Airworthiness Directives; MD Helicopters, Inc. (MDHI) Helicopters
We propose to adopt a new airworthiness directive (AD) for MDHI Model 500N, 600N, and MD900 helicopters to require determining the cure date for each NOTAR fan blade tension-torsion strap (T-T strap), establishing a calendar-time retirement life for certain T-T straps, reducing the retirement life of certain T-T straps, marking each T-T strap with the expiration date, creating a component record card for each T-T strap, and revising the airworthiness limitations section of the maintenance manual to reflect the changes to the retirement life. This proposal is prompted by a report from the T-T strap manufacturer that, over a period of time, moisture may reduce the strength of a T-T strap. The proposed actions are intended to prevent failure of a T-T strap, loss of directional control and subsequent loss of control of the helicopter.

The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on May 9, 2012, vol. 77, no. 90, page 27271-27272. The commercial air tour operational data provided to the FAA and NPS will be used by the agencies as background information useful in the development of air tour management plans and voluntary agreements for purposes of meeting the mandate of the National Parks Air Tour Management Act (NPATMA) of 2000.
Airworthiness Directives; Bombardier, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This proposed AD was prompted by reports that airplanes with a Class C cargo (baggage) compartment have liners that do not meet flammability requirements. This proposed AD would require replacing the existing cargo compartment liners with liners that comply. We are proposing this AD to prevent inadequate fire protection in the cargo compartment and consequent uncontrolled fire.
Airworthiness Directives; Honeywell International, Inc. Global Navigation Satellite Sensor Units
We are adopting a new airworthiness directive (AD) for certain aircraft equipped with Honeywell International, Inc. Model KGS200 Mercury\2\ wide area augmentation system (WAAS) global navigation satellite sensor units (GNSSU). This AD requires you cease all localizer performance (LP), localizer performance with vertical guidance (LPV), and satellite based augmentation system (SBAS) lateral navigation/vertical navigation (LNAV/VNAV) approaches until a software problem is corrected. This AD was prompted by a report and follow-up investigation of a software problem that occurred during flight test trials of SBAS-capable aircraft using a similar Honeywell global positioning system (GPS) sensor and the same software as the Model KGS200 Mercury\2\ GNSSU. A software problem occurred that could result in misleading information during LP, LPV, or SBAS LNAV/VNAV approaches. We are issuing this AD to correct the unsafe condition on these products.
Airworthiness Directives; Piper Aircraft, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for all Piper Aircraft, Inc. (type certificate previously held by The New Piper Aircraft Inc.) Models PA-18 and PA-19 airplanes. This proposed AD was prompted by incidents of inadvertent magneto switch shut off in flight. This proposed AD would require moving all magneto switches that are now or are at any time located on the left cabin panel, adjacent to the front seat, to the instrument panel. We are proposing this AD to correct the unsafe condition on these products.
Airworthiness Directives; Piaggio Aero Industries S.p.A.
We propose to rescind Airworthiness Directive (AD) 200-07-11 for all Piaggio Aero Industries S.p.A Model P-180 airplanes. That AD was prompted by mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Italy. We issued that AD to prevent the brake hydraulic fluid from leaking because of the brake assembly rods contacting the brake valve tubing, which could result in the inability to adequately stop the airplane during ground operations. Since we issued that AD, we have determined this is no longer an unsafe condition and that regularly scheduled annual inspections address this subject.
Airworthiness Directives; Bell Helicopter Textron Canada Helicopters
We are adopting an airworthiness directive (AD) superseding an existing airworthiness directive for Bell Helicopter Textron Canada (Bell) Model 407 and 427 helicopters. The existing AD requires inspecting certain hydraulic servo actuators (servo) to determine whether the shaft turns independently of the nut or the clevis assembly, and additional actions based upon the inspection's outcome. The AD also requires reidentifying the servo. Since we issued that AD, Bell has learned that additional servos may need repair or removal. This AD expands the scope of the current AD to include inspections for all servos, and requires that servos meeting inspection requirements be marked with the letter ``V'' after the part number on the data plate. The actions are intended to detect any loose or misaligned parts in the servo that could lead to failure of the servo and subsequent loss of helicopter control.
Revocation of Class E Airspace; Lloydsville, PA, and Amendment of Class D and E Airspace; Latrobe, PA
This action removes Class E airspace listed at Lloydsville, PA, for Latrobe Hospital Heliport (old name), and incorporates Excela Health Latrobe Hospital Heliport (new name) onto Class E airspace at Latrobe, PA. Also, this action amends Class D and E airspace at Latrobe, PA, as new Standard Instrument Approach Procedures have been developed at Arnold Palmer Regional Airport. The geographic coordinates for both the heliport and the airport are updated. This action enhances the safety and airspace management of Instrument Flight Rules (IFR) operations in the Latrobe, PA, area. This action also recognizes the airport name change to Arnold Palmer Regional Airport.
Amendment of Jet Routes and VOR Federal Airways; Northeastern United States
This action amends the descriptions of 14 Jet Routes and 9 VOR Federal airways in the northeastern United States to reflect route changes made in Canadian airspace as part of Canada's Windsor-Toronto- Montreal airway project.
Amendment of Air Traffic Service (ATS) Routes in the Vicinity of Vero Beach, FL
This action amends the legal descriptions of Jet Routes J-45 and J-79, and VHF omnidirectional range (VOR) Federal airways V-3, V-51, V-159, V-225, V-295 and V-537, in the vicinity of Vero Beach, FL. The FAA is taking this action because the name of the Vero Beach, FL, VOR Tactical Air Navigation (VORTAC) facility, which is included in the descriptions of the above routes, is being changed to the Treasure VORTAC.
Establishment of Class E Airspace; West Memphis, AR
This action establishes Class E airspace at West Memphis, AR. Separation of existing Class E airspace surrounding West Memphis Municipal Airport from the Class E airspace of Memphis International Airport, Memphis, TN, has made this action necessary to enhance the safety and management of Instrument Flight Rules (IFR) operations at the airport.
Amendment of Class E Airspace; Grinnell, IA
This action amends Class E airspace at Grinnell Regional Airport, Grinnell, IA, by removing reference to the Grinnell NDB from the legal description, and amends the geographic coordinates of the airport. The Grinnell NDB has been decommissioned and is not needed as part of the airspace description. This action does not change the boundaries or operating requirements of the airspace.
Airworthiness Directives; Pratt & Whitney Turbofan Engines
We are superseding an existing airworthiness directive (AD) for all Pratt & Whitney Division PW4074 and PW4077 turbofan engines. That AD currently requires removing the 15th stage high-pressure compressor (HPC) disk within 12,000 cycles since new (CSN) or using a drawdown removal plan for disks that exceed 12,000 CSN. This new AD requires the same actions and clarifies that 15th stage HPC disks that have accumulated more than 9,865 CSN require a borescope inspection (BSI) or eddy current inspection (ECI) of the disk outer rim front rail for cracks prior to accumulating 12,000 CSN. This AD was prompted by a request from an operator that we clarify our inspection schedule for 15th stage HPC disks that have accumulated more than 9,865, but less than 12,000 CSN, on the effective date of the AD. We are issuing this AD to prevent cracks from propagating into the disk bolt holes, which could result in a failure of the 15th stage HPC disk, uncontained engine failure, and damage to the airplane.
