Compass Correction Card

Just for fun......

A long time ago, I was told that a compass correction card is
required.
I was also told it didn't have to be filled out.
That may not be a good idea.
No need to upset our FAA friends.

I believe AC 43.13B can give you a little guidance on that matter.



AC 43.13-1B lists several instances when a compass swing must be
performed. These include:
Whenever the accuracy of the compass is suspected

After a cockpit modification or major replacement involving ferrous
metal

Whenever a compass has been subjected to a shock; for example, after a
hard landing or turbulence

After aircraft has passed through a severe electrical storm

After a lightning strike

Whenever a change is made to the electrical system

Whenever a change of cargo is likely to affect the compass

After an aircraft has been parked on one heading for more than a year

When flux valves are replaced.



An often overlooked matter amongst us aviation technicians.

If compass is perfect, I've been told by my IA, no correction card is
required.
Find a fed that will buy that!

Prolly' wouldn't. Just put all zeros on a correction card.

I think you are all missing the point.

If no compass is required there cannot be a requirement for a
correction card.

In the world of Federal Aviation Regulations the compass is called a
"magnetic direction indicator" and the compass correction card is a
"placard". Try a search of all the regulations (www.landings.com) and
try to find one regulation related to the installation of a magnetic
direction indicator in a "glider" or an "aircraft" - I found none!
All the regulatory requirements are specific to airplanes, rotorcraft,
or certain airships.

Anyone who finds one related to gliders please let me know. Otherwise
celebrate your freedom by burning your correction cards.

At least for my LS8-18, the feds can get you another way - a compass
is on the Minimum Equipment List. So my glider is required to have a
"magnetic direction indicator". The jury is still out on a correction
card, though...

Wouldn't be too sure about that. I believe a non-required instrument
which is not functioning properly (which might well include an
uncorrected compass) must be covered up or removed. A power club I
once belonged to ran into that, being forced to remove a failed DG
from a VFR-only airplane.
