INSPECTION
A TSO-C91 ELT can be activated by using a quick rap with the palm. A TSO-C91a
ELT can be activated by using a rapid forward (throwing) motion coupled by a rapid
reversing action.
INSPECTION
Verify that the ELT is activated using a wattmeter, the airplane's VHF radio
communications receiver tuned to 121.5 MHz, or other means.
INSPECTION
Reinstall the ELT into its mount and verify the proper direction for crash activation.
Reconnect all cables. They should have some slack at each end and should be
properly secured to the airplane structure for support and protection.
INSPECTION
(4) The presence of a sufficient signal radiated from its antenna Activate the ELT
using the "on" or ELT "test" switch. A low-quality amplitude modulation (AM)
broadcast radio receiver should be used to determine if energy is being transmitted
from the antenna. (continue)
INSPECTION
When the antenna of the AM broadcast radio receiver (tuning dial on any setting) is
held about 6 inches from the activated ELT antenna, the ELT aural tone will be heard.
INSPECTION
Verify that all switches are properly labeled and positioned.
