Regulation of Fractional Aircraft Ownership Programs and On-Demand Operations; Technical Amendment
The FAA is amending its regulations governing operations of aircraft in fractional ownership programs. This document corrects a technical error in the codified text of the regulations.
Airworthiness Directives; L'Hotellier Portable Halon 1211 Fire Extinguishers
This amendment adopts a new airworthiness directive (AD) for the specified fire extinguishers. This action requires replacing each unairworthy portable fire extinguisher with an airworthy portable fire extinguisher. This amendment is prompted by an ongoing investigation that has established that unapproved Halon 1211 has been used to fill L'Hotellier portable fire extinguishers that are likely to be onboard various model helicopters. The actions specified in this AD are intended to prevent using contaminated gas that may reduce fire suppression and release toxic fumes that would endanger the safety of the helicopter and its occupants.
Amendment of Class E Airspace; Mosby, MO
This action amends Class E airspace for Mosby, MO. Decommissioning of the Mosby non-directional beacon (NDB) at Midwest National Air Center Airport, Mosby, MO, has made this action necessary to enhance the safety and management of Instrument Flight Rule (IFR) operations at the airport.
Amendment of Class D Airspace; Corpus Christi, TX
This action amends Class D airspace within the Corpus Christi, TX, area by updating the geographic coordinates for Cabaniss Navy Outlying Field (NOLF). This action does not change the boundaries or operating requirements of the airspace.
Airworthiness Directives; Viking Air Limited Model DHC-3 (Otter) Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above that are equipped with a Honeywell TPE331-10 or - 12JR turboprop engine installed per Supplemental Type Certificate (STC) SA09866SC. This AD requires incorporating revised airspeed limitations and marking the airspeed indicator accordingly. There is also a requirement for the installation of a temporary placard until the airspeed indicator can be modified but not to exceed a certain period of time. This AD was prompted by analysis that showed that airspeed limitations for the affected airplanes are not adjusted for the installation of a turboprop engine as stated in the regulations. We are issuing this AD to prevent the loss of airplane structural integrity due to the affected airplanes being able to operate at speeds that exceed the speeds established in the Federal aviation regulations for safe operation.
Airworthiness Directives; Sikorsky Aircraft Corporation (Sikorsky) Model S-92A Helicopters
We are adopting a new airworthiness directive (AD) for the Sikorsky Model S-92A helicopters. This AD requires a nondestructive inspection (NDI), eddy current or fluorescent penetrant inspection (FPI), of each main gearbox (MGB) upper housing assembly rib on the left, right, and forward MGB mounting foot at specified intervals based on the MGB upper housing assembly hours time-in-service (TIS). If there is a crack, this AD requires replacing the MGB upper housing assembly with an airworthy MGB upper housing assembly. This AD is prompted by a report of a crack found on the MGB upper housing assembly left mounting foot forward rib that cannot be detected visually. We are issuing this AD to prevent loss of the MGB and subsequent loss of control of the helicopter.
Airworthiness Directives; Koito Industries, Ltd., Seats and Seating Systems Approved Under Technical Standard Order (TSO) TSO-C39b, TSO-C39c, or TSO-C127a
We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires determining if affected seats and seating systems and their components are compliant with certain FAA regulations, and removing those seats, seating systems, and their components that are shown to be unsafe from the affected fleet. This AD was prompted by a determination that the affected seats and seating systems may not meet certain flammability, static strength, and dynamic strength criteria. Failure to meet static and dynamic strength criteria could result in injuries to the flightcrew and passengers during emergency landing conditions. In the event of an in-flight or post- emergency landing fire, failure to meet flammability criteria could result in an accelerated fire. We are issuing this AD to prevent accelerated fires and injuries to the flightcrew and passengers.
