Amendment of VOR Federal Airways; Northeastern United States
Document Number: 2015-13980
Type: Rule
Date: 2015-06-09
Agency: Federal Aviation Administration, Department of Transportation
This action amends VOR Federal Airways V-31, V-36, V-98, V-164 and V-252 by removing from the route descriptions, those segments that extend into and/or through Canadian airspace. This action is necessary to match route changes made by Canada as part of the Windsor-Toronto- Montreal (W-T-M) project. The route segments in Canada are no longer in effect; therefore, the United States has issued Notices to Airmen (NOTAM) identifying the affected segments as ``not authorized'' pending the deletion of the segments from the route descriptions through this rulemaking action.
Airworthiness Directives; British Aerospace Regional Aircraft Airplanes
Document Number: 2015-13918
Type: Proposed Rule
Date: 2015-06-09
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for British Aerospace Regional Aircraft Jetstream Series 3101 and Jetsream Model 3201 airplanes. 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 missing countersunk washers under the head of the main landing gear trunnion cap tension bolts that could cause fatigue in the bolt shanks. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; MD Helicopters Inc.
Document Number: 2015-13853
Type: Proposed Rule
Date: 2015-06-09
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for MD Helicopters Inc. (MDHI) Model 500N and 600N helicopters with certain rotating cone assemblies installed. This proposed AD would require establishing a life limit of 10,000 hours time-in-service (TIS) on these rotating cone assemblies. This proposed AD is prompted by the determination that MDHI created rotating cone assemblies with new dash numbers but incorrectly failed to identify them as life-limited parts. The proposed actions are intended to prevent operation of rotating cone assemblies past their life limits, failure of the rotating cone assemblies, loss of directional control, and subsequent loss of control of the helicopter.

Type: Rule
Date: 2015-06-09
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for Sikorsky Aircraft Corporation (type certificate previously held by Schweizer Aircraft Corporation) (Sikorsky) Model 269D and Model 269D Configuration A helicopters. This AD requires reducing the life limit of the ring gear carrier assembly. This AD was prompted by cracks in the ring gear carrier assembly. The actions are intended to reduce the life of the ring gear carrier assembly to prevent failure of the main rotor transmission, loss of engine power to the main rotor, and subsequent loss of control of the helicopter.
Airworthiness Directives; Agusta S.p.A. (Agusta) Helicopters
Document Number: 2015-13845
Type: Rule
Date: 2015-06-09
Agency: Federal Aviation Administration, Department of Transportation
We are superseding airworthiness directive (AD) 2014-02-08 for Agusta Model A109C, A109S, A109K2, A109E, and AW109SP helicopters. AD 2014-02-08 required inspecting the lock wires securing the tail rotor (T/R) duplex bearing locking nut (locking nut) to determine whether any lock wires are missing or damaged. This AD retains some of the requirements of AD 2014-02-08 but removes the terminating action, expands the applicability, and adds a daily pilot check. This AD was prompted by reports of loosening T/R locking nuts. These actions are intended to prevent failure of the T/R and subsequent loss of control of the helicopter.
Airworthiness Directives; Sikorsky Aircraft Corporation (Sikorsky) Model Helicopters
Document Number: 2015-13844
Type: Rule
Date: 2015-06-09
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for Sikorsky Model S-92A helicopters. This AD requires installing a main gearbox (MGB) failed pump sensor and vacuum switch wiring, installing an MGB oil auto bypass system, activating Aircraft Management System (AMS) 7.1 software to show a new visual warning, and installing updated enhanced ground proximity warning system (EGPWS) software that includes an aural annunciation of a complete oil pressure loss condition. This AD also requires inserting a Rotorcraft Flight Manual (RFM) Supplement into the applicable RFM. This AD was prompted by investigation results of in- service oil leakage incidents. The actions are intended to alert and prevent MGB oil loss, which could lead to failure of the MGB and subsequent loss of control of the helicopter.
Airworthiness Directives; Agusta S.p.A. Helicopters
Document Number: 2015-13343
Type: Rule
Date: 2015-06-09

We are adopting a new airworthiness directive (AD) for certain Agusta S.p.A. Model AB412 and AB412 EP helicopters. This AD requires inspecting the tail rotor (T/R) drive shaft flanged adapter (adapter) for a crack and removing the adapter from service if there is a crack. This AD is prompted by a report of a crack found in an adapter. These actions are intended to detect a crack in the adapter and prevent failure of the T/R drive shaft, which could result in reduced control of the helicopter.
Airworthiness Directives; Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Airplanes
Document Number: 2015-13325
Type: Rule
Date: 2015-06-09
Agency: Federal Aviation Administration, Department of Transportation
We are superseding Airworthiness Directive (AD) 95-26-11 for all Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model L-1011 series airplanes. AD 95-26-11 required repetitive inspections to detect cracking of the fittings that attach the aft pressure bulkhead to the fuselage stringers, repetitive inspections to detect cracking of the fittings and of the splice tab of the aft pressure bulkhead, and corrective actions if necessary. This new AD requires repetitive inspections to detect cracking of the fittings that attach the aft pressure bulkhead to the fuselage stringers, repetitive inspections to detect cracking of the fittings and of the splice tab of the aft pressure bulkhead, repetitive inspections for cracking of certain aft fuselage skin panels, a structural modification, a post- modification inspection program, and corrective actions if necessary. This AD was prompted by a determination that the fittings at stringer attachments to the upper region of the aft pressure bulkhead are subject to widespread fatigue damage (WFD). We are issuing this AD to prevent simultaneous failure of multiple stringer end fittings through fatigue cracking at the aft pressure bulkhead, which could lead to rapid decompression of the airplane.
Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes

Date: 2015-06-09
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain ATR-GIE Avions de Transport R[eacute]gional Model ATR42 and ATR72 airplanes. This AD was prompted by reports of fuel quantity indication malfunctions caused by fuel probe failure. This AD requires identifying the part number and serial number of the fuel probes, and replacing the fuel probes if necessary. We are issuing this AD to prevent fuel probe failure, which could lead to undetected fuel starvation and consequent dual engine in-flight flame-out.
Airworthiness Directives; Bombardier, Inc. Airplanes
Document Number: 2015-11389
Type: Rule
Date: 2015-06-09
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-400 series airplanes. This AD was prompted by reports of hydraulic fluid loss from the reservoir of the main landing gear (MLG) alternate extension system. This AD requires inspection for correct assembly of the MLG alternate extension system reservoir lid, and corrective action if necessary. We are issuing this AD to, in the event of a failure of the primary MLG extension system, prevent failure of the alternate MLG extension system to fully extend the MLG into a down-and-locked position, which could result in collapse of both left-hand and right-hand MLG sides during touchdown.
