CORROSION PREVENTION
The information supplied here is as a general guideline only, and is by no means intended to be
exhaustive, complete or authoritative. For more in depth information refer to an applicable and
authoritative publication, such as the FAA Advisory Circular AC43.13-1B: Acceptable Methods,
Techniques and Practices - Aircraft Inspection and Repair.
It is highly advisable that expert advice be sought with regard to corrosion related issues.
6061-T6 Aluminium (of which the aircraft is constructed) is reasonably corrosion resistant and
accordingly is unlikely to corrode substantially.
It is important to keep the aircraft clean and to remove any collection of corrosive causing agents
such as water, anti-freeze, oil, grease, dregs and other foreign matter. To avoid damage to the
finish, do not use polishing detergents. Original or equivalent corrosion prevention, if used, must be
re-applied after any alteration or repair. If any trace of corrosion is detected it should be removed as
soon as possible and the applicable part should be treated immediately to prevent further corrosion.
Treatment consists of mechanically removing as much as possible of any corrosion by-products,
applying corrosion inhibitor and replacing any original finish.
STRUCTURES
STEEL PARTS:
With the exception of highly stressed components or stainless steel, it is possible to use
abrasives, steel brushes (if operated manually) and steel wool
.
ALUMINIUM PARTS
:
Steel wool, emery cloth or steel wire brushes (unless stainless steel), copper alloy brushes,
rotary wire brushes along with other highly abrasive material should not be used. Steel or
emery particles become embedded in the softer material causing corrosion.
Accurate brushing with a sturdy fibre brush should get rid most of the corrosion and ensures
that the anti-corrosion agent penetrates completely into the cracks.
