Notice of Intent To Rule on Change in Use of Aeronautical Property at Louisville International Airport, Louisville, Kentucky
The Federal Aviation Administration (FAA) is requesting public comment on a request by the Louisville Regional Airport Authority of Louisville, Kentucky, owner of the Louisville International Airport, to change a portion of airport property from aeronautical to non- aeronautical use at the Louisville International Airport. The request consists of approximately 0.91 acres to the Commonwealth of Kentucky for use as right-of-way for the relocated portion of Grade Lane. This action is taken under the provisions of Section 125 of the Wendell H. Ford Aviation Investment Reform Act for the 21st Century (AIR 21).
Special Conditions: Pratt and Whitney Canada, PW210A; Flat 30-Second and 2-Minute One Engine Inoperative Rating
These special conditions are issued 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 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; Technify Motors GmbH Reciprocating Engines
We propose to adopt a new airworthiness directive (AD) for all Technify Motors GmbH TAE 125-02 reciprocating engines with a dual mass flywheel installed. This proposed AD was prompted by reports of a gearbox drive shaft breaking during starting or restarting of the engine. This proposed AD would require installation of a start phase monitoring system and associated specified software. We are proposing this AD to prevent overload and failure of the gearbox drive shaft, which could lead to failure of the engine, in-flight shutdown, and loss of control of the airplane.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A318, A319, and A321 series airplanes. This proposed AD was prompted by reports of in-flight loss of fixed and hinged main landing gear (MLG) fairings, and reports of post-modification MLG fixed fairing assemblies that have wear and corrosion. This proposed AD would require, for certain airplanes, repetitive replacements of the fixed fairing upper and lower attachment studs of both the right-hand (RH) and left-hand (LH) MLG; and repetitive inspections for corrosion, wear, fatigue, cracking, and loose studs of each forward stud assembly of the fixed fairing door upper and lower forward attachment of both RH and LH MLG; and replacement if necessary. This proposed AD also provides an optional terminating modification for the repetitive replacements of the fixed fairing upper and lower attachment studs. We are proposing this AD to prevent in-flight detachment of an MLG fixed fairing and consequent damage to the airplane.
