 I just finished a new presentation on inspecting aircraft hose. Would like any suggestions or comments for improvement.

I don't know about anyone else but your presentation doesn't materialize when I open your link! [and I've tried a 1/2 dozen times]

Bob, Check your browser's security settings - such as allowing popups. If not here is the direct link to the presentation on my blog.

There's also a special application of the "TWISTED STRIPE" I didn't see this in your presentation. The stripe is inspected for proper installation after torque as been applied to both ends of the hose. The stripe runs down the center line of the hose, curvature of the stripe is important otherwise twisted ends will tend to work against the fitting and weaken up in the swagged end collar or end fitting depending on the type of installation. Make sure the line does not twist along its curvature after installation.

That ought to do it!

Good presentation John! My only comment is about slide #9. We, as aircraft maintenance technicians, do not have the authority to "ground" an aicrfaft. I'd suggest verbiage like "do not return the aircraft to service until..." Big difference!

Bob,

Compromise. I placed "ground" in quotes. I'm not sure "return to service" is correct either - this inspection can take place under any countries regulations or even by a pilot during a preflight; so to stay away from legal verbiage, I use the word "grounded' in its common vernacular.

This introduces a whole other topic; what do you do when you see something un-airworthy?

Compromise is good John! You are correct, this action may be performed by a pilot. However, I would suggest that your article's title "Inspecting Aircraft Hose" would imply that this is more likely a maintenance action. My contention is further supported by the www.mechanicsupport.com under your name and the fact you've posted it in a maintenance forum! Nevertheless, it's your article.

I would also submit that using the term "grounded" in its "common vernacular" as you say propagates the misconception that "grounding" an aircraft [by anyone other than the FAA] is possible and we all know that it's not! You employ a professional approach to educate us on hoses, why not continue the education with the proper terminology?

To answer your question on a whole other topic, what do you do when you see something unairworthy? The correct answer is report it to the owner/operator of the aircraft! Why? Because the owner/operator ultimately determines the airworthiness of an aircraft [FAR 91.3 Responsibility and Authority of the pilot in command] no one else.

Respectfully,

Bob,

Seems like I got shot down on that one also.

You are right my friend, I will stick to determining condition and leave what to do about it up to the person in charge.

Works for me!
