What are Safety Bulletins?
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.
Aeroprakt approach to safety bulletins
Aeroprakt is particularly good at 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 acknowledging a problem.
Aeroprakt always have at least two aircraft in continual use at their own Aeroprakt club airfield. Very often these aircraft have completed many more flying hours and landings, with a wide variety of different pilots, than the average 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 Aeroprakt issues a safety bulletin, all subsequent aircraft are manufactured incorporating the mandated (or sometimes recommended) change(s) required by the bulletin.
Bulletins are usually categorised into:
- Mandatory, 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 may fundamentally affect the safety of the aircraft and its occupants;
- Advisory, 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, it is the owner's choice whether to action the safety 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.
Not all bulletins apply to all aircraft. It is the owner's responsibility to check their own aircraft serial number (NB - not the registration!) to decide whether a particular change is required to their own aircraft or component.
