Airworthiness Directives; Hawker Beechcraft Corporation Model BH.125 Series 600A Airplanes and Model HS.125 Series 700A Airplanes Modified in Accordance With Supplemental Type Certificate (STC) SA2271SW
We propose to adopt a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Model BH.125 series 600A airplanes and Model HS.125 series 700A airplanes. This proposed AD would require inspecting the wiring diagrams containing the cockpit blowers and comparing with the current airplane configuration, and reworking the wiring if necessary. This proposed AD results from a report indicating that a blower motor of the cockpit ventilation and avionics cooling system seized up and gave off smoke. We are proposing this AD to prevent smoke and fumes in the cockpit in the event that a blower motor seizes and overheats due to excessive current draw.
Airworthiness Directives; Boeing Model 747 Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Boeing Model 747 airplanes. This proposed AD would require repetitive external surface high frequency eddy current inspections to detect cracks in the radius detail of the upper lobe doubler on both sides of the airplane, and applicable corrective action. This proposed AD results from reports of cracks in the radius detail of the upper lobe doublers. We are proposing this AD to detect and correct cracks in the upper lobe doublers. Such cracks could result in significant degradation of the fuselage structure and reduce its ability to carry flight loads from the vertical stabilizer, which could adversely affect the controllability of the airplane.
Airworthiness Directives; ATR Model ATR42-200, ATR42-300, ATR42-320, ATR42-500, ATR72-101, ATR72-201, ATR72-102, ATR72-202, ATR72-211, ATR72-212, and ATR72-212A Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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:
Airworthiness Directives; McDonnell Douglas Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, DC-10-40F, MD-10-10F, and MD-10-30F Airplanes
The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to certain McDonnell Douglas Model DC-10- 10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC- 10-40, and DC-10-40F airplanes. The original NPRM would have revised an existing AD that currently requires installing or replacing with improved parts, as applicable, the bonding straps between the metallic frame of the fillet and the wing leading edge ribs, on both the left and right sides of the airplane. The original NPRM proposed to revise the applicability to clarify the identity of the affected airplanes. The original NPRM resulted from fuel system reviews conducted by the manufacturer. This new action proposes to revise the applicability to add and remove certain airplanes, and to add a requirement to reposition or replace two bonding straps for certain airplanes. This new action also proposes to supersede, rather than revise, the existing AD. We are proposing this supplemental NPRM to reduce the potential of ignition sources inside fuel tanks in the event of a severe lightning strike, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
Airworthiness Directives; Bell Helicopter Textron Canada Model 206L, 206L-1, and 206L-3 Helicopters
This document proposes to revise an existing airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) Model 206L, 206L-1, and 206L-3 helicopters with certain part-numbered tailbooms. That AD currently requires a visual inspection of the tailboom skin in the areas around the nutplates and in the areas of the tailboom drive shaft cover retention clips for cracks and corrosion using a 10-power or higher magnifying glass until the tailboom is replaced with an airworthy tailboom. This action would require the same actions as the existing AD but would allow a longer interval for the repetitive inspections if the tailboom is modified. Replacement with an airworthy tailboom other than a part-numbered tailboom affected by this proposal would constitute terminating action for the requirements of this AD. The existing AD was prompted by an accident and several reports of fatigue cracks in the tailboom skin in the areas around the nutplates for the tail rotor fairing and in the areas of the tail rotor drive shaft cover retention clips. These proposed actions are intended to prevent failure of the tailboom and subsequent loss of control of the helicopter.
Airworthiness Directives; Erickson Air-Crane Incorporated (Erickson) Model S-64F Helicopters
This document proposes adopting a new airworthiness directive (AD) for Erickson Model S-64F helicopters. The AD would require inspections for cracking or working rivets in each left and right splice fitting (transition fitting), the pylon bulkhead assembly canted (bulkhead assembly), the pylon steel strap (strap), and the attaching rotary rudder boom and pylon structure. This proposal is prompted by several reports of cracking in the transition fittings, the bulkhead assembly, and pylon. The actions specified by the proposed AD are intended to detect cracking in the rotary rudder boom or pylon due to fatigue, and to prevent failure from static overload and subsequent loss of control of the helicopter.
Establishment of Class D and Class E Airspace; Grayling, MI
This action establishes Class D airspace and Class E airspace at Grayling Army Airfield, Grayling, MI. Establishment of an air traffic control tower at Grayling Army Airfield has made this action necessary for the safety of Instrument Flight Rule (IFR) operations at the airport. Class D airspace will revert to a Class E Surface Area during periods when the control tower is not operating. This action also corrects the required arrival extension to the Class D airspace and redesignates it as Class E4 airspace.
