applicable, of this chapter has been made.
(b) No person may carry any person (other than crewmembers) in an aircraft that has
been maintained, rebuilt, or altered in a manner that may have appreciably

until an appropriately rated pilot with at least a private pilot certificate flies the
aircraft, makes an operational check of the maintenance performed or alteration
made, and logs the flight in the aircraft records.
(c) The aircraft does not have to be flown as required by paragraph (b) of this section

1.
Remove all interconnections to the ELT Main Unit and ELT antenna. Visually
inspect and confirm proper seating of all connector pins. Special attention
should be given to coaxial center conductor pins, which are prone to retracting
into the connector housing.
2. Remove ELT from the mount and inspect the mounting hardware. All required
mounting hardware should be reinstalled and secured.
3. Gain access to the ELT battery and inspect. No corrosion should be detectable.
Verify that the ELT battery is approved and check its expiration date.
4. Activate the ELT using applied force. The direction for mounting and force
activation is indicated on the ELT. A TSO-C91a 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.
Manufacturer’s instructions should be referred to prior to activation. Verify
that the ELT has been activated by use of a Wattmeter, the airplane’s VHFG
Radio Communications Receiver when tuned to 121.5 MHz, or other means.
(See Note 1).
5. 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 be
properly secured to the Airplane structure for support and protection.
