As a practical matter has anyone seen a 337 for a tow hook installation
on a motor glider, or a U.S. registered motor glider with a tow hook
(on the aft end)?


Diamond Katana Xtreme HK36T

from dealer data sheet
tricycle 27:1 or tailwheel 28:1 l/d
mt 1200lb - maxgross 1698lb (Canadian certification, FAA cert 1750?)
span 54'6"
Rotax 914F turbo 115hp - prop hydraulic cs full feathering
factory optional towing kit $4,152
max tow weight 1,156lb

I would suspect (but cannot confirm) that this aircraft is fully certified
by the factory as an FAA motor glider including the tow configuration. I do
not know how it would be defined by FAA

The next question that occurs to me is whether the unfortunate recent 48?hr
commercial glider pilot in Hawaii would have been legal to give scenics or
to tow gliders or banners (shudder) with this aircraft for pay.
