NOTE A. Each aircraft manufactured subsequent to 6/?1/44, must, prior to
original certification, satisfactorily pass:
(a) An inspection for workmanship, materials and conformity during
construction.
(b) A final inspection of the completed aircraft.
(c) Check of flight characteristics.
Weight and balance report including list of equipment included in
certificated weight empty, and loading instructions when necessary, must
be submitted for each aircraft with original inspector's report and each
subsequent report covering change in effective
If provisions other than Item 102 are made for dumping, the fuel
dump valves shall be made positively inoperative.
If Item 102 is installed, the aircraft operation record shall
incorporate one of the following statements,
Non-Air Carrier. "Fuel shall not be dumped except in accordance
the provision of CAR 60.900."
With authorized weight in excess of maximum landing
weight - Landing shall not be made at a weight in excess
of maximum landing weight except in accordance with CAR
Fuel shall not be dumped except in accordance with
CAR 61.7811 and then only if the pilot deems it safer than
landing at a weight in excess of maximum landing
With authorized weight not in excess of maximum landing
weight - "Fuel shall not be dumped except in accordance

To look rudders and elevator:
Elevators must be fully down.
(2) Rudders must be moved to neutral.
(3) Raise look lever and engage socket.
It should be noted that the forward C.G. limits shown for "landing"
determine the most forward C.G. locations at which the airplane complies
with the landing requirements of the Civil Air Regulations.
"flight" limits may be used only under special conditions since the
airplane must never be flown with its load arranged in such a manner
that the approved forward "landing" limit cannot be realized readily by
shifting passengers and available crew members in case an emergency
In order to utilize the wide "flight" c.G. limits, it is necessary that
the loading instruction referred to in NOTE 1 be prepared in such a manner
that they satisfactorily provide for the following restrictions:
Whenever the airplane C.G. is located ahead of the approved forward
landing limit, a sufficient number of passengers and/or crew members
must be available to be shifted in such a manner as a move the C.G.
within the approved "landing" limits.
At no time may the airplane C.G. be permitted to move outside the
"flight" limits.
NOTE 8. When Item 101 is installed, continuous operation between 1750 and
2050 engine rpm should be avoided.
NOTE 9- When Item 203 is installed (Model 314), the placard "Take-off" limit
must be reduced to 42 in. Hg.. 2300 rpm (1500 bp).
