Public Notice for Waiver of Aeronautical Land-Use Assurance; Oakland County International Airport; Pontiac, MI
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 sale of the airport property. The proposal consists of 14 parcels of land totaling approximately 3.981 acres. Current use and present condition is vacant grassland. The land is zoned residential. The land was acquired under FAA Project Nos. 3-26-0079-0694, C-26-0079-0795, B-26-0079-1397, 3-26-SBGP-1098, and 3- 26-SBGP-1799, and 3-26-SBGP-1999. There are no impacts to the airport by allowing the airport to dispose of the property. This land is to be sold for proposed use to accommodate the relocation of Williams Lake Road, which will provide a fully compliant runway safety area for Runway 9R. Approval does not constitute a commitment by the FAA to financially assist in the disposal of the subject airport property nor a determination of eligibility for grant-in-aid funding from the FAA. The disposition of proceeds from the disposal of the airport property will be in accordance 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.

Revocation of VOR Federal Airway V-623
This action revokes VOR Federal Airway V-623 that extends from the Sparta, NJ, Very High Frequency Omnidirectional Range/Tactical Air Navigation (VORTAC) to the Carmel, NY, Very High Frequency Omnidirectional Range/Distance Measuring Equipment (VOR/DME). The FAA is taking this action due to unsatisfactory navigation signal coverage.
Airworthiness Directives; Airbus Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes); and Model A310 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus models, as specified above. This proposed AD would require modifying the aft pressure bulkhead for improved corrosion protection and drainage, and related concurrent actions. This proposed AD is prompted by severe corrosion found in the lower rim area of the aft pressure bulkhead during routine maintenance of an airplane. We are proposing this AD to prevent corrosion on the inner rim angle and cleat profile splice of the aft pressure bulkhead, which could result in the loss of airplane structural integrity.
Airworthiness Directives; Airbus Model A321 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A321 series airplanes. This proposed AD would require repetitive measurements for correct control rod gap of the hold-open mechanism of all emergency doors, and corrective actions if necessary. This proposed AD would also require replacing the control rods with new, improved control rods, which would terminate the repetitive measurements. This proposed AD is prompted by a report that an operator found it impossible to lock emergency doors 2 and 3 in the open position. We are proposing this AD to prevent failure of the emergency doors to lock in the open position, which could interfere with passenger evacuation during an emergency.
Airworthiness Directives; Saab Model SAAB 2000 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Saab Model SAAB 2000 series airplanes. This proposed AD would require inspection for cracking of the fastener holes in the front and rear spar, modification of the fastener holes of the front and rear spars and the rear spar web, and related investigative/ corrective actions if necessary. This proposed AD is prompted by a report of cracking of certain fastener holes in the lower spar cap of the rear spar and in the lower skin at the front spar. We are proposing this AD to prevent cracking of the front and rear spar, which could result in fuel leakage and consequent reduced structural integrity of the wing structure.
Airworthiness Directives; Short Brothers Model SD3 Series Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Short Brothers Model SD3-30 and SD3- 60 series airplanes equipped with certain fire extinguishers. The existing AD currently requires replacement of the covers for fire extinguisher adapter assemblies that are installed on certain bulkheads with new covers that swivel to lock the extinguishers in place; and replacement of nozzles and triggers on these fire extinguishers with better fitting nozzles and stronger triggers. The existing AD also currently requires the installation of new fire extinguisher point placards and a revision of the Airplane Flight Manual (AFM) to instruct the flightcrew in the use of the new covers for these adapter assemblies. This proposed AD would also require modification of the fire extinguishing point adapter assembly of the forward and aft baggage bays as applicable. This proposed AD also would add airplanes to the applicability. For these new airplanes, this proposed AD would require a revision to the AFM for instructions on using the new fire extinguisher adapter. This proposed AD is prompted by reports of individuals experiencing fire extinguishant blowback when the extinguishant discharges through the fire extinguishing point adapters. We are proposing this AD to prevent fire extinguishant blowback, which could result in injury to a person using the fire extinguisher in the event of a fire.
Airworthiness Directives; Boeing Model 737-100, -200, -200C, -300, -400, and -500 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD would require operators to examine the airplane's maintenance records to determine if the main landing gear (MLG) has been overhauled and if Titanine JC5A (also known as Desoto 823E508) corrosion-inhibiting compound (``C.I.C.'') was used during the overhaul. For airplanes for which the maintenance records indicate that further action is necessary, or for airplanes on which C.I.C. JC5A may have been used during manufacture, this proposed AD would require a one-time detailed inspection for discrepancies of certain components of the MLG, and corrective action if necessary. This proposed AD is prompted by twelve reports of severe corrosion on one or more of three components of the MLG. We are proposing this AD to prevent collapse of the MLG, or damage to hydraulic tubing or the aileron control cables, which could result in possible departure of the airplane from the runway and loss of control of the airplane.
