I've been flying a beat up twin piper lately and one if it's most recent issues is that the left engine vibrates more than normal on start up. It shakes enough to be felt in the controls and anywhere within the plane. Our mech found a cracked lower motor mount and signed it off to fly. Seems iffy to me.....what's your opinion?
Cracked motor mount?
- Thread starter FODell
- Start date
What maintenance did he perform on the mount?
None that I know of...

Yeah pretty much. Its up for annual this month. Should be interesting to see what all is found.
Did you ask him?
Also, do you know what criteria he used to determine airworthiness? Are there any guidelines for allowance of operation with a cracked motor mount?

If there really is a cracked motor mount, and he really did release it for flight without fixing it, that is a definite, 100%, absolute, no-go, ground the airplane right now problem.
I have asked. Via text. (his favorite method of communication) No reply. I'm fed up with him. I'll be having a talk with him tomorrow to get to the bottom of this one.
Thanks for the info. My owner and I have had it with this mechanic. This may have been the last straw.
Also, what part of the mount needs to be cracked to warrant a grounding? the rubber only? I have heard back from him now and says "dude they're made of rubber, they crack"....
Correction. It is a LORD mount that is cracked.

Ohhhh that's a LOT different.
The rubber part cracked? Eh, not such a big deal. If you're noticing a vibration and I was the one who owned the plane, I might say change it sooner rather than later. I initially thought you meant the tubular steel engine mount-that's a big deal. Rubber puck? Not so much.

Used to believe that. Not so much any more.

If it's just the LORD mount that's cracked AND the aircraft is due for annual by the end of this month, the mechanic is not doing anything shady. A cracked rubber mount does not make a plane airworthy and it's a perfect time to fix it at the annual.
I hereby motion that all mechanics should have to take enough flight instruction to sucessfully solo an aircraft! Simultaneously all pilots should take some rudimentary classes in aircraft maintenance and terminology!
All in favor say Aye!
(Prediction- the above mentioned motion will fail horribly)

Aye, with the caveat that being a pilot helps a mechanic MUCH more than being a mechanic helps a pilot.If it's just the LORD mount that's cracked AND the aircraft is due for annual by the end of this month, the mechanic is not doing anything shady.

I really believe that doing an owner-assisted annual (even if you're not an owner) should be a pre-requisite for getting a commercial license.

Actually I guess that depends on how cracked... you have an increase in vibration too... I think it's time to change it.