Amendment of Class E Airspace; Big Spring, TX
This action amends Class E airspace at Big Spring McMahon- Wrinkle Airport, Big Spring, TX. Changes to the VOR/DME RWY 17 Standard Instrument Approach Procedure (SIAP) have made this action necessary for the safety of Instrument Flight Rule (IFR) operations at the airport.
Public Notice for Waiver of Aeronautical Land-Use Assurance; James M. Cox Dayton International Airport, Dayton, OH
The Federal Aviation Administration (FAA) is considering a proposal to change a portion of the airport from aeronautical use to non-aeronautical use and to authorize the release of 382.9796 acres of airport property for future non-aeronautical development. The land consists of portions of 19 original airport acquired parcels. These parcels were acquired under grants 9-33-025-C511, 9-33-025-C813, 8-39- 0029-01, 8-39-0029-03, 3-39-0029-03, and 3-39-0029-13 or without federal participation. There are no impacts to the airport by allowing the City of Dayton to sell or lease the property. The land is not needed for aeronautical use. Approval does not constitute a commitment by the FAA to financially assist in the sale or lease of the subject airport property nor a determination of eligibility for grant-in-aid funding from the FAA. The disposition of proceeds from the sale or lease of the airport property will be in accordance with FAA's Policy and Procedures Concerning the Use of Airport Revenue, published in the Federal Register on February 16, 1999. In accordance with section 47107(h) of title 49, United States Code, this notice is required to be published in the Federal Register 30 days before modifying the land-use assurance that requires the property to be used for an aeronautical purpose.
Proposed Amendment of Class E Airspace; Corpus Christi, TX
This action proposes to amend Class E airspace for the Corpus Christi, TX, area. Controlled airspace is necessary to accommodate Area Navigation (RNAV) Standard Instrument Approach Procedures (SIAPs) at Mustang Beach Airport, Port Aransas, TX; and T.P. McCampbell Airport, Ingleside, TX. Also, Class E airspace around Aransas County Airport, Rockport, TX, and San Jose Island Airport, Rockport, TX, would be incorporated into the Corpus Christi, TX, area Class E airspace. The Rockport, TX, designation is being removed under a separate rulemaking. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) aircraft operations in and around the Corpus Christi, TX, airspace area.
Proposed Amendment of Class D and Class E Airspace; Corpus Christi Naval Air Station/Truax Field, TX
This action proposes to amend the geographic coordinates of the Class D and E Airspace areas for Corpus Christi Naval Air Station (NAS)/Truax Field, Corpus Christi, TX. The FAA's National Aeronautical Charting Office is requesting this action to enhance the safety and management of Instrument Flight Rules (IFR) aircraft operations at Corpus Christi NAS/Truax Field.
Airworthiness Directives; CFM International S.A. Model CFM56 Turbofan Engines
The FAA proposes to adopt a new airworthiness directive (AD) for CFM International S.A. CFM56-2, CFM56-3, CFM56-5A, CFM56-5B, CFM56- 5C, and CFM56-7B series turbofan engines with certain part number (P/N) and serial number (SN) high-pressure compressor (HPC) 4-9 spools installed. This proposed AD would require removing certain HPC 4-9 spools listed by P/N and SN in this proposed AD. This proposed AD results from reports of certain HPC 4-9 spools that Propulsion Technology LLC (PTLLC) improperly repaired and returned to service. We are proposing this AD to prevent cracking of the HPC 4-9 spool, which could result in possible uncontained failure of the spool and damage to the airplane.
Airworthiness Directives; General Electric Company CF6-80C2 and CF6-80E1 Series Turbofan Engines
The FAA proposes to adopt a new airworthiness directive (AD) for General Electric Company (GE) CF6-80C2 and CF6-80E1 series turbofan engines with high-pressure compressor rotor (HPCR) spool shaft stage 14 disks, part number (P/N) 1703M49G02, 1703M49G03, or 1509M71G10 installed. This proposed AD would require a one-time eddy current inspection (ECI) of the HPCR spool shaft stage 14 disk web for crack indications, and removing from service any parts with web cracks. This proposed AD results from reports of 12 HPCR spool shaft stage 14 disks with web cracks discovered to date. We are proposing this AD to prevent cracks from propagating to an uncontained failure of the disk and damage to the airplane.
Special Conditions: Boeing Model 767-300 and -300F Series Airplanes; Interaction of Systems and Structures
These special conditions are issued for the Boeing Model 767- 300 and -300F airplane as modified by Aviation Partners Boeing Supplemental Type Certificate (STC). The modified airplane has novel or unusual design features involving installation of blended winglets and a speedbrake wing-load-alleviation system. This system reduces loading on the wing. The applicable airworthiness regulations for the Boeing Model 767-300 and -300F do not contain adequate or appropriate safety standards for systems which alleviate loads on structures. 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 applicable airworthiness standards.
