Federal Aviation Administration May 26, 2015 – Federal Register Recent Federal Regulation Documents

This action modifies the designated altitudes of restricted area R-4501B, Fort Leonard Wood, MO, by raising the restricted area ceiling from 1,500 feet mean seal level (MSL) in the north and 2,200 feet MSL in the south to a single altitude of 4,300 feet MSL across the entire restricted area. This action also adds exclusions to the boundaries of R-4501C, R-4501F, and R-4501H to address overlapping restricted areas. Finally, this action makes administrative changes to the R-4501A and R-4501B titles and to R-4501A-D, R-4501F, and R-4501H using agency information to standardize the format and information describing these restricted areas of the Fort Leonard Wood restricted area complex.

We propose to adopt a new airworthiness directive (AD) for British Aerospace Regional Aircraft Model Jetstream Model 3201 airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as the in- service special detailed inspection technique required for the Jetstream 3200's life extension program was delayed; consequently, the in-service special detailed inspection technique is not formally part of the life extension program and may therefore not be accomplished as intended. We are issuing this proposed AD to require actions to address the unsafe condition on these products.

This action amends Class E Airspace at Clarksburg, WV, as the Clarksburg VOR/DME has been decommissioned, requiring airspace redesign at North Central West Virginia Airport, formerly Benedum Airport. This action enhances the safety and management of Instrument Flight Rules (IFR) operations at the airport. This action also updates the geographic coordinates of the airport.

This action removes Class E Airspace at Lexington, TN, as the Franklin Wilkins Airport has been abandoned, and controlled airspace is no longer required. This action enhances the safety and airspace management around the Lexington, TN, area.
