OT Safety Bulletin

Propeller hazard

An old hazard that is still around in aviation today are propellers. New people to aviation should always be made aware through training never to enter the arc of a propeller and get into the habit of always avoiding them.

Dealing with failure

ATS systems have multiple layers of protection to ensure that power is always available. Transfer from mains to generator or battery power is normally seamless using Uninterrupted Power Supplies connected to critical equipment. However, experience has shown that sometimes both the primary and secondary means of power can both fail leaving the ATS systems just running on battery power.

Runaway Trim

Reviewing some recent General Aviation reports highlighted that in some cases pilots need to be ready to recognise and act promptly in the event of a runaway trim. Some aircraft types require a quick response to prevent a loss of control. Therefore, if you are not sure what your aircraft’s pilot operation handbook/ flight manual says about this go and refresh your memory. Understand the system, and what to do if it goes wrong.

Defuelling

The Aeronautical Information Publication (AIP) is the place to go for information on an aerodrome. Within it you can find out all sorts of information to ensure an aircraft’s safe passage through. One important section when trip planning is fuel.

Prevention of Runway Incursions During Emergency Response

Preventing runway incursions is a core element of runway safety programmes. The aim of the safety programme is to reduce hazards and manage risk. Managing risk requires a systematic approach involving all stakeholders. For the programme to be effective it requires appropriate input and promotion from senior management which reinforces their commitment to runway safety.

Safety Awareness – Independent Inspections

Independent inspections are an important part of airworthiness and are a requirement. However, there are common errors that lead to these being ineffective.
