Special Conditions: Eurocopter France (ECF) Model EC225LP Helicopter, Installation of a Search and Rescue (SAR) Automatic Flight Control System (AFCS)
These special conditions amend and supersede those final special conditions No. 29-022-SC, for the ECF model EC225LP helicopter, which were published in the Federal Register on November 6, 2008 (73 FR 65968). A notice proposing this amendment was published December 20, 2010 (75 FR 79312). This amendment modifies the original final special conditions to address comments received and to clarify the intent of some of the requirements. This helicopter, as modified by ECF, will have novel or unusual design features associated with installing an optional SAR AFCS. 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.
Public Notice for Waiver of Aeronautical Land-Use Assurance: Bolton Field Airport; Columbus, OH
The Federal Aviation Administration (FAA) is considering a proposal to change a portion of the Bolton Field Airport from aeronautical use to non-aeronautical use and to authorize the sale of the airport property. The proposal consists of the sale of unimproved land owned by the Columbus Regional Airport Authority (CRAA) for use as an office/warehouse/distribution facility. The CRAA has requested from FAA a ``Release from Federal agreement obligated land covenants'' to sell 60.282 acres of property acquired by the CRAA with Federal funding under Grant Number 8-39-0026-01. The above mentioned land is not needed for aeronautical use, as shown on the Airport Layout Plan. There are no impacts to the airport by allowing the CRAA to dispose of the property. Approval does not constitute a commitment by the FAA to financially assist in the disposal of the airport property nor a determination of eligibility for grant-in-aid funding from the FAA. The disposition of proceeds from the disposal of the airport property will be in accordance with FAA's Policy and Procedures Concerning the Use of Airport Revenue, published in the Federal Register on February 16, 1999. In accordance with section 47107(h) of title 49, United States Code, this notice is required to be published in the Federal Register 30 days before modifying the land-use assurance that requires the property to be used for an aeronautical purpose.
Airworthiness Directives; The Boeing Company Airplanes
We are superseding an existing airworthiness directive (AD) for certain The Boeing Company Model 747 airplanes. That AD currently requires repetitive visual inspections around the bushings of the wing landing gear (WLG) beam outboard end fittings for corrosion, and rework if necessary; and ultrasonic inspections for cracks of the outboard end fittings of the WLG support beams, and rework if necessary. This new AD adds airplanes and adds repetitive inspections of the outboard end fitting of the left and right WLG support beams for cracks and corrosion, and corrective actions if necessary. This AD was prompted by new reports of corrosion damage to the end fittings of the WLG support beams, and one report of subsequent cracking in the end fittings. We are issuing this AD to detect and correct corrosion and subsequent cracking in the outboard end fittings, which could result in separation of the fitting and damage to adjacent flight control cables and hydraulic systems and consequent reduced controllability of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-100, -200, and -200C series airplanes. This AD was prompted by a report of a severed upper butt strap, and cracks in the forward skin and bonded doubler, on one airplane. This AD requires repetitive inspections for cracks and a chemical spot test in the area of station (STA) 908, and related investigative and corrective actions, if necessary. For certain airplanes, this AD requires an inspection and modification. We are issuing this AD to prevent cracks at the adjacent mating skins (forward and aft), which could initiate just above stringers S-4R and S-4L; and could grow and result in a decompression event.
Airworthiness Directives; Alpha Aviation Concept Limited Airplanes
We are adopting a new airworthiness directive (AD) for Alpha Aviation Concept Limited Model R2160 Airplanes. 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 possible installation of non-conforming air filter elements that are not fitted with metallic mesh and could internally collapse resulting in disruption of the powerplant operation. We are issuing this AD to require actions to address the unsafe condition on these products.
