Rotax 912 Aircraft Engine Storage during Covid-19 Pandemic and How to Properly Store your Engine
Aircraft and components (including engines), which are not flown often, may require additional maintenance. These may be subject to damage from corrosion and contamination, which may adversely affect their safe operation and service life. Some manufacturers publish guidance as to how best protect these aircraft, engines and components.
Failure to store the aircraft/components in accordance with manufacturers’ guidelines may affect the safe operation of the aircraft/engine and warranty claims. Manufacturers’ recommendations should be followed when returning an aircraft to service following storage. Failure to properly store or ‘return to service’ an aircraft/component may result in an aircraft accident/incident.
The need for an aircraft storage programmer must be evaluated by the owner/operator. It is important to consider the recommendations of the manufacturers, the environmental conditions and frequency of aircraft activity. For certain aircraft manufacturers, aircraft which remain inactive for 30 days, or more, require a storage programmer. While some manufacturers recommend, in coastal areas, that the aircraft should be flown at least once a week for a minimum of one hour to remain active. Initiating an effective storage programmer shall minimize the risks to your aircraft, components and engine(s).
Owners/Operators are encouraged to familiarize themselves with the recommendations published by the aircraft, component and engine manufacturers with regards to storage.
Typically, aircraft storage involves covering all openings which may allow moisture/dirt ingress, securing the aircraft and protecting the components. If the airplane is to be stored outside, the pitot tubes, static vents, air vent openings in the engine cowl, and other openings may require protective covers to prevent entry of foreign objects including dirt, insects and birds. Component manufacturers may also issue recommendations regarding the safe storage of the component e.g. GPS units, avionics boxes and tyres.
Getting the 912 ready for periods of storage - there are two ways of doing this. The first is with a fuel stabilizer. The second is by draining the fuel system.
