Federal Aviation Administration May 19, 2009 – Federal Register Recent Federal Regulation Documents

This action proposes to amend Class E airspace at Monee, IL. Additional controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAPs) at Bult Field Airport, Monee, IL. This action would also reflect the name change of the airport from Sanger Airport to Bult Field Airport and update the geographic coordinates. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations for SIAPs at Bult Field Airport.

The FAA is adopting a new airworthiness directive (AD) for CFM International S.A. CFM56-2, CFM56-3, CFM56-5A, CFM56-5B, CFM56-5C, and CFM56-7B series turbofan engines with certain part number (P/N) and serial number (SN) high-pressure compressor (HPC) 4-9 spools installed. This AD requires removing certain HPC 4-9 spools listed by P/N and SN in this AD. This AD results from reports of certain HPC 4-9 spools that Propulsion Technology LLC (PTLLC) improperly repaired and returned to service. We are issuing this AD to prevent cracking of the HPC 4-9 spool, which could result in possible uncontained failure of the spool and damage to the airplane.
