This action proposes to modify Class E surface area airspace, modify Class E airspace extending upward from 700 feet, and establish Class E airspace designated as an extension at Arcata Airport, Arcata, CA. The action also proposes to modify Class E airspace extending upward from 700 feet at Rohnerville Airport, Fortuna, CA, and establish stand-alone Class E airspace extending upward from 700 feet at Murray Field Airport, Eureka, CA, to accommodate airspace redesign for the safety and management of Instrument Flight Rules (IFR) operations within the National Airspace System. Additionally, this proposal would update the geographic coordinates of these airports.

This action proposes to modify Class E airspace extending upward from 700 feet above the surface at Evansville Regional Airport, Evansville, Indiana. This action is necessary due to the decommissioning of the Evansville non-directional radio beacon (NDB) and cancellation of the NDB approach. This action would also update the geographic coordinates of the airport, as well as Skylane Airport, listed with Evansville Regional Airport in Class C airspace.

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-300, -400, and -500 series airplanes. This AD was prompted by reports of cracks in the horizontal stabilizer lower skins. This AD requires inspections for cracking of the horizontal stabilizer lower skin, and corrective actions if necessary; and also provides actions that would terminate certain repetitive inspections. We are issuing this AD to address the unsafe condition on these products.
