Safety messages are produced by our Safety Investigation Unit when it’s appropriate to provide timely information about a safety matter, even if an investigation is ongoing.

The intention of safety messages is to encourage the swift spread of safety information.

Pin them up on your crew room notice board, or use them as handouts during meetings and briefings, to raise awareness and promote discussion.

You’re encouraged to report occurrences quickly so we can identify possible emerging trends or risks that may benefit other participants.

Safety messages for unmanned aircraft

Information to help you operate Unmanned Aircraft (UA/drones) safely.

The risk of incorrect altimeter settings

In May 2022, an Airbus A320 approaching Paris Charles de Gaulle airport was given an incorrect altimeter pressure setting, which caused the barometric altimeters on board to indicate that the aircraft was nearly 300 feet higher above the ground than it actually was.

Practise and exercise good judgement

The first four months of 2022 saw a significant number of landing accidents. There were 12 recorded as of the end of April.

Double-check your helicopter doors!

An increasing number of reports have been received relating to helicopter doors opening inflight, across a number of helicopter makes and models.

Non-conformance with uncontrolled or unattended aerodrome circuit procedures can be fatal

A recent spate of incidents and accidents, including the loss of life at an uncontrolled aerodrome, has prompted the Civil Aviation Authority to issue this safety message.

Loose items can be fatal

Analysis of helicopter occurrence data has identified a number of accidents and incidents where loose items in the cabin have exited the helicopter and contacted the tail rotor. In some cases this has resulted in a complete loss of control of the helicopter.

Check the carb icing graph

An investigation into a Robinson R22 loss of power accident that revealed no mechanical abnormalities or fuel problems highlighted the potential for the undetected build-up of carburettor icing.

Ensure the power lever friction is set and serviceable

A safety investigation has identified that when a pilot operating a fixed-wing aircraft, in the agricultural role, releases the power lever on take-off to place their hand on the ‘dump’ lever, there is a potential safety risk of the power lever migrating back uncommanded.

Adjust cockpit dimmer controls

Investigations into two commercial helicopter accidents in two years have identified a significant common factor; the annunciator panel lights were not adjusted to a visible level. Crews should ensure when preparing to fly the aircraft; that the dimmer controls are set to suit the operational situation.
