What is the Gull Wing prop?
The prop I saw had the tip bent back maybe 1/4"-3/8".

The Gullwing prop is a nickname given to the prop used on
the 152. The inboard section of its blades were angled forward a few
degrees, then straightened out past that. If it was laid flat on a
table it would look from the side like a gull in flight.
That angle caused structural failures in the blades.
Centrifugal forces tried to straighten that bend and it would crack.
The prop type was a McCauley 1A103, and ADs 95-21-01PL,
97-06-16, and 2003-12-05 applied to it, with the newest ADs supseding
the earlier ones.
