Technical Information for the assistance of Members
This information is provided as a guideline to assist members.

EAA always operates within SACAA regulations.
During COVID-19 lockdown, members have been restricted to their homes and aircraft maintenance and upkeep of aircraft has been a major concern to all aircraft owners. The following points and attached documents are a recommended guideline for the maintenance of aircraft under the current lockdown circumstances ;
- Environmental conditions are a big factor in determining preventative action against corrosion.
- Both Continental and Lycoming advise against ground running engines for perceived corrosion relief.. this exacerbates the situation exponentially.
- Flights should be for a period of an hour recommended by Lycoming and Continental, in order for the oil to “boil” off moisture that may have accumulated within the engine.
- Don’t turn the prop once engine is placed in storage.
- If cylinders are to be “fogged” with inhibitor make sure it coats the entire internal surface, squirting an oil can through the plug hole will not suffice.
- Plug openings to the atmosphere (exhaust and breathers especially) with a desiccant to prevent moisture ingress. Don’t forget the red streamers to remove before flight!
- If there is any doubt as to whether there may be corrosion, do not turn the engine and have a borescope inspection done first.
- There is much info on the subject and direction should be taken from the manufacturers bulletins pertaining to the particular engine.
