The FAA proposes to adopt a new airworthiness directive (AD) for all Pratt & Whitney Canada Corp. (P&WC) Model PW307D engines. This proposed AD was prompted by a root cause analysis of an event involving an uncontained failure of a high-pressure turbine (HPT) 1st-stage disk, on an International Aero Engines AG Model V2533-A5 engine, that resulted in high-energy debris penetrating the engine cowling and an aborted takeoff. This proposed AD would require removing certain HPT 2nd-stage disks from service and would also prohibit installation of certain HPT 2nd-stage disks on any affected engine. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is considering a proposal to change 12.53 acres of airport land from aeronautical use to non-aeronautical use and to authorize the lease of airport property located at Lake County Executive Airport, Willoughby, Ohio. The aforementioned land is not needed for aeronautical use. The property is located east of Lost Nation Road and north of Jet Center Place, adjacent to the Lost Nation Sports Park. The property is designated as aeronautical use however the existing use and proposed future use as a soccer field is non- aeronautical.

This action amends Class E airspace extending upward from 700 feet above the surface for Bomar Field/Shelbyville Municipal Airport, Shelbyville, Tennessee, as an airspace evaluation determined an update for this airport necessary.

In addition, this action removes the Shelbyville VOR/DME from the description and updates the description header.

FMCSA requests public comment on an application for exemption from the Great Lakes Timber Professionals Association (GLTPA) to allow motor carriers to use fewer tiedowns than required by the regulations for securing shortwood logs transported lengthwise in crib-type vehicles that have been modified or manufactured without front structures, without rear structures, or with a center-mounted crane for loading and unloading. GLTPA and the Wisconsin State Patrol Motor Carrier Enforcement Section partnered to conduct cargo securement testing on stacks of shortwood logs in a crib-type vehicle using different tiedown configurations. Based on this testing, GLTPA proposes alternative cargo securement methods for shortwood logs loaded lengthwise and states that such securement methods will maintain a level of safety that is equivalent to, or greater than, the level of safety achieved without the exemption.

This action revokes Alaskan Very High Frequency (VHF) Omnidirectional Range (VOR) Federal Airway V-489. The FAA is taking this action due to automated flight plan conflicts between New York Air Route Traffic Control Center (ARTCC) and Anchorage ARTCC when pilots file V-489 in flight plans.
