GENERAL This Airplane Flight Manual Supplement is applicable to those Cessna 172 airplanes equipped with Aerocet Model 2200 Seaplane Floats. SECTION 2. NORMAL PROCEDURES: (NOTE: these items supplement the basic flight manual and seaplane supplement normal procedures- be sure to follow those procedures except as noted below) BEFORE ENTERING FLOATPLANE 1. Inspect the floats and attachment for dents, cracks, or punctures. Inspect hardware, water rudder and rigging for security. 2. Remove rubber plugs (which serve as stoppers on the standpipe in each float compartment) and pump out any accumulation of water. Reinstall rubber stoppers with enough pressure for a snug fit. (If there is an excess of water, investigate the leakage) 3. Inspect locker door latches – DETENTS ENGAGED, LATCHES TURNED CLOCKWISE TO STOPS. 4. If a canoe or kayaks are installed, verify that all 4 ropes are tied with appropriate knots per the ICA (bowline, two half hitches, and cleat knot,) and that each rope is snug. Verify the forward end of the canoe is 25” max ahead of the firewall. Verify the stern of the canoe or kayak is mounted forward. CAUTION: An un-latched locker bay door will cause a howl and may bang against the float struts during flight. Aircraft should be returned to field in normal fashion to avoid potential damage, and to assess any possible problems. However, as with any situation, “FLY THE AIRCRAFT!” rather than make a rash decision. It is likely that little or no damage will occur to locker door.

FW-JWA658-11 Airplane Flight Manual Supplement for Aerocet Model 2200 Seaplane Float Installation on Cessna Model 172 PAGE 5 FAA Approved: 5/5/2021 Revision: C SECTION 3. EMERGENCY PROCEDURES: Emergency procedures in the FAA approved airplane placards, Pilots Operating Handbook and/or Floatplane Supplement generally apply except for the specific items listed herein. EMERGENCY LANDINGS ON WATER should be done with water rudders up, aircraft slightly tail low on touchdown, and control wheel held full aft as the floatplane decelerates on the water. EMERGENCY LANDINGS ON LAND should be done with water rudders up, aircraft in a level attitude on touchdown, and the control wheel full aft after contact. If damage occurs to the floats causing compartments to flood, aggressively shift the weight (people & baggage) in the opposite direction of damage in order to balance the aircraft over the buoyant compartments. SECTION 4. LIMITATIONS Maximum Weights: Models 172A, 172B: 2220 lbs. Model 172C: 2250 lbs. Models 172D to 172N and F172D to F172N: 2300 lbs. Model 172P and F172P: 2400 lbs.
