| Subject: | 582 Preventive maintenance - stuff that fails |
Last fall I had one side of the ignition system quit on the 582. One of the red
trigger coil wires had broken at the male connector where it plugged into the
coil pack female connector. As good as the Austrians seem to be at building machinery,
they are at least that bad at wiring. They use wire that eventually
goes soft and gummy. In this case, the insulation had gone bad and allowed moisture
to get in, corrode the wire, and it broke.
Three years ago one of the wires from the coil pack had gone mushy on its insulation,
the internal wire corroded, had to have it replaced.
So I pulled the engine, sat it on the workbench so I could poke around inside the
mag end, turned out that both the red wires from both trigger coils had gone
mushy on their external insulation. Imminent failure mode. Clipped them off
close to the coils, used an Exacto knife to scrape off any corrosion, soldered
new wires on, potted the whole mess with much silicone and put it back together.
Also one of the yellow with black stripe wires from the coil packs to ground had
a similar problem, the insulation had turned to mush. Replaced that also. Spent
the afternoon today putting everything back together on the airplane, replaced
all the fuel line as well. Even the good black rubber stuff from NAPA is
cheap enough to replace every 5 years. Peace of mind.
Finally got it done and ran it up just before dark, ran nice and smooth, put it
away. Just now went out to see if the coolant had sucked itself back into the
radiator system, and discovered one of the radiator hoses has moisture around
the lower hose clamp. Tomorrow after church guess I will drain the coolant again,
and replace that hose.
Details, details, details. When you get them all right, then next years flying
season ought to have a lot less drama!
