Airworthiness Directives; Honeywell International Inc. Turboprop and Turboshaft Engines
We propose to adopt a new airworthiness directive (AD) for certain Honeywell International Inc. TPE331 turboprop and TSE331 turboshaft engines. This proposed AD was prompted by recent reports of failures of the direct drive fuel control gears and bearings in the hydraulic torque sensor gear assembly, part number (P/N) 3101726-3. This proposed AD would require initial and repetitive engine oil filter sampling and analysis of the affected engines. This proposed AD would also require inspection of hydraulic torque sensor gear assemblies that do not meet oil filter inspection requirements. This proposed AD would further require improved component overhaul procedures that would remove from service, by attrition, certain P/N hydraulic torque sensor gear assemblies. We are proposing this AD to correct the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc., Airplanes
We propose to adopt a new airworthiness directive (AD) 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. This proposed AD was prompted by a report of rudder yoke components that had not been properly inspected at the supplier. This proposed AD would require replacement of the left and right rudder yoke assemblies. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc., Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), Model CL-600-2D15 (Regional Jet Series 705), Model CL-600- 2D24 (Regional Jet Series 900), and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This proposed AD was prompted by a report of a smoke-in-cabin event due to a non-sustaining electrical fire. This proposed AD would require installation of protective sleeves on the bonding jumper wires of affected galleys and lavatories. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Airplanes
We are superseding Airworthiness Directive (AD) 2017-13-12, which applied to all Airbus Model A318 and A319 series airplanes; Model A320-211, -212, -214, -231, -232, and -233 airplanes; and Model A321- 111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2017- 13-12 required modification or replacement of certain side stay assemblies of the main landing gear (MLG). This new AD clarifies the formatting of a figure in the published version of AD 2017-13-12. This new AD was prompted by reports indicating that affected parties misinterpreted the applicability of the affected part numbers due to the formatting of a figure in the published version of AD 2017-13-12, which could result in a negative effect on compliance. We are issuing this AD to address the unsafe condition on these products.
Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments
This rule amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide for the safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
