AD/RAD/34 Sunair HF Transceiver - Modification 4/2009

Requirement:

CANCELLED.

This AD is cancelled on 9 April 2009.

Background:

This unique Australian AD was raised in1976 against Sunair Service Bulletin (SB) No. 320-001, dated 2 November 1978, requiring a modification to Sunair HF Transceiver ASB -320( ) due insufficient protection against high short circuit currents.

Compliance was before 31 January 1978.

Given the extended period this AD has been promulgated, and that affected HF Transceiver would have been modified by now, this AD is considered to be no longer required.
