Licensing and Safety Requirements for Launch
This action corrects reference errors that appeared in a final rule the FAA published in the Federal Register on August 25, 2006. The final rule amended commercial space transportation regulations governing the launch of expendable launch vehicles. In that final rule, the FAA inadvertently referenced incorrect sections. The intent of this action is to correct this minor error in the regulation to ensure the requirement is clear and accurate.
Airworthiness Directives; General Electric Company (GE) CT58 Series Turboshaft Engines
The FAA is adopting a new airworthiness directive (AD) for certain GE CT58 series turboshaft engines. This AD requires recalculating the lives of certain part numbered compressor spools using a new repetitive heavy lift (RHL) multiplying factor. This AD results from reports of cracks originating from the inner faces of the locking screw holes in the compressor spool. We are issuing this AD to prevent cracks due to RHL missions. Cracks could result in an uncontained rotor burst and damage to, or loss of, the helicopter and serious injuries to any person onboard.
