Default Annual Report Final. "Long"

Day 1, All major airframe, cable and Engine inspections complete.
Reported On That In Post #1

Day 2, Fixed Discrepancies on Day 1 We Did an In-depth Control System's
Inspection, After Resetting Trim Indicator that was way off. Very In-Depth
Fuel System Inspection, and reinstalled all inspection plates and wheel
pants.

We found that the gascolator was corroded and was leaking from the shaft. We
removed gascolator upon inspection we found an O-Ring to be brittle and
cracked with pieces missing. Upon removal of the O-Ring it came out in
pieces and they would crumble in you hand.

I chouse to repair the gascolator myself I took it home and after 2 hours of
scrubbing with no progress on the corrosion on the gascolator's exterior I
decided it needed a acid bath. After 20 min of soaking I pulled it from its
bath neutralized the acid. I began the cleaning process and getting it ready
for dye check for cracks. I did my dye check no crack found. I dipped it in
an acid bath for another 5 min for a before final cleaning.

On to the parts for measurements. Pull out my handy dandy dial caliber and
measure the plunger shaft where the O-Ring is at the shaft is not worn many
half a thousandth of an inch at the O-Ring where point. The next part is the
main body of the gascolator the hole the shaft goes in to I do an inspection
looks good. The 2 washers and spring for the plunger shaft no unusual where
is found! Parts Look Good

Went to the Local FBO they have all 3 O-Rings and the gasket that goes
between the screen and the main body cost about $20.00 purchased a bunch of
extra O-Rings

I Used Some DC4 for O-Ring Lube Installed the shaft O-Ring in gascolator
body with the proper O-Ring install tool was a nice snug fit. I installed a
new fuel screen gasket installed fuel screen. I lubed the Plunger shaft with
DC4 and slowly installed the plunger carefully so I would not damage the new
O-Ring. I Install the threaded tube for the gascolator that also holds the
fuel screen down test action works great. I Lube and install new fuel bowl
O-Ring install fuel bowl. I installed fuel bowl drain hole O-Ring Install
retainer washer and nut now time for a leek test.

To test I used a regulated compressed air @ 12psi don't think that gravity
fuel pressure is over that. I capped the Primer line and output line
installed an air fitting on the inlet side applied air no leaks.

Day 3, We return for the hangar today 10-26-04 we over look all the paper
work that need's to be done says gascolator look's like a new one talked
about what I did to it said was a bit over done he inspected my work every
thing was great and off to the install we go. Install and operation test go
as planned. Time to put the cowl on you know it is really nice and easy with
new cowl mounts things just work great.

We pull it out of the hanger for the Run Up, Everything seems to function
properly smooth. To my surprise the throttle response was a lot better must
have been that set of 8 new plugs.

We park the airplane after that 20 min Run Up look for leaks none found.

We go in the hanger and finalize all log book entries annual complete we
exchange money for logs, shake hands and discuss our long term business
relationship.

I now have a better understanding of 7676U Problem points and places that
need that little extra attention. I think that they could have used a dust
boot on the gascolator to protect the plunger shaft O-ring from dust and
dirt just my 2 cents on that note.

Total A&P IA bill was $320.00

Total For Parts "Unknown" have not added it up but under $300.00

Knowledge recived from this annual priceless I would have been more than
happy to pay triple that amount.
