Proposed Technical Standard Order (TSO)-C126b, 406 MHz Emergency Locator Transmitters (ELT) and Notice of Intent To Withdraw TSO Authorizations (TSOA) for TSO-C91a, Emergency Locator Transmitter (ELT) Equipment, and TSO-C126/C126a, 406 MHz Emergency Locator Transmitters (ELT)
This notice announces the availability of proposed TSO-C126b and the FAA's intent to withdraw TSO authorizations (TSOA) issued for the manufacture of automatic fixed (AF) and automatic portable (AP) ELTs under TSO-C91a, TSO-C126, and TSO-C126a which incorporate hook and loop fasteners in their design. This proposed action would affect ELT manufacturers. The FAA is not proposing requiring actions on previously installed ELTs. The FAA is taking this action based on its determination that hook and loop fasteners are not an acceptable means of compliance to meet the mounting and retention requirements of current TSOs for ELTs. The FAA is requesting comment on proposed TSO- C126b and the FAA's proposal to withdraw certain other ELT TSOAs.
Modification of Class E Airspace; Plentywood, MT
This action modifies Class E airspace at Plentywood Sher-Wood Airport, Plentywood, MT. Controlled airspace is necessary to accommodate aircraft using Area Navigation (RNAV) Global Positioning System (GPS) standard instrument approach procedures at Plentywood Sher-Wood Airport. This improves the safety and management of Instrument Flight Rules (IFR) operations at the airport. This action also makes a minor adjustment to the geographic coordinates of the airport.
