Robertson STOL - positive flap retraction

[Timothy Urban]

The Robertson STOL system for PA-30s is limited to 15 degrees flaps unless a subsequent positive flap retraction system was installed. Am looking for the Robertson Service Bulletin #19, and advice as to how you can look at the plane and tell if the positive flap system is installed in your plane (other than absence of a placard on your flap switch).

Thx in advance for any PDFs, photos, etc.

FYI for the next guy searching this topic, the Robertson service letter #19 is available through Lancair in Uvalde, TX. More positive flap retraction system kits may be built sometime in 2018 but no new ones are available at this time.

Hey guys, on the Robertson STOL topic. Would anyone here happen to have the flight manual supplement available, recently purchased PA-30 seems to be missing it. I've contacted the current STC holder with no help as of yet,thanks
