I've filled all the grid except 1 square, and all makes perfect sense, but can't figure out 14 dn - is the second letter A or I?

Can someone put me out of my misery, please?

[Flyhalf]

What's the clue, and how many letters?

[Neveracrossword]

I finished this, but no longer have the paper. If you give the clue, or the letters you have, I might remember it.

[Jellytussle]

Clue is 'Planes pine boards without energy' A letter in the definition needs changing to 'T'. Answer is D?LS

[slaney]

Pine boards = d(e)als, so DALS =plants

Thanks Slaney.
