Closing the forward pax door from the top of the aircrafts airstair not a mobile set is not for the feint hearted. The safety rails have to be down to accomplish the task. The door is heavy and although damped can move with speed and energy.
Take note of windspeed (Robin 2 take note!!), I believe their are published wind limits for opening and closing Boeing doors at all entry points.
Beware of the girt bar on the slide this can easily get entangled
in lose clothing resulting in an inadvertant deployment, highly dangerous. It might also force you over the side of the stairs again highly dangerous.
If mobile stairs are on the rear of the aircraft close the forward door from the inside and depart via the rear door. If they are not think about asking for them. That extra 30 yards walk is better than ending up in hospital.
The strap which is placed across the open door is an indicator not a safety strap it will not support your weight.
The integral airstair is safe as long as it is operated carefully.
Most crews are not in practice at closing it from the outside as the normally leave the aircraft to engineering. Next time you have 5 ask the engineers for a demo and to jc 2354 their lives are just as important as yours and your crew!!!!!!!!!!!!!!!!!!!!
