Department of Transportation April 11, 2012 – Federal Register Recent Federal Regulation Documents

This is a confirmation notice of the cancellation of TSO-C67, Airborne Radar Altimeter Equipment (For Air Carrier Aircraft). The effect of the cancelled TSO will result in no new TSO-C67 design or production approvals. However, cancellation will not affect any current production of an existing TSO authorization (TSOA). Articles produced under an existing TSOA can still be installed per the existing airworthiness approvals, and all applications for new airworthiness approvals will still be processed.

In this document, PHMSA is seeking comment on the impact of changes to the requirements for the air transport of lithium cells and batteries that have been adopted into the 2013-2014 International Civil Aviation Organization Technical Instructions on the Transport of Dangerous Goods by Air (ICAO Technical Instructions). PHMSA is considering whether to harmonize with these requirements and is publishing this notice to allow interested persons an opportunity to supplement comments to our January 11, 2010, Notice of Proposed Rulemaking (NPRM).
