The purpose of a Gap Seal is to create a pressure barrier
between the high pressure air on the bottom of the wing
and the low pressure air on the top of the wing. The air moves upward through the gaps, thus causing significant drag and reduced control authority. The Gap Seal smoothes the air
traveling along the bottom of the wing, improving airflow.
The effects of a good Gap Seal kit will be:
4 mph increased cruise speed and 50-100 fpm improved rate
of climb.

This Flap Gap Seal Kit is unlike any other ever offered for Cessna
Aircraft. The revolutionary new installation makes them easy
to install, and they remove in minutes and get out of your way
for inspections, annuals, and service to the flaps. They are the
only seal on the market that fills the entire gap, making them
as aerodynamic as possible adding 4 mph in cruise speed. 
They are made of 2024T-3 Alclad Aluminum for superior
strength, and laser cut for a perfect fit. The Kit comes complete
with all stainless steel hardware, easy to follow step-by-step
instructions, and the Supplemental Type Certificate.
