The "Mystery Vibration" saga in the 74 Cherokee 140 (O-320 - E3D)continues. I began the quest by addressing those items that were due anyway. Swapped out the plugs with the old set and saw no difference. Had the mags overhauled as they were 20 hours away from their 500 hour mark where I usually...

Well, I finally have one. The weird vibration out of nowhere. About 6-7 flights ago, i noticed a very slight rhythmic vibration during a smooth straight and level flight. About 4-5 seconds of smooth flight and then 2-3 seconds of vibration. I chalked it up to the air conditions. Over the years, I...

Thought I would spruce up the old bird with a new set of rudder pedal pads. I have seen several planes where they have either tie-wrapped them on or, worse yet, SCREWED them on. Looking in the ol' Piper parts inventory I see that they are WHAT!!!!! $84.39 EACH!!! Ah, yes. The old "Aviation...

Changed out the bow ties for rams horns (at last). Now I have 2 bow ties in good condition with pins, spacers and late model medallions (3 color). All you need is 2 new cotter pins. Seems like $200 for both is fair. Takes about 15 minutes to swap them out. If nobody from the group wants them, off...

Finally found an 810+/r to replace the Com 120. Since I bought Jay's unit as a spare when he did the same thing, I now have 2 120s. Anyone interested in buying one of these? Considering offers over $200 + shipping for one of the units. If nobody from the group wants it, it goes on...

When I had my tanks out in 1999 for the paint job and hose replacement, I also noticed stains from the sending units downward. I decided to replace the gaskets and reseal the things "while I was at it". The local wrenches said that getting the screws around the sending unit to seal completely was...

Well, did my first seal swap on the 140 on all 3 legs. Took me and the wrench about 5 hours total. Completely slimy, dirty job. Remember, I worked in my father's body shop as a younger man, so I am no stranger to being filthy. This was worse. Being dirty WITH oil/grease involved is way worse than...

Tired of the ugly bow tie yokes (and the repetitive inspections). Anyone have 2 ram's horn 1.125" yokes for sale? Piper P/N 79276-00V. Thanks, Mike

Still trying to find out if anyone has removed the old bowtie yokes from their shafts and replaced them with ram's horns. Lots of folks changed out the yoke/shafts as units, but nobody will fess up that they actually swapped out the yokes themselves. Since Piper lists the yoke/shaft as one part...

My PAI 700 has performed quite well for the past 4 years or so until now. I bought the "official" mounting bracket after seeing others that were mounted without the bracket failing badly. Lately, even after recalibration, I have noticed it seemed to be off 5 degrees or so between 350 and 10...

Anyone know if a Narco DGO 10 can be hooked up to a MK12D with GS? Also, what is the "converter" for that some units have? Thanks, Mike

Retrofitting diesels on existing airplanes doesn't make much sense in the US, where the fuel cost differences between 100LL and Jet-A are relatively small. However, using diesels on new airplanes makes a lot of sense. If you look at the price of a Diamond plane in Europe, the diesel version...

If I own a single engine airplane that needs some interior upholstery and trim repairs, can I contract with an automotive upholstery repair shop to do the work, or do I need to use an FAA Repair Station? Thanks, -- Mike Schumann

Did an oil change on my Tripacer. I've done them before and they're pretty easy. This one though, it looks like my oil screen cover is leaking like crazy. I actually changed the oil last month right before it went into annual. They flew it (looks like a couple of hours worth) with no leaks...

My upper rotating beacon has stopped rotating and I am debating whether to overhaul it or replace it with one of the new Whelen flashing beacons. The flashing beacons are all solid state with no moving parts but cost $800 and I am also concerned about noise since the beacon is located a few...

I would like to buy a fuel truck! 5,000 to 10,000 gallon preferred. I have been watching ebay and rbauction.com and I was wondering if anyone knew of other sources? How can I find out if the government is selling one? Thanks! Mike MU-2

I have recently converted from NiCad to lead acid batteries which are supped to have a life of 2-3 yrs. The batteries cost about $1500 for the pair and I am interested in maximizing their life the extent practical. I have heard about "pulse chargers" that reportedly reduce sulfate on the battery...
