Check your door pins for loosness. During annual all mine were change and what I saw was 50% of the pin was worn away. While helping a friend at the apt today on another 172, he opened the door and it bound up,, I prevented him from forcing it and we found the bottom half of the hinge pin broken jamming the hinge. Don't know if you priced a new hinge but ONE from Cessna is around $800 + labor to install so it is much cheaper to put in new pins than break the hinge.

Check yours and save $$ and pain / agony.

50% of it was worn away, or it was 50% of its original diameer? Big difference there. If it is worn to 50% of its original diameter it means only 25% of the original material is left meaning it is 25% as strong as it was when new.

the pin aat the wear points was 50% the diameter of a new pin. But I didn't do a tension anlaysis to determine the stress strain curve.

Finding this during a inspection is cost effective.

Having your door falling off away from your base is not.

Inspection of these items is normal.

Someone that does not write them up is NOT your "friend".


BTW- You do NOT have to be an A & P to look @ these.


Lubrication per the SM is often ignored for these & the window

hinges & latches.

That minor item WILL extend the life but vibration

still takes a toll.
