Department of Transportation February 28, 2006 – Federal Register Recent Federal Regulation Documents

This document proposes adopting a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model AS350B, BA, B1, B2, B3, C, D, and D1 helicopters that have a Geneva Aviation, Inc. (Geneva) P132 console (console) installed. This proposal would require installing right and left side Geneva cyclic control sticks and modifying the cyclic grips and the co-pilot cyclic stand (receptacle). This proposal is prompted by reports that pilots had restricted cyclic stick travel when using Eurocopter factory-installed cyclic sticks in a helicopter that has been modified in accordance with a certain Supplemental Type Certificate (STC) for the installation of a Geneva P132 console. The actions specified by this proposed AD are intended to prevent restricting full lateral movement of the cyclic control during high lateral center of gravity (CG) load operations in high cross winds and during slope takeoffs or landings, and subsequent loss of control of the helicopter.

This notice proposes to establish Class D and Class E4 airspace and amend Class E5 airspace at Leesburg, FL. A Federal contract lower with a weather reporting system is being constructed at the Leesburg Regional Airport. Therefore, the airport will meet the criteria for establishment of Class D and Class E4 airspace. Class D surface area airspace and Class E4 airspace designated as an extension to Class D airspace is required when the control tower is open to contain existing Class D airspace is required when the control tower is open to contain existing Standard Instrument Approach Procedures (SIAPs) and other Instrument Flight Rules (IFR) operations at the airport. This action would establish Class D airspace extending upward from the surface to but not including 1,600 feet MSL within a 4.1-mile radius of the Leesburg Regional Airport and a Class E4 airspace extension that is 4.8 miles wide and extends 7 miles southeast of the airport. A regional evaluation has determined the existing Class E5 airspace area should be amended to contain the Nondirectional Radio Beacon (NDB) Runway (RWY) 31 SIAP. As a result, controlled airspace extending upward from 700 feet Above Ground Level (AGL) needed to contain the SIAP will decrease from a 7-mile radius of the airport to a 6.6-mile radius of the airport and provide for the procedure turn area. Additionally, a technical amendment is required as a result of a name change from the Leesburg Municipal Airport to the Leesburg Regional Airport, which was effective August 25, 1997.

These special conditions are issued for Cessna Aircraft Company Model 501 and 551 series airplanes modified by Elliott Aviation Technical Product Development, Inc. These airplanes will have novel and unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The modification incorporates the installation of Universal Aviation Electronic Flight Display Systems. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for the protection of these systems from the effects of high- intensity-radiated fields (HIRF). 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.

These special conditions are issued for Raytheon Aircraft Company Model BAe.125 Series 800A airplanes modified by Duncan Aviation Inc. These modified airplanes will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The modification incorporates the installation of the Honeywell Primus Epic CDS/R Display System. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for protecting these systems from the effects of high-intensity radiated fields (HIRF). These special conditions contain the additional safety standards the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
