Special Conditions: Pratt and Whitney Canada, PW210A; Flat 30-Second and 2-Minute One Engine Inoperative Rating
This action proposes special conditions for the Pratt and Whitney Canada PW210A engine model. This engine will have a novel or unusual design featurean additional one engine inoperative (OEI) rating that combines the 30-second and 2-minute OEI ratings into a single rating. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

Airworthiness Directives; Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model 188 series airplanes. This proposed AD was prompted by an evaluation by the design approval holder (DAH) indicating that a certain circumferential fuselage splice is subject to widespread fatigue damage (WFD). This proposed AD would require an inspection for corrosion and previous repairs, severed stringers, cracking, and loose or distressed fasteners of the forward and aft ends of the stringer splices of certain stringers, inspection for cracking and modification of certain fastener holes common to the stringer and splice member at the forward and aft ends of the splice, and related investigative and corrective actions if necessary. We are proposing this AD to prevent loss of residual strength of a certain circumferential fuselage splice, which could lead to rapid decompression of the cabin and potential loss of the airplane.
Changes to the Application Requirements for Authorization to Operate in Reduced Vertical Separation Minimum Airspace
This action would revise the FAA's requirements for an application to operate in Reduced Vertical Separation Minimum (RVSM) airspace. This proposal would eliminate the burden and expense of developing, processing, and approving RVSM maintenance programs. As a result of this proposed revision, an applicant to operate in RVSM airspace would no longer be required to develop and submit an RVSM maintenance program solely for the purpose of an RVSM authorization. Because of other, independent FAA airworthiness regulations, all aircraft operators would nevertheless continue to be required to maintain RVSM equipment in an airworthy condition.
Airworthiness Directives; Turbomeca S.A. Turboshaft Engines
We are superseding airworthiness directive (AD) 2014-01-01 for all Turbomeca S.A. Arrius 2F turboshaft engines. AD 2014-01-01 required a one-time inspection of the ejector assembly nozzle of certain serial number (S/N) lubricating devices and, if a discrepancy was found, removal and replacement of the affected ejector assembly nozzle with a part eligible for installation. This AD requires the same action as AD 2014-01-01 and expands the list of affected S/N lubricating devices. This AD was prompted by the determination that additional lubricating devices, identifiable by S/N, may have an incorrect bonding of the nozzle on the ejector assembly. We are issuing this AD to prevent failure of the ejector assembly nozzle, which could lead to an in- flight shutdown (IFSD) of the engine, damage to the engine, and damage to the helicopter.
Airworthiness Directives; Lycoming Engines Reciprocating Engines (Type Certificate Previously Held by Textron Lycoming Division, AVCO Corporation)
We are adopting a new airworthiness directive (AD) for certain Lycoming TIO-540-AJ1A reciprocating engines. This AD was prompted by several reports of cracked engine exhaust pipes. This AD requires inspection of the engine exhaust pipes for cracks and replacement of the turbocharger mounting bracket. We are issuing this AD to prevent failure of the exhaust system due to cracking, which could lead to uncontrolled engine fire, harmful exhaust gases entering the cabin resulting in crew incapacitation, and damage to the airplane.
Airworthiness Directives; Zodiac Seats France (Formerly Sicma Aero Seat) Passenger Seat Assemblies
We are superseding Airworthiness Directive (AD) 2014-20-11, for Zodiac Seats France 9140, 9166, 9173, 9174, 9184, 9188, 9196, 91B7, 91B8, 91C0, 91C2, 91C4, 91C5, 91C9, 9301, and 9501 series passenger seat assemblies. AD 2014-20-11 required a general visual inspection for cracking of backrest links; replacement with new links if cracking is found; and eventual replacement of all links with new links. This AD was prompted by a determination that a model designation specified in paragraph (c)(1) of that AD was incorrect. This new AD identifies the correct model designation. We are issuing this AD to detect and correct cracks in the backrest links, which could affect the structural integrity of seat backrests. Failure of the backrest links could result in injury to an occupant during emergency landing conditions.
