Inspecting The Magnetic Plug - Rotax 914 Series Maintenance Manual

5.4)

Inspecting the magnetic plug

See Fig. 38.
Remove the magnetic plug and inspect it for accumulation of chips.
◆ NOTE
This inspection is important because it allows conclusions to be drawn on the
internal condition of the gearbox and engine and reveals information about
possible damage.
If a significant amount of metal chips is detected, the engine must be inspected,
repaired or overhauled.
Steel chips in low numbers as depicted in Fig. 38 can be tolerated if the
accumulation is below 3 mm (0.125 in).
In the case of unclear findings, flush the oil circuit and fit a new oil filter.
Afterwards conduct engine test run and inspect the oil filter once more.
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.
- Inspect all systems for correct function.
- Detailed inspection of affected engine components.
■ CAUTION:
Trace the cause and remedy.
Clean the magnetic plug and refit it. Tightening torque 25 Nm (18.5 ft.lb). Safety-
