Quiet Aircraft Technology Incentive for Commercial Air Tour Operators in Grand Canyon National Park
The Moving Ahead for Progress in the 21st Century Act (MAP-21) directs the Administrator of the Federal Aviation Administration (FAA) and the Secretary of the Interior to provide incentives for commercial air tour operators in Grand Canyon National Park that convert to quiet aircraft technology. The FAA holds a limited number of flight allocations that are authorized under 14 CFR part 93, Subpart U, ``Special Flight Rules in the Vicinity of Grand Canyon National Park.'' The FAA, in consultation with the National Park Service (NPS), intends to provide these allocations to commercial air tour operators that currently hold allocations in proportion to the number of quiet aircraft technology operations that are flown by respective operators in the first six months of calendar year 2014. This is a one-time release of FAA-held allocations that will be available to operators for quiet aircraft technology flights during the 2014 air tour season and beyond. The FAA and NPS are continuing to make progress on additional quiet aircraft technology incentives for commercial air tour operators in Grand Canyon National Park.
Airworthiness Directives; Fokker Services B.V. Airplanes
We propose to adopt a new airworthiness directive (AD) for all Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes. This proposed AD was prompted by reports that the bracket of the rod in the carbon fiber reinforced plastic (CFRP) main landing gear (MLG) outboard door had detached. In addition, we received reports of broken recessed heads on titanium attachment bolts of the operating rod brackets on the modified CFRP MLG outboard doors. This proposed AD would require a detailed inspection of the CFRP MLG outboard door for play or cracks in the recessed countersunk heads of the operating rod bracket attachment bolts; replacement of the bolt if necessary; and, for certain airplanes, modification of the CFRP MLG outboard doors and attachment to the MLG. We are proposing this AD to detect and correct the affected MLG from moving to the down and locked position, which could result in MLG collapse during landing or roll-out, and consequent damage to the airplane and injury to passengers.
Airworthiness Directives; Embraer S.A. Airplanes
We propose to supersede Airworthiness Directive (AD) 2012-23- 09, for all Embraer S.A. Model ERJ 190-100 STD, -100 LR, and -100 IGW airplanes; and Model ERJ 190-200 STD, -200 LR, and -200 IGW airplanes. AD 2012-23-09 currently requires revising the maintenance program to incorporate modifications in airworthiness limitations specified in Embraer S.A. ERJ 190 195 Maintenance Review Board Report (MRBR). Since we issued AD 2012-23-09, we have determined that more restrictive maintenance requirements and airworthiness limitations are necessary. This proposed AD would require revising the maintenance or inspection program to incorporate modifications in the airworthiness limitations specified in Embraer S.A. ERJ 190 195 MRBR to include new inspection tasks and their respective thresholds and intervals. We are proposing this AD to detect and correct fatigue cracking of structural components, which could result in reduced structural integrity of the airplane.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A310 series airplanes. This proposed AD was prompted by a report of an electrical arc and a hydraulic haze in the wheel bay of the left-hand main landing gear (MLG), possibly resulting from chafing between a hydraulic high pressure hose and electrical wiring of the green electrical motor pump (EMP). This proposed AD would require modification of the electrical routing and replacement of the union elbows. We are proposing this AD to prevent chafing of hydraulic pressure hoses and electrical wiring of the green EMPs, which, in combination with a system failure, could cause an uncontrolled and undetected fire in the MLG bay.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A330-200 Freighter, A330-200, A330-300, A340-200, and A340-300 series airplanes. This proposed AD was prompted by the results of endurance qualification tests on the trimmable horizontal stabilizer actuator (THSA), which revealed a partial loss of the no-back brake (NBB) efficiency in specific load conditions. This proposed AD would require inspecting certain THSAs to determine the number of total flight cycles the THSA has accumulated, and replacing the THSA if necessary. We are proposing this AD to detect and correct premature wear of the carbon friction disks on the NBB of the THSA, which could lead to reduced braking efficiency in certain load conditions and, in conjunction with the inability of the power gear train to keep the ball screw in its last commanded position, could result in uncommanded movements of the THS and loss of control of the airplane.
Minimum Altitudes for Use of Autopilots
This rulemaking amends and harmonizes minimum altitudes for use of autopilots for transport category airplanes; it also enables the operational use of advanced autopilot and navigation systems by incorporating the capabilities of current and future autopilots, flight guidance systems, and Global Navigation Satellite System (GNSS) guidance systems while protecting the continued use of legacy systems at current autopilot minimum use altitudes. Additionally, this final rule implements a performance-based approach, using the certified capabilities of autopilot systems as established by the Airplane Flight Manual (AFM) or as approved by the Administrator.
Use of Additional Portable Oxygen Concentrators on Board Aircraft
This action amends the FAA's rules for permitting use of portable oxygen concentrator (POC) devices on board aircraft, provided certain conditions in the SFAR are met. This action is necessary to allow all POC devices deemed acceptable by the FAA for use in air commerce to be available to the traveling public in need of oxygen therapy. Passengers will be able to carry these devices on board the aircraft and use them with the approval of the aircraft operator.
Establishment of Class E Airspace, Amendment of Class D and Class E Airspace, and Revocation of Class E Airspace; Salinas, CA
This action establishes Class E airspace and modifies Class D airspace and Class E airspace at Salinas, CA, to accommodate aircraft departing and arriving under Instrument Flight Rules (IFR) at Salinas Municipal Airport. This action also removes Class E airspace designated as surface area. Adjustments to the geographic coordinates of the airport also are made in the respective Class D airspace and Class E airspace areas. This action, initiated by the biennial review of the Salinas airspace area, enhances the safety and management of aircraft operations at the airport.
