Airworthiness Notice - B026, Edition 2 - 17 October 1995
Emergency Locator Transmitter Rules
(This Airworthiness Notice supersedes AN No. B026, Edition 1)
(dated 17
March 1995.)
Effective
19 December 1994, the Federal Aviation Administration (FAA) has cancelled
TSO-C91, and effective 21 June 1995, the FAA has also mandated that only
TSO-C91a emergency locator transmitters (ELTs) must be installed in a new
installation.
Since
satisfactory performance of TSO-C91 ELTs has been achieved in Canada through
application of the annual inspection, Canada will not require the mandatory
fitment of TSO-C91a ELTs. Both TSO‑C91
and C91a ELTs are eligible for installation in Canadian registered aircraft
provided that Canadian airworthiness approval has been obtained through the
normal airworthiness process (refer to the current edition of AN No. B014 for
ELT installations).
For
issuance of a Certificate of Airworthiness for export to the United States after
21 June 1995, if an ELT is permanently fitted, it must comply to TSO-C91a,
however, an exception is allowed for temporary installations of TSO-C91 ELTs for
the purpose of manufacturing, preparation and delivery flight of aircraft.
