ASA has released the sixth edition of The Complete Private Pilot Syllabus, a comprehensive guide that include both flight and ground training so pilots learn the skills they need to pass their checkrides.
Stage Exams, Enrollment certificate, Graduation certificate, and Private Pilot application (FAA Form 8710) are all included.
This edition has been updated to reflect the most recent Private Pilot Airman Certification Standards and supports The Complete Private Pilot textbook by Bob Gardner, as well as the Student Pilot Kit and the Complete Private Pilot Kit from ASA.
The softcover, 128-page book is $12.95, while the PDF version of the book is free.

For the free PDF copy click on the red highlight title at beginning of the this article. It takes you to the ASA website for the publication. In the box by the “which format is best for me” change it to read PDF. The fee changes to $0.00. Add it to your cart and go to check out. When finished your final completed order form will have a direct link to download the PDF.
I find no download location for the free PDF of the Complete Private Pilot. I went from a book to PDF and no location on my iPhone allows the download.
