Great memories: adventures with Whiskyblue, my Cessna 170B.

When I first became interested in backcountry flying and started watching YouTube videos, I was mesmerized by a strip deep down in a canyon in Utah's Red Rock Country: Mexican Mountain.
Would I be able to land there?

Leaving the mountains, visiting an old (soaring) playground and from there heading east-south-east.

Great memories: adventures with Whiskyblue, my Cessna 170B.

On my way east from the Rocky Mountains, I ended up in the Ozarks.
The topography was different, of course, as were the colors, but the impressions and emotions that hit me in some places were just as intense.

The saga of Whiskyblue and me.

It started 7 years ago and it might end soon.

These pics are clearly not “in sequence”… as the Lycoming conversion would not be served by the exhaust system in this pic.

I think I made a comment earlier on your posts but I have to say again I really appreciate your stories and YouTubes. The thought processes and having an open mind is inspiring for people like us in our 70s whose choices may sometimes be narrowing. In your case they seem to expand! Hope you stay safe and look forward to hearing about your next adventure.

George, good catch, but you're even more Germanic than I am when it comes to applying conventions and rules...LOL

You must be talking about all pics in this thread, because there's only one in this post, and that was meant to define the context of: " It started seven years ago..."

Thank you for your kind words!

In my last video I mentioned an Airworthiness Directive to be complied with after a prop strike.
I made a quip about it, was it a bit hyperbolic?

As we know, ADs are based on hazards that can adversely affect safety of flight and usually originate from incidents or accidents where a specific problem is identified. Corrective action is then determined followed by a legal process (proposals, public comments) the result of which is mandatory action. Alternative means of compliance are possible. ADs have the same effect as a regulation. But, ADs are not intended to be “gotcha” traps.

In the case of tall grass or any organic material that could get tangled in a propeller, these materials are capable of causing a sudden change in rpm the result of which “might” compromise the integrity of the crankshaft. I believe that is the intent of the paragraph in the AD describing contact not resulting in observed physical damage. It describes a situation where noticeable affect on engine rpm occurs, thus creating the potential for internal damage presumably observed on a similar prior incident that resulted in a safety problem and the subsequent AD.

The reporting of such an incident is the responsibility of the pilot/operator. There is room for judgment in deciding whether or not the contact is serious enough to warrant further investigation or possible action under the AD. If, as you describe, the propeller simply brushes up against loose grass and no change in rpm is noted, I don’t think the AD applies. A pilot who operates in that environment should be careful and avoid that type of contact with a propeller. But said pilot also has the ability and responsibility to determine that a minor brush with grass does not raise to the level described in this AD. In any event, careful attention is called for. I believe this is the best way for a pilot to address the application of this issue.

My weekly dose of aviation.

Welcome back!



Opening the hangar door, looking at my bird and imagining the next trip always creates a warm, fuzzy feeling - even though the coming adventure will be our last one.
