Engine baffles should be cleaned with a suitable solvent (Mineral Turpentine) to remove dirt and
oil.
Inspect baffles for cracks, splits or damage. In particular, ensure that the hard-points where the
ducts are bolted to the engine are in good condition.

Return to Service:
Rubber seals may be replaced by removing the existing rubber parts, rubbing back the bonding
face of the fibreglass baffles to bare glass (using 80 grit sandpaper or similar) and bonding new
rubber strips in place with 5-Minute Araldite.
Damaged mounting hard points for the air ducts are best repaired by the installation of reinforcing
tags as shown in Figure 146.
7.4.5 Cooling Air Baffle Installation
Reverse the preceding steps for installation.
An improperly secured air duct may result in poor cooling, high engine temperatures and engine
damage. In addition, cases have been recorded where a poorly fitted duct lifted from the engine
and pulled the spark plug leads off the engine, resulting in engine stoppage.
This document is controlled while it remains on the Jabiru server. Once this no longer applies the document becomes uncontrolled.
