Public Notice for Waiver of Aeronautical Land-Use Assurance
The FAA is considering a proposal to change 5.69 acres of airport land from aeronautical use to non-aeronautical use and to authorize the lease of airport property located at Minneapolis-St. Paul International Airport, Minneapolis, Minnesota. The aforementioned land is not needed for aeronautical use. The subject property is located to the southeast of United States Post Office and south of the Terminal 1 inbound and outbound roadways located at Minneapolis-St. Paul International Airport, Minneapolis, Minnesota. The subject property does not currently have a designated use. The proposed non-aeronautical use of the property is for the construction of a hotel.
IFR Altitudes; Miscellaneous Amendments
This amendment adopts miscellaneous amendments to the required IFR (instrument flight rules) altitudes and changeover points for certain Federal airways, jet routes, or direct routes for which a minimum or maximum en route authorized IFR altitude is prescribed. This regulatory action is needed because of changes occurring in the National Airspace System. These changes are designed to provide for the safe and efficient use of the navigable airspace under instrument conditions in the affected areas.
Airworthiness Directives; BRP-Powertrain GmbH & Co KG Reciprocating Engines
We are adopting a new airworthiness directive (AD) for certain BRP-Powertrain GmbH & Co KG Rotax 912 F2, 912 F3, 912 F4, 912 S2, 912 S3, 912 S4, 914 F2, 914 F3, and 914 F4 reciprocating engines. This AD requires re-identification of the engine model and concurrent modification of the aircraft to indicate the maximum coolant temperature limit. This AD was prompted by a design change introduced by the manufacturer that relocated the engine cylinder head temperature sensor to a different location and converted it to a coolant temperature sensor. We are issuing this AD to prevent exceeding engine coolant temperature limits, which could result in loss of engine coolant, damage to the engine, and loss of control of the airplane.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are superseding Airworthiness Directive (AD) 2016-08-05 for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, Model CL-600-2D24 (Regional Jet Series 900) airplanes, and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. AD 2016-08-05 required replacement of affected angle of attack (AOA) transducers. This new AD requires the same actions as AD 2016-08-05. This new AD was prompted by a report of a typographical error in the regulatory text of AD 2016-08-05. We are issuing this AD to detect and replace incorrectly calibrated AOA transducers; incorrect calibration of the transducers could result in late activation of the stick pusher.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are superseding Airworthiness Directive (AD) 2016-09-04 for certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. AD 2016-09-04 required replacement of incorrectly calibrated angle of attack (AOA) transducers. This new AD requires the same actions as AD 2016-09-04. This new AD was prompted by a report of a typographical error in the regulatory text of AD 2016-09-04. We are issuing this AD detect and replace incorrectly calibrated AOA transducers; incorrect calibration of the transducers could result in late activation of the stick pusher.
Airworthiness Directives; Airbus Helicopters (Previously Eurocopter France) Helicopters
We are superseding Airworthiness Directive (AD) 2000-05-17 and AD 2001-04-12, which apply to Eurocopter France (now Airbus Helicopters) Model EC120B helicopters. AD 2000-05-17 and AD 2001-04-12 required repetitive visual checks of the engine-to-main gearbox (MGB) coupling tube assembly (coupling tube) for a crack and replacing any cracked tube with an airworthy tube. This new AD requires removing certain engine mount parts from service, measuring the height of the engine mounting base for certain helicopters, replacing the engine mount if a certain height is exceeded, inspecting the flared coupling on certain helicopters for a crack, and replacing the coupling if it is cracked. Since we issued AD 2000-05-17 and AD 2001-04-12, there have been reports of additional cracks in coupling tubes. These actions are intended to prevent coupling tube failure, loss of engine drive, and a subsequent forced landing of the helicopter.
Airworthiness Directives; Embraer S.A. Airplanes
We are adopting a new airworthiness directive (AD) for all Embraer S.A. Model ERJ 170 airplanes; and all Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. This AD was prompted by reports of cracks in certain engine low-stage bleed check valves. This AD requires replacing the air management system (AMS) controller operation program of the AMS controller processor boards, and replacing the current low-stage bleed check valve and associated seals. We are issuing this AD to prevent failure of the low-stage bleed check valve; simultaneous failures of both low-stage bleed check valves could result in a dual engine in- flight shutdown.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This AD was prompted by a report that certain center and outboard stowage bin modules were incorrectly installed. This AD requires an inspection of the center and outboard stowage bin modules for missing parts, quick release pins that are not fully engaged, and parts that are installed in incorrect locations; and corrective actions if necessary. We are issuing this AD to detect and correct incorrectly installed center and outboard stowage bin modules that might not remain intact during an emergency landing, resulting in injuries to occupants and interference with airplane evacuation.