Airworthiness Directives; Boeing Model 767 Series Airplanes Powered by General Electric or Pratt & Whitney Engines
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Boeing Model 767 series airplanes. The existing AD currently requires repetitive inspections to detect discrepancies of the eight aft-most fastener holes in the horizontal tangs of the midspar fitting of the strut, and corrective actions if necessary. That AD also provides an optional terminating action for the repetitive inspections. This proposed AD would add repetitive inspections for cracks of the closeout angle that covers the two aft-most fasteners in the lower tang of the midspar fitting, and related investigative and corrective actions if necessary. This proposed AD also would reduce the inspection interval of the upper tang of the outboard midspar fitting; and would provide an optional terminating action for the repetitive inspections. This proposed AD is prompted by a report of a crack in a closeout angle that covers the two aft-most fasteners in the lower tang of the midspar fitting; and the discovery of a crack in the lower tang of the midspar fitting under the cracked closeout angle. We are proposing this AD to prevent fatigue cracking in the primary strut structure and reduced structural integrity of the strut, which could result in separation of the strut and engine.
Airworthiness Directives; Boeing Model 777-200 and -300 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 777-200 and -300 series airplanes. This proposed AD would require repetitive detailed inspections of the forward lugs of the power control unit (PCU), yoke assembly, and forward attachment hardware of the left inboard, left outboard, right inboard, and right outboard flaperon PCUs; and other specified/ corrective actions if necessary. For certain airplanes, the proposed AD also would require other related concurrent actions. This proposed AD is prompted by reports indicating that operators have found worn, fretted, and fractured bolts that attach the yoke assembly to the flaperon PCU. We are proposing this AD to prevent damage and eventual fracture of the yoke assembly, pin assembly, and attachment bolts that connect the inboard and outboard PCUs to a flaperon, which could lead to the flaperon becoming unrestrained and consequently departing from the airplane. Loss of a flaperon could result in asymmetric lift and reduced roll control of an airplane. A departing flaperon could also cause damage to the horizontal and vertical stabilizers, which could result in loss of control of the airplane if damage is significant.
Airworthiness Directives; Airbus Model A300 B2 and B4 Series Airplanes
This document corrects a typographical error that appeared in airworthiness directive (AD) 2005-03-14, which was published in the Federal Register on February 14, 2005 (70 FR 7384). The typographical error resulted in an incorrect reference to an AD number. This AD is applicable to certain Airbus Model A300 B2 and B4 series airplanes. This AD supersedes an existing AD that currently requires determining the part and amendment number of the variable lever arm (VLA) of the rudder control system to verify that the parts were installed using the correct standard, and corrective actions if necessary. For certain VLAs, this new AD requires repetitive inspections of the VLA and corrective action if necessary. This new AD also provides a terminating action for the repetitive inspections. Furthermore, this new AD reduces the applicability of affected airplanes.
Airworthiness Directives; McDonnell Douglas Model MD-11 and -11F Airplanes; Model DC-10-10 and DC-10-10F Airplanes; Model DC-10-15 Airplanes; Model DC-10-30 and DC-10-30F (KC-10A and KDC-10) Airplanes; Model DC-10-40 and DC-10-40F Airplanes; and Model MD-10-10F and MD-10-30F Airplanes
The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD) for certain McDonnell Douglas transport category airplanes. The proposed AD would have required replacement with new, improved parts of the inboard flap, outboard hinge, forward attach bracket, and lower attach bolt assemblies. The proposed AD also would have required an inspection for certain parts, and related investigative and corrective actions if necessary. Since the proposed AD was issued, we have confirmed data indicating that an existing AD adequately addresses the unsafe condition. Accordingly, the proposed AD is withdrawn.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all EMBRAER Model ERJ 170 series airplanes. This proposed AD would require inspecting the hydraulic pressure tubes at the outlet of the engine-driven hydraulic pumps to determine the part and serial numbers; and replacing hydraulic pressure tubes having certain serial numbers with new hydraulic pressure tubes. This proposed AD is prompted by failure of a hydraulic system due to leakage of hydraulic fluid from a crack in the pipe coming from the pressure side of the engine driven pump. We are proposing this AD to prevent cracking of the hydraulic pressure pipes, which could result in failure of hydraulic system 1 or 2 or both, and consequent reduced controllability of the airplane.
