Check installed placards against the AFM
or POH, and installation drawings.

Hulls &
Struts

Float Installation

Float exterior - inspect for damage,
wrinkled metal, corrosion, paint
loss, all cover seals, etc.

Boarding steps: disassemble as needed
and grease the step slide tubes.

If the floats are installed, remove
the center section fairings for
access. Struts and attach fittings:
clean upper attach fittings and dog
bone saddle area. If off aircraft, re-
grease bolts and return.

Disassemble and grease the flying wire
clevis bolts/pins and fittings.

Spreader Bars: inspect for loose
screws and cracks & seal between
fairing and side skin. Insp. fairings
for cracking and loose screws.

On the aircraft and floats: re-coat
exposed hardware with suitable
coating for corrosion protection.

Float
Interiors

Float structure (interior): pull up baggage
floors and inspect bulkheads.
Pull up all top deck covers and wheel well
covers to inspect seals.

Closely inspect for wrinkled metal &
cracked flanges; watch closely bulk
heads 9-21.

Baggage compartment covers and seals -
