Airworthiness Directives; Boeing Model 737-600, -700, -700C, -800 and -900 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 737-600, -700, -700C, -800 and -900 series airplanes. This proposed AD would require inspecting ground blocks GD261 and GD264 for corrosion, measuring the electrical bond resistance between the ground blocks and the airplane structure, separating the ground wires for the fuel boost pump circuit between ground blocks GD261 and GD264, and doing corrective actions if necessary. This proposed AD results from a report of random flashes of the six fuel pump low pressure lights and intermittent operation of the fuel boost pumps. We are proposing this AD to prevent the simultaneous malfunction of all six fuel boost pumps, which could cause the engines to operate on suction feed and potentially flame out.
Airworthiness Directives; Gulfstream Aerospace LP Model Galaxy Airplanes and Model Gulfstream 200 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; Airbus Model A321 Series Airplanes

Airworthiness Directives; McDonnell Douglas Model 717-200 Airplanes
The FAA is revising an earlier proposed airworthiness directive (AD) for all McDonnell Douglas Model 717-200 airplanes. The original NPRM would have required inspecting the power conversion distribution unit (PCDU) to determine its part number, and modifying certain PCDUs. The original NPRM was prompted by reports of failed PCDUs, the loss of an electrical bus, and the presence of a strong electrical burning odor in the flight deck and forward cabin. This action revises the original NPRM by reidentifying the part number reference for the proposed corrective action. We are proposing this supplemental NPRM to prevent the loss of an electrical bus due to PCDU failure, resulting in the loss of all flight displays for an unacceptable time period, and consequent emergency landing.
Airworthiness Directives; Airbus Model A340-211, -212, -311, and -312 Airplanes
The FAA is superseding an existing airworthiness directive (AD) that applies to certain Airbus Model A340-211, -212, -311, and - 312 airplanes. The existing AD currently requires an initial rotating probe inspection and initial and repetitive ultrasonic inspections for discrepancies of the first fastener hole of the horizontal flange of the keel beam on previously modified airplanes, installation of new fasteners, and corrective action if necessary. This AD retains the actions required by the existing AD and adds new rotating probe inspections and a terminating action for the repetitive inspections of the existing AD. This AD results from a report that certain inspections, done before accomplishing the modification of the lower keel beam fitting and forward lower shell connection, revealed cracking that was outside the modification limits specified in the service bulletin; the cracking was repaired by installing a titanium doubler. We are issuing this AD to prevent discrepancies of the fastener holes of the horizontal flange of the keel beam, which could result in reduced structural integrity of the fuselage.
Airworthiness Directives; General Electric Company (GE) CF6-80C2B Series Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for GE CF6-80C2B series turbofan engines with electronic control units (ECUs), installed on Boeing 747 and 767 series airplanes. This AD requires installing software version 8.2.Q1 to the engine ECU, which increases the engine's margin to flameout. This AD results from reports of engine flameout events during flight, including reports of events where all engines simultaneously experienced a flameout or other adverse operation. Though the root cause investigation is not yet complete, we believe exposure to ice crystals during flight is associated with these flameout events. We are issuing this AD to provide increased margin to flameout, which will minimize the potential of an all-engine flameout event caused by ice accretion and shedding during flight.
Petition for Exemption; Summary of Petition Received
This notice contains a summary of a petition seeking relief from specified requirements of 14 CFR. The purpose of this notice is to improve the public's awareness of, and participation in, this aspect of FAA's regulatory activities. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of any petition or its final disposition.
Proposed Modification and Establishment of Restricted Areas and Other Special Use Airspace, Adirondack Airspace Complex; Fort Drum, NY
This action proposes to restructure the restricted areas located in the vicinity of Fort Drum, NY. The Air National Guard (ANG) proposed to redesign the airspace, referred to as the Adirondack Airspace Complex, by making a minor modification to the ceiling of existing restricted area R-5201, and by establishing two new restricted areas: R-5202A and R-5202B. In addition, the ANG proposes to redesign the Military Operations Areas (MOA) associated with the Fort Drum restricted areas. MOAs are not regulatory airspace, but are established administratively. Because the MOAs form an integral part of the Adirondack Airspace Complex, the FAA is also seeking comment on the proposed MOA changes through this NPRM. The ANG proposes these airspace changes to provide additional special use airspace (SUA) needed to conduct high altitude, long-range weapons releases and to allow more realistic training in modern tactics to be conducted in the Adirondack Airspace Complex.
