PS MAGAZINE 
PREVENTATIVE MAINTENANCE ON UH-1s

PS, The Preventive Maintenance Monthly is series of United States Army technical bulletins published since June 1951 as a monthly magazine with comic book-style art to illustrate proper preventive maintenance methods. The magazine's title derives from its being a "postscript" to technical manuals and other published maintenance guidance.  Thank you to Peter and Wendy who went through the archives and pulled UH-1 related PS pages to put on the site
