Airworthiness Directives; Agusta S.p.A. Helicopters
We propose to adopt a new airworthiness directive (AD) for certain Agusta S.p.A. (Agusta) Model AW139 helicopters. This proposed AD is prompted by the discovery of improper installation of solder splices on the co-pilot audio system causing intermittent noise through the audio system during flight. The proposed actions are intended to prevent degradation and complete loss of communications between the pilot and co-pilot during flight, impairing the co-pilot's capability to react immediately to operational difficulties, which could lead to subsequent loss of control of the helicopter.
Living History Flight Experience (LHFE)-Exemptions for Passenger Carrying Operations Conducted for Compensation and Hire in Other Than Standard Category Aircraft
The FAA is announcing public meetings to gather additional technical input on the subject of exemptions relating to the LHFE. Input gathered will aid in developing future FAA guidance for evaluating LHFE petitions for exemption. Prior to the public meetings, the FAA is seeking public comment on the guidance.
Sec. 221 Public Private Partnerships Public Meeting
The FAA is conducting a public meeting on May 30 to seek initial input from interested stakeholders about program design and implementation of an equipage incentives program for commercial aircraft and general aviation to equip their aircraft with Next Generation Air Transportation (NextGen) capabilities, pursuant to the FAA's authority in the FAA Modernization and Reform Act of 2012 (sec. 221). The statute requires that such a program be based on public- private partnership (PPP) principles and maximize the use of private sector capital. The purpose of this meeting is to serve as an information sharing session. The FAA is interested in engaging stakeholders and potential public-private partners in the process of developing an effective public-private partnership equipage incentive program. This notice is for the initial meeting. A subsequent meeting will be planned within 90 days of the May 30 meeting after FAA has assessed stakeholder comments and feedback and further solidified its policy on how to implement a PPP equipage incentives program.
Airport Improvement Program (AIP) Use of Mineral Revenue at Certain Airports
On February 14, 2012, the FAA Modernization and Reform Act of 2012 (FMRA) was signed into law (Pub. L. 112-95). Section 813 permits the Administrator of the Federal Aviation Administration (FAA) to declare certain revenue derived from or generated by mineral extraction, production, lease, or other means at a general aviation airport to be revenue greater than the amount needed to carry out the five-year projected maintenance needs of the airport in order to comply with the applicable design and safety standards of the Administration. Although the FMRA directed the FAA to promulgate regulations to carry out Section 813 not later than 90 days after the date of enactment, the authorizing committees agreed to support the FAA's request to issue guidance in lieu of a formal rulemaking due to the time limits imposed by the statute. This notice contains the FAA's proposed guidance developed to carry out Section 813 and offers the public an opportunity to comment.
Airworthiness Directives; Agusta S.p.A. Helicopters
We propose to adopt a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model A109E and Model A109S helicopters with certain lower semichannel assemblies installed. This proposed AD results from reported cases of damage to the main drive shaft caused by improperly secured metallic spacers on some A109 model helicopters. This proposed AD would require a one-time inspection of the lower semichannel assemblies to determine if metallic spacers are installed. If the metallic spacers are installed, this proposed AD would require an inspection for the correct installation of the metallic spacers on the semichannels and for the correct seating of the gaskets. If the metallic spacers are not installed with rivets, the lower semichannel assemblies would be required to be modified, and the main drive shaft would be inspected for damage. The actions specified by this proposed AD are intended to detect missing spacer rivets, which could allow the metallic spacers to rotate and lead to damage and failure of the main drive shaft, and subsequent loss of helicopter control.
Airworthiness Directives; Bell Helicopter Textron Helicopters
We propose to adopt a new airworthiness directive (AD) for Bell Helicopter Textron (BHT) Model 412, 412EP, and 412CF helicopters. This proposed AD is prompted by a reported failure of a collective lever. These proposed actions are intended to detect a crack in the collective lever, which could lead to failure of the collective lever and subsequent loss of control of the helicopter.
Airworthiness Directives; Eurocopter Deutschland Helicopters
We propose to adopt a new airworthiness directive (AD) for all Eurocopter Deutschland GmbH Model MBB-BK117 C-2 helicopters with certain Generator Control Units (GCU) installed. This proposed AD is prompted by reports of internal short circuits in certain GCUs. The proposed actions are intended to replace any affected GCUs to prevent a short circuit, which could result in a loss of electrical generating power, loss of systems required for continued safe flight and landing, and subsequent loss of control of the helicopter.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A300 B4-600 and A300 B4-600R, Model A300, and Model A310 series airplanes. This proposed AD was prompted by reports of fatigue cracking in the crossbeams at the junction of the actuator beam of the lower deck cargo door. This proposed AD would require repetitive inspections of the crossbeams of certain fuselage frames, and repair if necessary. We are proposing this AD to detect and correct cracking of the crossbeams at the junction of the actuator beam of the lower deck cargo door, which could result in failure to withstand ultimate load conditions, and consequent reduced structural integrity of the airplane.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are superseding an existing airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701 & 702), CL-600-2D15 (Regional Jet Series 705), and CL-600-2D24 (Regional Jet Series 900) airplanes. That AD currently requires a one- time inspection of the main landing gear (MLG) shock strut assemblies for part and serial numbers; for certain MLG shock strut assemblies, a one-time inspection of the torque link apex joint, and corrective actions if necessary; and, for certain MLG shock strut assemblies, replacement or rework of the apex nut. This new AD continues to require the actions in the existing AD, and adds the previously omitted part and serial numbers. This AD was prompted by reports of loose or detached main landing gear (MLG) torque link apex pin locking plate and the locking plate retainer bolt in the torque link apex joint. We are issuing this AD to detect and correct improper assembly and damage of the MLG torque link apex joint, which could cause heavy vibration during landing, consequent damage to MLG components, and subsequent collapse of the MLG.
Amendment of Class E Airspace; Rock Springs, WY
This action amends Class E airspace at Rock Springs-Sweetwater County Airport, Rock Springs, WY. Decommissioning of the Rock Springs Tactical Air Navigation System (TACAN) has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the airport. This action also adjusts the geographic coordinates of the airport.
