old Churchman's Road from Route 13 to the easterly boundary of the Thirty-Eight Acre Parcel, the construction of a public road connecting Old Churchman's Road and New Churchman's Road at the eastern boundary of the Thirty-Eight Acre Parcel, and the construction of certain improvements along New Churchman's Road can be made on the proposed 2.424 +/- acre easement area. This will allow Delaware Department of Transportation to bring portions of Old Churchman's Road up to standards and accommodate a new connector from Old Churchman's Road to New Churchman's Road. The 2.424 +/- acre parcel is located at New Castle Airport (ILG), New Castle, DE, situated northwesterly of Dupont Highway, U.S. Route 13 and northeasterly of New Churchman's Road, Delaware State Road 58, New Castle Hundred, New Castle County, Delaware. The parcel is comprised of several small, narrow, Right-of-Way easement ``strips'' totaling 2.424 +/- acres in aggregate and is generally located along Old Churchman's Road commencing at Route 13 and running in a westerly direction to the easterly property line of the Thirty-Eight Acre Parcel. The property is currently depicted on the Airport Layout Plan (ALP) of record as airport property and consists of five sections of narrow strips of land varying 1.272 acres to 0.054 acres. The strips of land are parts of Tax Parcel No. 10-018.00-006. These areas, totaling 2.424 +/-, acres are not required for aeronautical use and can be used for road improvements.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A330-200 series airplanes; Model A330-300 series airplanes, Model A340-200 series airplanes; Model A340-300 series airplanes; Model A340-541 airplanes; and Model A340-642 airplanes. This proposed AD was prompted by reports of cracks in the bogie pivot pin caused by material heating due to friction between the bogie pivot pin and bush. This proposed AD would require performing a detailed inspection for degradation of the bogie pivot pins and pivot pin bushes of the main and central landing gear for any cracks and damage, and repairing or replacing bogie pivot pins and pivot pin bushes, if necessary. We are proposing this AD to correct and detect cracks and damage to the main and central landing gear, which could result in the collapse of the landing gear and adversely affect the airplane's continued safe flight and landing.
Special Conditions: Learjet Inc., Learjet Model LJ-200-1A10; Interaction of Systems and Structures
These special conditions are issued for the Learjet Model LJ- 200-1A10 airplane. This airplane will have novel or unusual design features associated with systems that, directly or as a result of failure or malfunction, affect structural performance. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for these design features. 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.
