Engine Preservation for Active and Stored Aircraft
Supersedes Service Letter No. L180 A
To all Owners and Operators of Textron Lycoming Aircraft Engines
Engines in aircraft that are flown only occasionally may not achieve normal service life because of corrosion. This occurs when moisture from the air and products of combustion combine to attack cylinder walls and bearing surfaces during periods when the aircraft is not used. The procedures for combating this condition consist of coating the vulnerable surfaces with rust inhibitive compounds as herein described.
