Airport Improvement Program (AIP): Policy Regarding Access to Airports From Residential Property
This action adopts a Policy Statement, based on Federal law, concerning through-the-fence access to a federally-obligated airport from an adjacent or nearby property, when that property is used as a residence. This Policy Statement replaces FAA's previously published Interim Policy (76 FR 15028; March 18, 2011) with regard to commercial service airports, and establishes how FAA will implement section 136 of Public Law 112-95.
Airworthiness Directives; Eurocopter France Helicopters
We are publishing a new airworthiness directive (AD) for Eurocopter France Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, AS350D, AS350D1, AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters. This AD requires, before further flight, determining whether a single hydraulic main or tail rotor servo-control is installed on your helicopter. If a certain servo-control is installed, before the further flight, this AD requires replacing that servo-control. This AD was prompted by the discovery of excessive axial play detected on bearings installed on certain single hydraulic main and tail rotor servo-controls (servo-control). The excessive play could cause the distributor slide valve to jam in its sleeve. This condition could result in jamming the hydraulic flight controls, necessitating that the pilot cut off hydraulic power. This action would increase the pilot's workload, resulting in possible loss of helicopter control.
Airworthiness Directives; Pilatus Aircraft Ltd. Airplanes
We are adopting a new airworthiness directive (AD) for certain Pilatus Aircraft Ltd. Model PC-6/B2-H4 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as faulty rivets installed in the airframes during production could reduce the structural integrity of the airplane. We are issuing this AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; the Boeing Company Airplanes
We are superseding airworthiness directive (AD) 87-02-07, which applied to all The Boeing Company Model 737-100 and -200 series airplanes. AD 87-02-07 required replacement of certain underwing fuel tank access covers with stronger, fire-resistant covers. This new AD also requires inspecting fuel tank access doors to determine that impact-resistant access doors are installed in the correct locations, inspecting application of stencils and index markers of impact- resistant access doors, doing corrective actions if necessary, revising the maintenance program, and adding airplanes to the applicability. This AD was prompted by reports of standard access doors installed where impact-resistant access doors are required, and reports of impact-resistant doors without stencils. We are issuing this AD to prevent foreign object penetration of the wing tank, which could lead to a fuel leak near ignition sources (engine, hot brakes), consequently leading to a fuel-fed fire.
Airworthiness Directives; The Boeing Company Airplanes
We are superseding an existing airworthiness directive (AD) for certain The Boeing Company Model 767 airplanes. That AD currently requires sealing certain fasteners and stiffeners in the fuel tank, changing certain wire bundle clamp configurations on the fuel tank walls, inspecting certain fasteners in the fuel tanks and determining the method of attachment of the vortex generators; and performing corrective actions if necessary. This new AD adds a general visual inspection for the presence of a polytetrafluoroethylene (TFE) sleeve at the clamp location on the rear spar, and installation of a TFE sleeve if necessary. This new AD also adds airplanes to the applicability. This AD was prompted by fuel system reviews conducted by the manufacturer, and the identification of another possible ignition source location. We are issuing this AD to prevent possible ignition sources in the auxiliary (center) fuel tank, main fuel tanks, and surge tanks caused by a wiring short or lightning strike, which could result in fuel tank explosions and consequent loss of the airplane.
Airworthiness Directives; Eurocopter Deutschland GmbH Helicopters
We are adopting a new airworthiness directive (AD) for Eurocopter Deutschland GmbH (Eurocopter) Model MBB-BK 117 C-2 helicopters. This AD requires determining if a certain serial-numbered bevel gear is installed in the tailrotor intermediate gear box (IGB). If such a bevel gear is installed in the IGB, this AD requires recording the bevel gear's reduced life limit in the Airworthiness Limitations section of the maintenance manual and on the component history card or equivalent IGB record. If the bevel gear's life limit has been reached or exceeded, this AD requires, before further flight, replacing the bevel gear with an airworthy bevel gear. This AD is prompted by the discovery that the tooth foot fillets in certain bevel gears fall below the minimum dimensions required in the design documents to ensure safe functioning of the bevel gear until it reaches its approved life limit. This AD's actions are intended to prevent failure of a bevel gear before it reaches its currently approved life limit, failure of the IGB, and subsequent loss of helicopter control.
