Ignition coils replacement

Jabiru recently recalled a batch of defective ignition coils, to be replaced under warranty.
Here is the letter received by the British owners from their dealers.

Ignition Coils - Glossy Black Coils marked "LEADING GX"

We have been monitoring a problem with ignition coils fitted to recent Jabiru engines, we have seen tell tail signs of break down leading to either a misfire, failure or call to ourselves for advice. The tell tale signs are: hard to start, ignition noise on RT, missing at high load typically in the climb or eventually complete failure at Mag Check.

The original GREY coils P/N P10522N have never given problems with over 600 coils in service in the UK and only 1-2 failures since 1996.

Our supplier stopped producing this coil and Jabiru sourced another coil P/N P10523N, it can be identified by a gloss black casing and text "LEADING GC'. Some of these coils have been breaking down on high usage aircraft, as well as a couple of moderate usage.

The engines fitted with these coils are:

2200
22A1292 to 22A1528

3300
33A0360 to 33A0536

Grey coils are considered good.

Matt Black coils P/N P10524N with a rectangular projection on the side and marked TEK (looks like TEC) JAPAN FL833 are considered good.
All new engines from S/N 1529 (2200) and 537 (3300) use TEK coils.

Recommended Action

If your engine is within this serial number range or you have a glossy black coil fitted :

  1. Do not fly until replacement coils have been supplied by Jabiru.
  2. Strongly recommend that all cowled installations supply cooling air to the coils
  3. Fit insulating washers P/N PH4A004 under coils to prevent heat transfer
