Don't have a reference must have been a club reg. Was told it was to do with weight on the flaps during boarding. I've checked an old POH and an online one and the only reference was to ensuring the flap was fully retracted in order to support weight.
Out of interest are there any other clubs with a weight limit for boarding the PA28? It's been a while since I instructed, and I'm quite certain I didn't just pluck this our of thin air!
