I'm only a low hour PPL with not a lot of experience outside of long, wide, paved runways.
As many pilots are - and short grass strips tend to intimidate to the extent that they are avoided. This is a pity as you will miss so much in your flying career by staying away. However I'll tell you a story...
Many years ago a pilot I knew quite well wanted to go to a grass strip up north. Having only long tarmac experience it daunted him so he wisely took along an instructor for the first trip and again for the second. Go a few months down the line and he'd established a reasonably frequent routine to this airfield.
One glorious June morning he set off again for B***** and rather grandly stuffed the aircraft through the hedge at the end of the runway. Not a mild prang either - wing ripped off (no fire luckily) and some very shaken passengers.
It didn't take long to see where things had started to go wrong. He'd flown there enough to become complacent and didn't see the odds stacking against him. All his earlier flights had been solo but, on this summer trip, he loaded the dice just a little too much:
1. Temperatures were around +21.
2. There wasn't a breath of wind.
3. He had four people on board and a lot of fuel - probably Max AUW minus the 40min fuel for the trip flown.
4. He'd been there enough to think it was no problem.
The scenario was all too obvious to him in hindsight - as it is to most readers here - but he never flew again.
A flight into a short grass strip has to be thought about carefully - not just the first flight but for every subsequent flight. Conditions change enough to make short strips definite go or no go candidates and it is up to the pilot to do the groundwork for every flight to see if they are in his favour.
Never, ever, get complacent on grass.. Keep your head sharp and they can be a lot of fun..
