Bearings

An IA told me the other day that wheel bearings really don't need to be done every annual -- every 2 years is sufficient. Any thoughts on this? BA
 
[FONT=&quot]FAR 43 Appendix D[/FONT]
[FONT=&quot]e) Each person performing an annual or 100-hour inspection shall inspect (where applicable) the following components of the landing gear group:[/FONT]
[FONT=&quot] (7) Wheels—for cracks, defects, and condition of bearings[/FONT]
 
Ya get what you pay for!????

Want to see the last set of brake discs I pulled from a spam can?

How about your axle? Any cracks?

We have one of those IA out here. What is the point? *The loser came into my shop yesterday looking for advice. His pen must have been out of ink.

End of rant,

At this time I have an OLD Cessna "100 Series" Service Manual.

"At the first 100 hr. insp. & @ 500 hr intervals thereafter, remove the wheel bearings & etc etc."

The lube diagram also calls out a 500 hr. "Clean & repack".

Also in my possession is a Piper Lube Chart.

It requires removal of the Main Landing Gear attach bolts & regrease @ 100 hr intervals.

I've seen a lot of bolts covered with dope from the last recovery; 20 years earlier.

Evidently "Low Maintenance" evolved into "No Maintenance"!

The T-Craft guys are working up some type of Service Manual to reflect the years of experience .

Should we do likewise?
 
Can't argue with the FAR and the FAR overrides the shop manual. Bearings can not be inspected properly unless they are clean.

I guess rocket prefers mechanics who bluff their way through something they haven't encountered before rather than seek help.

Jeff,
just so you know I stared at my comment for a few seconds longer then usual and noted its inflammatory non productive nature. I really should have deleted it but it was after all a rant in which without the…rest of the story…one really could not understand my feelings on the matter and most importantly how the issue of our safety and the safety of those we in our delegated authorization are responsible for.


For example, last summer some one with one of those new little jets had an alternator out and asked me if I could replace it. I told him I did not have the recency of experience to sign of the replacement and also did not feel i had any business touching his shinny new oil burning toy even though in another life I had been checked out in the heavies up to the triple seven. That being said another mechanic with much less experience, and in my opinion not enough to wipe the wet from behind his ears, replaced the alternator for him.


I guess my point is that when another A&P comes into my shop to ask about something he has absolutely no business touching without a good year of OJT or at least a fancy piece of paper saying he is aproved, then he should have enough sense to recommend the repair to the qualified.


I must admit i am slowly turning into one of those crotchety anal retentive A&Ps you find at any(every) dirt strip wooden hanger. You know the one that makes you redo the safety wire over and over and over again until it looks perfect or wet sand that dollar patch one more time but at the same time he shares his tools and shop and time…and perhaps most importantly his love of aviation.


Just so you know I went over to help out the above mentioned mechanic…against my better judgment.

I for one would like to commend your decision to assist & COUNSEL the young A & P.

None of us are born with experience & the "Charles Taylor Candidates" should be the leaders

of the profession.

My comment on "Counsel' was included in that at times it may be appropriate to advise them

to change their course of action.

After many hats & years I've come to despise folks in any field that have knowledge &

refuse to share it.

Obviously; anyone participating in this forum does not fit that description.
