weight and balance report  including list of equipment included in
certificated weight empty, and loading  instructions when necessary,
be submitted for each aircraft with original inspector's report and each
subsequent report covering changes in equipment.
NOTE 2.  The following placard must be conspicuously posted at the righ
rear main fuel tank (wing) filler cap:  •FILL WITH 87 OCTANE  FUEL ONLY.
when Item 38 is installed, in lieu of above, a placard must be conspicuously

(T)  with authorized weight in excess of landing weight - 'Landing

shall not be made at a weight in excess of maximum landing weight
except in accordance with CAR 61.7811.  Fuel shall not be dumpe
xcept in accordance with CAR 61.7811 and then only if the pilo
deems it safer than landing at a weight in excess of maximum
