Radio Communication and Navigation Equipment

AD/RAD/29 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. 100A-001, dated 15 April 1974, requiring a modification to Sunair HF Transceiver ASB -100 and -100A due possible smoke/fire hazard would exit if a short of primary wires occurred carrying power to the receiver/exciter, or the antenna tuning unit.

Compliance was before 31 March 1977.

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.
