Federal Aviation Administration March 11, 2016 – Federal Register Recent Federal Regulation Documents

The Federal Aviation Administration (FAA) announces the cancellation of Policy Statement Number PS-ANM100-1986-00051. The policy statement is cancelled because it was superseded by an advisory circular (AC) and is no longer necessary.

The Federal Aviation Administration (FAA) announces the cancellation of Policy Statement Number ANM-03-117-09. The policy statement is cancelled because it was superseded by an advisory circular (AC) and is no longer necessary.

We propose to adopt a new airworthiness directive (AD) for all Turbomeca S.A. MAKILA 2A and MAKILA 2A1 turboshaft engines. This proposed AD was prompted by two occurrences of crack initiation on a ferrule of the diffuser. This proposed AD would require repetitive diffuser inspections and replacement of those diffusers that fail inspection. We are proposing this AD to prevent rupture of the ferrule of the diffuser, which could result in engine fire and damage to the helicopter.

We propose to supersede airworthiness directive (AD) 2010-11- 10 that applies to all Turbomeca S.A., Astazou XIV B and XIV H turboshaft engines. AD 2010-11-10 requires inspection of certain third stage turbine wheels and removal of any damaged wheel. This AD was prompted by a report of a third stage turbine wheel crack detected during engine overhaul. This proposed AD would expand the population and frequency of repetitive inspections. We are proposing this AD to prevent uncontained failure of the third stage turbine wheel, which could result in damage to the engine and damage to the helicopter.

This action changes the effective date of a final rule published in the Federal Register of February 19, 2016, amending Class E surface area airspace, Class E airspace designated as an extension, and Class E airspace extending upward from 700 feet above the surface, in the Enid, OK, area to allow additional time for charting. This correction adds the part-time Notice to Airmen (NOTAM) language inadvertently removed from the Class E surface area description for Vance AFB, and Woodring Municipal Airport, Enid, OK. Adjustment of the geographic coordinates are also made to the Vance VHF Omnidirectional Range Tactical Air Navigation (VORTAC) listed in the Class E airspace area designated as an extension to the Class D surface area.

We propose to adopt a new airworthiness directive (AD) for certain Agusta Model AB139 and AW139 helicopters. This proposed AD would require performing operational checks of both hydraulic systems. This proposed AD is prompted by an assessment of the hydraulic systems of the helicopter following an accident. The proposed actions are intended to prevent loss of hydraulic power to the flight controls and subsequent loss of control of the helicopter.

This action proposes to modify Class D airspace, Class E airspace designated as surface areas, and Class E airspace extending upward from 700 feet above the surface at Antlers, OK; Oklahoma City, OK; Oklahoma City Wiley Post Airport, OK; and Shawnee, OK. The decommissioning of non-directional radio beacons (NDB) and/or cancellation of NDB approaches due to advances in Global Positioning System (GPS) capabilities have made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the above locations. This action also would note the updated airport names of David Jay Perry Airport, Goldsby, OK; El Reno Regional Airport, Shawnee Regional Airport, and Chandler Regional Airport to coincide with the FAA's aeronautical database. Additionally, this action would update the geographic coordinates for Tinker AFB, El Reno Regional Airport, Wiley Post Airport, Sundance Airpark, Seminole Municipal Airport, Prague Municipal Airport, Chandler Regional Airport, Tilghman NDB, Cushing Municipal Airport, Cushing NDB, and Cushing Regional Hospital Heliport to coincide with the FAA's aeronautical database.

We are adopting a new airworthiness directive (AD) for certain MDHI Model 369A (Army OH-6A), 369H, 369HE, 369HM, 369HS, 369D, 369E, 369F, 369FF, and 500N helicopters. This AD requires inspecting the auxiliary fuel pump (fuel pump) wire routing in the left-hand fuel cell and corrective action, if necessary. This AD also requires installing a warning decal on the left-hand fuel cell access cover. This AD was prompted by accidents resulting from incorrectly positioned fuel pump wiring within the fuel tank interfering with the operation of the fuel quantity sensor float, which caused an erroneous fuel quantity indication in the cockpit. The actions are intended to detect and correct routing of the fuel pump wiring to prevent interference with the fuel quantity sensor float, an erroneous fuel quantity indication in the cockpit, and subsequent fuel exhaustion and emergency landing.

We are superseding Airworthiness Directive (AD) 2013-08-23 for all The Boeing Company 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, MD-10- 30F, MD-11, and MD-11F airplanes. AD 2013-08-23 required adding design features to detect electrical faults and to detect a pump running in an empty fuel tank. This new AD would clarify certain requirements and remove a terminating action. This new AD would also provide an optional method of compliance for the proposed actions. This AD was prompted by a determination that it is necessary to clarify the requirements for the design features and to remove a terminating action for certain inspections. We are issuing this AD to reduce the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
