Proposed Establishment of Class E Airspace; Crandon, WI
This action proposes to establish Class E airspace at Crandon, WI. Controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAPs) at Crandon/Steve Conway Municipal Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations for SIAPs at the airport.
Proposed Establishment of Class E Airspace; Conway, AR
This action proposes to establish Class E airspace at Conway, AR. Controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAPs) at Cantrell Field. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations for SIAPs at the airport.
Notice of Request To Release Airport Property
The FAA proposes to rule and invites public comment on the release of land at the Sullivan Regional Airport, Sullivan, Missouri, under the provisions of 49 U.S.C. 47107(h)(2).
Airworthiness Directives; DASSAULT AVIATION Airplanes
We propose to adopt a new airworthiness directive (AD) for certain DASSAULT AVIATION Model FALCON 900EX airplanes. This proposed AD was prompted by our determination of the need for a revision to the airplane airworthiness limitations to introduce a corrosion prevention control program, among other changes, to the maintenance requirements and airworthiness limitations. This proposed AD would require revising the maintenance or inspection program, as applicable, to include the maintenance tasks and airworthiness limitations specified in the Airworthiness Limitations section of the airplane maintenance manual. We are proposing this AD to prevent reduced structural integrity of the airplane, and prevent reduced controllability of the airplane.
Amendment to Class B Airspace Area; Detroit, MI
This action corrects a final rule published in the Federal Register January 21, 2014. In that rule, the shared boundary between the Detroit Class B airspace Area A and Area B subareas did not match, as originally intended, in the regulatory text descriptions. This correction is necessary to close the unintended gap between subareas created by the boundary error and to ensure the accuracy of the charted Detroit Class B airspace area.
Airworthiness Directives; Pratt & Whitney Turbofan Engines
We are adopting a new airworthiness directive (AD) for all Pratt & Whitney (PW) PW2037, PW2037D, PW2037M, PW2040, PW2040D, PW2043, PW2146, PW2240, PW2337, PW2643, and F117-PW-100 turbofan engines. This AD was prompted by a rupture of the diffuser-to-high-pressure turbine (HPT) case flange. This AD requires a one-time eddy current inspection (ECI) of affected engines with certain diffuser and HPT cases installed. This AD also requires a fluorescent-penetrant inspection (FPI) of the diffuser case rear flange and HPT case front flange. We are issuing this AD to prevent failure of the diffuser-to-HPT case flange, which could lead to uncontained engine failure and damage to the airplane.
