These informative files were written by well-known warbird expert Randy Sohn (former USAF B-25 instructor and DC-3 Captain at North Central Airlines.)
He had graciously given us authority to share them with the round-engine fans.
There are 112 pages of PDF, filled with documentation on how things work with these amazing ’round engine’ aircraft from the past. Technical notes on aircraft parts, machinations, some flying tips and even a chapter on Belly Landings.
From Randy’s Introduction:
“These bulletins were derived from the collective experiences of many people operating and/or maintaining these aircraft during that period during which they’d been the over-riding majority of the industry. More than a few of those aforementioned people have subsequently “gone west” so I’d imagine that this series probably represents the only record of their experiences.
It’s been my intent to make every effort to faithfully record their recollections/experiences, along with those that I’ve encountered during the years we spent with this equipment.
In any endeavor of this type it seems of great importance that any of these recollections /beliefs /opinions tainted by “Old Wives’ Tales (OWT’s) be evaluated, and then sometimes, discarded…”
