An aircraft crash locator apparatus mounted on the tail of an aircraft in a round sealed case held by a shear pin which releases under crash impact of 7 to 8 G's is described. The transmitter is powered by a battery which is kept charged by a trickle charge from the navigational light on the tail. The battery has a button actuated meter to test the battery condition while the apparatus is installed on the aircraft. At the time of the crash, the transmitter is released and ejected, the yoyo antenna wound around the case unwinds, and the transmitter starts emitting on emergency frequencies 121.5 unwinds, and the transmitter starts emitting on emergency frequencies 121.5 MHz and 243 MHz. The transmitter, which is shock mounted in a double plastic case, lands and continues transmitting for about 48 hours.
