A wing should be a smooth lifting surface, with no leakage between the high-pressure bottom side and the low pressure upper side.

A Piper’s wing is neither smooth nor free from leaks. Stopping the leakage of air across the wing is easy. All you have to do is put gap seals between the wing and the flaps and between the wing and the ailerons. This is simple and highly cost effective. Sealing these gaps will gain you approximately five to six M.P.H. in cruise speed and fifty feet per minute in rate of climb. You get an added bonus of lower stall speed and much greater aileron effectiveness.

This is a mod you can’t afford to do without- the fuel savings alone will surely pay for the installation itself in no time!

Note: Some of the earliest PA28 aircraft (1961-1965) have outward facing flutes/ribs in the aileron skin instead of the later standard version of inward facing flutes/ribs. If your aircraft has outward flutes the standard Aileron Gap Seals will not fit, but we can build a modified gap seal that has cut-outs where the flutes would make contact. This is an additional $100 charge and we need 5 business days to build them.
