I used the following for the Arrow:
"Welcome on board for your flight in this Piper Arrow.
You will find a seatbelt on either side of your seat, i will be happy to demonstrate it's operation if you are unfamiliar with it's design.
For safety reasons l must ask you to refrain from touching any of the a/c controls and there is no smoking permitted in the a/c at any time during the flight or on the ground.
Also the use of mobile phones or electronic equipment is not allowed. If you have a mobile phone l would ask you to switch it of at this time.
In the event of an emergency requiring a forced landing, you will be requested to adopt the braced position (demonstrate) ensuring your seat back is upright, seat belt is fastened and to remove any false teeth and spectacles.
The door is unlockd by moving the top latch forward and the bottom latch upwards (demo) and then pushing the door outward. If required to evacuate, exit the a/c to the rear and move to a safe point upwind.
In the unlikely event of a fire on board, there is a fire extinguisher between the seats and a first aid kit in the pouch behind your seat (show)
Hope that helps.
