Airworthiness Directives; Sikorsky Aircraft Corporation Model S-61L, N, R, and NM Helicopters
This amendment adopts a new airworthiness directive (AD) for the specified Sikorsky Aircraft Corporation (Sikorsky) model helicopters that requires, within a specified time, creating a component history card or equivalent record. The AD also requires recording the hours time-in-service (TIS) and the external lift cycles (lift cycles) for each main gearbox input left and right freewheel unit (IFWU) assembly. Also, the AD requires calculating a moving average of lift cycles per hour TIS at specified intervals on each IFWU assembly. The moving average is used to determine if an IFWU assembly is used in repetitive external lift (REL) or non-REL helicopter operations. If an IFWU assembly is used in REL operations, this AD requires a visual and dimensional inspection of the IFWU assembly at specified intervals. This AD also requires recording certain information and replacing each part that is beyond the wear limits or that exhibits visual surface distress with an airworthy part. In addition, this AD requires permanently marking the REL IFWU camshafts and gear housings with the letters ``REL'' on the surface of these parts. This amendment is prompted by an accident in which the left and right IFWU assembly on a helicopter slipped or disengaged resulting in both engines over speeding, engine shutdowns, and loss of engine power to the transmissions. The actions specified by this AD are intended to prevent slipping in the IFWU assembly, loss of engine power to the transmissions, and subsequent loss of control of the helicopter.
Special Conditions: Dassault Aviation Model Falcon 7X Airplane, Windshield Coating in Lieu of Wipers
This special condition is issued for the Dassault Aviation Model Falcon 7X airplane. This airplane will have a novel or unusual design feature associated with use of a hydrophobic windshield coating, rather than windshield wipers, as the means to maintain a clear portion of the windshield during precipitation conditions, as required by the airworthiness standards for transport category airplanes. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. This special condition contains the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Special Conditions: Gulfstream Aerospace Corporation Model G-1159A Airplanes; High-Intensity Radiated Fields (HIRF)
The FAA issues these special conditions for a Gulfstream Aerospace Corporation Model G-1159A airplane modified by AeroMech Incorporated. This modified airplane 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 Innovative Solutions and Support integrated air data display units (ADDU). These systems perform critical functions. 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.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 and ERJ 190 Airplanes
This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2006-20-14 that was sent previously to all known U.S. owners and operators of certain EMBRAER Model ERJ 170 and ERJ 190 airplanes by individual notices. This AD requires modification of certain flight deck door electronic equipment. This AD is prompted by a report indicating that this equipment is defective. We are issuing this AD to prevent failure of this equipment, which could jeopardize flight safety.
Airworthiness Directives; McDonnell Douglas Model MD-11 and -11F Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain McDonnell Douglas Model MD-11 and -11F airplanes. That AD currently requires an initial general visual inspection of the power feeder cables of the integrated drive generator (IDG) and the fuel feed lines of engine pylons No. 1 and No. 3 on the wings for proper clearance and damage; corrective actions if necessary; and repetitive general visual inspections and a terminating action for the repetitive inspections. This new AD requires the existing actions, and for certain airplanes, this AD requires installation of new clamps on the power feeder cables of the IDG of engine pylons No. 1 and No. 3. This AD results from reports of IDG power feeder cables riding against structure and fuel lines in the No. 1 and No. 3 pylons. We are issuing this AD to prevent potential chafing of the power feeder cables of the IDG in engine pylons No. 1 and No. 3 on the wings, and consequent arcing on the fuel lines in the engine pylons and possible fuel fire.
Airworthiness Directives; Turbomeca Artouste III B and III B1 Turboshaft Engines
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:
Notice of Passenger Facility Charge (PFC) Approvals and Disapprovals
The FAA publishes a monthly notice, as appropriate, of PFC approvals and disapprovals under the provisions of the Aviation Safety and Capacity Expansion Act of 1990 (Title IX of the Omnibus Budget Reconciliation Act of 1990) (Pub. L. 101-508) and Part 158 of the Federal Aviation Regulations (14 CFR part 158). This notice is published pursuant to paragraph d of Sec. 158.29.
Notice of Passenger Facility Charge (PFC) Approvals and Disapprovals
The FAA publishes a monthly notice, as appropriate, of PFC approvals and disapprovals under the provisions of the Aviation Safety and Capacity Expansion Act of 1990 (Title IX of the Omnibus Budget Reconciliation Act of 1990) (Pub. L. 101-508) and Part 158 of the Federal Aviation Regulations (14 CFR Part 158). This notice is published pursuant to paragraph d of Sec. 158.29.
Notice of Opportunity for Public Comment on Surplus Property Release at the Myrtle Beach International Airport, Myrtle Beach, SC
Under the provisions of Title 49, U.S.C. Section 47153(c), notice is being given that the FAA is considering a request from Horry County to waive the requirement that approximately 33acres of surplus property, located at the Myrtle Beach International Airport, be used for aeronautical purposes.
