AD/INST/17 King K1 525 Indicator - Modification 3/2009

Requirement:

CANCELLED.

This AD is cancelled on 12 March 2009.

Background:

This unique Australian AD raised in 1975 against King Service Bulletin (SB)
K1 525-1 required a modification to King K1 525 indicators to modification status Mod.1.

Compliance was before 30 September 1975.

As King had an exchange system in place at the time this AD was raised, and affected King K1 525 Indicators would have been modified by now, this AD is considered to be no longer required.

Delegate of the Civil Aviation Safety Authority
