What are they?
Safety bulletins are issued from time to time when a manufacturer (or local aviation organisation) believes there is sufficient evidence to show some kind of remedial action needs be taken to correct a design or manufacturing deficiency in the aircraft or one of its components. Very often, any deficiency (if it is there at all) appears after many hours in service and the manufacturer usually requires a clear pattern of evidence before issuing a bulletin.
Evektor's approach to safety bulletins
Evektor, with its GA manufacturing background, places particular emphasis on keeping on top of any potential problems and rapidly issuing a bulletin if needed - contrast this with some manufacturers who prefer not to dent sales through announcing problems!
Evektor maintains its own demonstration fleet of aircraft at its base in the Czech Republic. Very often these aircraft have completed many more flying hours and landings, with a wide variety of different pilots, than the average private pilot/owner. Any remedies required are first tested extensively on these aircraft before they are released to the broader base of owners and pilots.
When a safety bulletin is issued
After Evektor issues a safety bulletin, all aircraft are manufactured incorporating the mandated (or sometimes recommended) change(s) required by the bulletin.
Bulletins are usually categorized through one method or another into:
- Mandatory, ie the change must be incorporated, sometimes before the next flight, or sometimes at the next scheduled service. An example of a mandatory bulletin would be one which fundamentally affects the safety of the aircraft and its occupants;
- Advisory, ie the manufacturer recommends the change but does not mandate it. An example of an advisory bulletin might be one where the basic safety is not affected but the change may help improve service life of a component, or minimize the chance of a potential future problem;
- Optional, ie it is the owner's choice whether to action the bulletin or not. An example of this type of bulletin might be the incorporation of an oil thermostat to stabilize engine oil temperatures in certain flying conditions.
Below are listed current safety bulletins relating to Evektor airframes, Rotax engine and propellers used by Evektor aircraft.
Not all bulletins apply to all aircraft, engines, propellers etc - so it is the owner's responsibility to check their own serial numbers to decide whether a particular change is required to their own aircraft or component.
