Does the FAA have written policy WRT landouts?

A student landed out just short of our airport in our club's 1-26 last
Saturday. No damage, no injuries, glider readily returned to it's
tiedown.

Apparently, the airport manager told his bosses about it and they
chewed him out for not immediately reporting the landout to NTSB.

The story goes on longer but I'll spare the details and cut-to-the-
chase. Does the FAA have any written policy/advisory circulars on
landouts that don't involve damage or injury and whether or not
they're reportable to NTSB? (Presumably, they're not reportable). All
this must have been played out many times before at public airports
where there is gliding.

I'm really after written documentation of FAA policy, not opinion or
haranguing. Some of our club members appear to have tried the latter
with the net result of creating hard feelings.

Thanks,
Larry
