INSPECTING THE MAGNETIC PLUG
General note
NOTE
The magnetic plug is located on the crankcase between cylinder 2 and gearbox.
This inspection is important because it allows conclusions to be drawn on the internal con-
dition of the gearbox and engine and reveals information about possible damage.
Procedure Remove the magnetic plug and inspect it for accumulation of chips.
Steel chips in low
numbers
Steel chips in low numbers as depicted in Fig. Overview can be tolerated if the accumula-
tion is below 3 mm (0.125 in).
Steel chips in
larger numbers
If there are larger accumulations of metal chips on the magnetic plug, the engine must be
repaired or overhauled in accordance with the BRP-Rotax instructions for continued
airworthiness.
Unclear findings In the case of unclear findings:
Step
Procedure
1

2 Flush the oil circuit.
3
Fit a new oil filter.
4 Install the magnetic plug.
See Chapter 12–20–00 section Installation of the magnetic plug.
5
Engine test run.
