Prop "Strike"?

Parked in grass at fly-in. Leaving, started up, began to taxi, prop struck taxi light. One blade apparently struck nearest edge of housing near top where light lens is seated, causing the whole light stick to fall flat away from prop. I know nothing should be considered trivial when prop hits anything, but... From what I've read, and I am aware of the Lycoming circular on strikes, it is possible to have a "trivial" incident. Didn't have sudden decrease in rpm or stop in one revolution. Nothing bent. Just one area the size of my little finger nail or smaller where paint is off. It "grazed" the light enough to knock it down, but still does appear trivial to me. The Lycoming document mentions strikes as incidents involving prop repair "other than minor dressing of the prop". That surely includes paint. Of course my mechanic will look at this. If he agrees nothing more than "minor dressing" is needed (or nothing), will he still need to write something up for the log? Thanks! Feeling very disappointed and embarrassed... But Thankful - Sure could've been worse!
 
So what are you looking for? Someone here to tell you it's okay? :dunno:

Sorry, didn't mean to be harsh but really there isn't anything anyone here can say or do to help you with this.
 
A log entry on a prop strike and inspection? Would a new owner care?
 
If you don't log it as a prop strike ,your not being honest or fair to the next owner.
 
A paint chip the size of a fingernail? I'm not sure you actually had a prop strike.

If you log it as a prop strike and don't do a tear-down inspection, I suspect a lot of potential buyers will walk.

I agree with Silvaire: this is really a matter to discuss with his A&P.

I am not familiar with Lycs (all engines I own are Continentals). If it was a Continental, what you are describing probably would not fit the description of a prop strike that requires tear down.
 
You've probably read Lycoming SB 533B. According to your description and the SB, there was no prop strike, no repair needed and nothing to log.
 
In all honesty I'm thinking a runway light is but then I wasn't there :dunno:

Read the service bulletin. But short story... If you don't need to remove the prop from the airplane to repair, it's not a prop strike.

When you return from a flight, and find a pretty good ding in the prop. Then your A&P tells you it is too deep to blend, and must go to the prop shop for repair. Is that a prop strike? Does the Lycoming AD apply?

I think that is a quiz-type question but it's a valid one.

All props get little dings. They have obviously "struck" something like a pebble. How large does the ding need to be before it is considered a "prop strike"?
 
If there was no decrease in RPMs, them IMHO it isn't a strike.

But you wont believe how expensive fixing an edge light can be.
 
There are specific Lycoming and Continental guidelines for defining the circumstances identifying a "prop striker" as seen by the manufacturer. Another consideration is your insurance company. Many feel the cost of a prop-strike inspection repair is significantly less than any subsequent incident which might be a responsibility in down-stream court contest.

I recommend looking into this aspect as well.
 
How many readers made the assumption this was an aluminum propeller?

He said there was paint chipped. Haven't seen any painted wood props. Do they paint composites?

They paint both. Many Spitfires had wood props. They were painted black.

My current composite prop is painted light grey.

Doesn't the prop manufacturer's repair limits and procedures have any effect on you making the decision to repair or replace the propeller?

When folks say " Prop strike " they automatically think Engine, when it is just as important to consider the Prop manufacturer's limits, and repair procedures.
 
To legally fly this aircraft away from the fly in wouldn't the determination of prop strike or not need to be made before departing? Obviously not an issue if the pilot did not know about the contact with the light until informed upon arrival at the home base airport where the aircraft has remained on the ground since.

Yep...Yep,,,,,, I get it. ask a question see who knows and who don't, someone might learn something that may help the nube in the future. But here, the ones that know it all, will accuse you of trolling.

Perhaps it's because of the way people who answer "incorrectly" are treated? :dunno:

Are you actually implying that you are the all-knowing expert?

Have you ever seen me accusing me of trolling? Only those who believe they know every thing will accuse those who ask questions of trolling.

There are a lot of different kinds of trolling, and I do think some of your questions are intended to stir up arguments. That to me is trolling.
 
You took the light out and only scratched the paint?

Have your AP take a look at it, how you word it is up to you, if it turns out to be nothing you couldmalwaysnwrite something like "touched up prop paint blah blah blah"

If trolling is the cause of some one learning, you should be good with it.
