Airworthiness Directives; Pratt & Whitney Division Turbofan
We are superseding Airworthiness Directive (AD) 2017-12-03 for certain Pratt & Whitney Division (PW) PW2037, PW2037M, and PW2040 turbofan engines. AD 2017-12-03 required installing a software standard eligible for installation and precludes the use of electronic engine control (EEC) software standards earlier than SCN 5B/I. This AD requires installing a software standard eligible for installation and preclude the use of EEC software standards earlier than SCN 5B/I or SCN 27A. This AD was prompted by an unrecoverable engine in-flight shutdown (IFSD) after an ice crystal icing event. We are issuing this AD to address the unsafe condition on these products.
Proposed Establishment of Class E Airspace; Maurice, IA
This action proposes to establish Class E airspace extending upward from 700 feet above the surface at Sioux County Regional Airport, Maurice, IA. Controlled airspace is necessary to accommodate new standard instrument approach procedures developed at Sioux County Regional Airport, for the safety and management of instrument flight rules (IFR) operations.
Airworthiness Directives; Dassault Aviation Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model MYSTERE-FALCON 50, MYSTERE-FALCON 900, and FALCON 900EX airplanes. This proposed AD was prompted by reports of cracked reinforcing straps (doublers) on the ailerons of airplanes equipped with blended winglets. This proposed AD would require repetitive detailed inspections for cracking of the upper and lower reinforcing straps on the ailerons, and replacement if necessary. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A330-200 series airplanes; Model A330-200 Freighter series airplanes; and Model A330-300 series airplanes. This proposed AD was prompted by revisions to certain airworthiness limitation item (ALI) documents, which specify more restrictive instructions and/or airworthiness limitations. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate new or more restrictive instructions and/or airworthiness limitations. We are proposing this AD to address the unsafe condition on these products.
