PROPOSED RULES

Airworthiness Directives; the Boeing Company Airplanes [FR DOC# 2013-18511] SUMMARY: We are revising an earlier proposed airworthiness directive (AD) for all The Boeing Company Model 767 airplanes. That NPRM proposed to require repetitive operational tests of the engine fuel suction feed of the fuel system, and other related testing if necessary. That NPRM was prompted by reports of two in-service occurrences on Model 737-400 airplanes of total loss of boost pump pressure of the fuel feed system, followed by loss of fuel system suction feed capability on one engine, and in-flight shutdown of the engine. This action revises that NPRM by proposing to revise the maintenance program to incorporate a revision to the Airworthiness Limitations Section of the maintenance planning data (MPD) document, and to remove airplanes from the applicability. We are proposing this supplemental NPRM to detect and correct failure of the engine
fuel suction feed capability of the fuel system, which could result in dual engine flameout, inability to restart the engines, and consequent forced landing of the airplane. Since these actions impose an additional burden over that proposed in the previous NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.

Airworthiness Directives; Airbus Airplanes [FR DOC# 2013-18556] SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A300 B4-600 and A300 B4-600R series airplanes. This proposed AD was prompted by reports of cracks found in the bottom wing skin stringers at rib 14 during full-scale fatigue testing
and in service. This proposed AD would require modifying the profile of stringer run-outs at rib 14 of both wings, including a high frequency eddy current inspection of the fastener holes for defects and repair if necessary. We are proposing this AD to prevent cracking in the bottom wing skin stringers, which could result in reduced structural integrity of the wings.

Airworthiness Directives; The Boeing Company Airplanes [FR DOC# 2013-18507] SUMMARY: We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 727 airplanes. This proposed AD was prompted by reports indicating that a standard fuel tank access door was located where an impact-resistant access door was
required, and stencils were missing from some impact-resistant access doors. This proposed AD would require an inspection of the left- and right-hand wing fuel tank access doors to determine that impact-resistant access doors are installed in the correct locations, and to replace any door with an impact-resistant access door if necessary. This proposed AD also would require an inspection for stencils and index markers on impact-resistant access doors, and application of new stencils or index markers if necessary. This proposed AD would also require revising the maintenance program to incorporate changes to the airworthiness limitations section. We are proposing this AD to prevent foreign object penetration of the fuel tank, which could cause a fuel leak near an ignition source (e.g., hot brakes), consequently leading to a fuel-fed fire.

Airworthiness Directives; The Boeing Company Airplanes [FR DOC# 2013-18564] SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 747-400 airplanes. This proposed AD was prompted by reports of fasteners missing on an airplane undergoing a passenger-to-freighter conversion. This proposed AD would require doing a general visual inspection of the station 1920 splice clip for correct fastener installation, and related investigative and corrective actions if necessary. We are proposing this AD to detect and correct missing or incorrect fasteners, which can lead to cracking and loss of load carrying capacity, resulting in a possible decompression event.

Airworthiness Directives; Airbus Airplanes [FR DOC# 2013-18566] SUMMARY: We propose to adopt a new airworthiness directive (AD) for all Airbus Model A330-300 series airplanes and Model A340-200 and -300 series airplanes. This proposed AD was prompted by reports of corrosion found on certain trimmable horizontal stabilizer
actuators (THSA), affecting the ballscrew lower splines between the tie bar and the screw-jack. This proposed AD would require repetitive detailed inspections for corrosion of certain THSAs, ballscrew integrity tests if necessary; and replacing any affected THSA with a serviceable or new and improved THSA, if necessary. We are proposing this AD to
detect and correct corrosion of the THSAs, which could lead, in the case of ballscrew rupture, to the loss of transmission of THSA torque loads from the ballscrew to the tie-bar, prompting THSA blowback, and possibly resulting in loss of control of the airplane.
RULES

Amendment of Class D and E Airspace, and Establishment of Class E Airspace; Oceana NAS, VA [FR DOC# 2013- 18398] SUMMARY: This action amends the Class D and Class E airspace operating hours, and establishes Class E surface airspace at Oceana Naval Air Station, (NAS), VA, due to the Air Traffic Control Tower at Oceana NAS (Apollo
Soucek Field) now operating on a part time basis. This action enhances the safety andairspace management of Instrument Flight Rules (IFR) operations at the airport. This action also updates the geographic coordinates of Oceana NAS (Apollo Soucek Field) and NALF Fentress.
