Aztec Flap Tube AD and related Service Bulletin
Can anyone point me to a link for Piper Service Bulletin 1051B? It is
what the Aztec falp tube AD refers to for compliance (2003-09-18?). I have not been able to find it on-line. I'm trying to help someone figure out the best way to comply, but if I can't read it I can't understand what is required. Unfortunately, they did not keep the copy that was mailed to them. TIA. z |

I've found it almost impossible to find Piper's SB's online.
When we bought our Aztec, the AD had been complied with by replacing the torque tube. I'll look through our logs in the next day or two to see if there is a copy of the SB. If I recall correctly, the AD calls for inspections every 500(?) hours to check for cracks in the ends of the tubes. I also believe it calls for replacing the wooden plugs in the ends of the tubes with plastic plugs. It requires removing the tube from the aircraft no matter if you inspect it or replace it, however, if you go the replacement route, you can save time/labor on the removal process with help from a sawzall. I've had quotes of around $2000 including labor to replace the tube. There is another local Aztec owner who is also an A&P / AI, I'm sure he'll have a copy of the SB, it's just tough getting in touch with him. Jim "zatatime" wrote in message ...

Thanks, but don't go through too much trouble. You pretty much answered the initial question I had below. If I recall correctly, the AD calls for inspections every 500(?) hours to check for cracks in the ends of the tubes. I also believe it calls for replacing the wooden plugs in the ends of the tubes with plastic plugs. You are correct. I found this in the AD. It requires removing the tube from the aircraft no matter if you inspect it or replace it, however, if you go the replacement route, you can save time/labor on the removal process with help from a sawzall. This is the info I was looking for. I didn't know if you could do the inspection with the tube in the airplane. Since you need to pull the tube for inspection it almost makes sense to just replace it. You'll save some on labor, and never have to do it again (in theory). I've had quotes of around $2000 including labor to replace the tube. Ouch! The AD says $480.00 for labor and $572 for parts. I know those numbers are bogus, but I didn't know they were at a 50% discount! There is another local Aztec owner who is also an A&P / AI, I'm sure he'll have a copy of the SB, it's just tough getting in touch with him. Jim Thank you very much for the reply. You got me started in the right direction. If you do find the SB great; if not I'll keep digging. Thanks again for the help. z |

Found the SB but ours is SB 1051A dated Oct 9 2001, not 1051B It is
instructions for replacement of the torque tube. Jim "zatatime" wrote in message ... Can anyone point me to a link for Piper Service Bulletin 1051B?

TIA. z In the process of going through this on my Aztec as well, they were going to pull the torque tube yesterday and do the inspection. Depending on what the replacement torque tube cost, I figured I'd just have them put in the replacement, which only needs to be checked every 2500 hours, not every 500 with the currently installed one. I'm also told that they replace the wood caps with plastic since the wood could absorb water and cause corrosion. I see the various costs quoted in earlier replies, I'll post what my mechanic tells me, they're almost done with the annual and I should have a squawk list to go over with them this coming Monday or Tuesday. SO far things are looking pretty fair, some leaks that need new seals, etc. They did see that the brakes were rubbing the inside of the tires pretty bad, so I'm not sure if the previous owner had the wrong tires on or if I'm missing a shim somewhere. Engine compressions were all in the 70s which was good to hear as well. I'll post a report on my annual if anyone is interested. This is the first one for the Aztec since I bought it. -- Louis L.

Tires should be 700 x 6 8 plys for the mains and 600 x 6 6 plys for the
nose.... guess how I know?.... The previous owner had the wrong tires on ours too! 6 ply mains instead of 8 plys and retreads are tough to find. Jim "Louis L.

I thought it was just some extra layers of rubber (presumably because they're holding more weight?) I know when I put my C152 back together that it used 6x6.00 6 ply, but hadn't thought much about it. So I guess the question is, what does the number of ply's measure on an aircraft tire? Why would having a lower ply count rub on the brakes while a higher number does not? What year Aztec do/did you own Jim? I thought Kyler Laird was the only other Aztec owner that regularly posts on the group. -- Louis L. Perley III N46000 - C152 N370 - PA-23-250 |

thought it was just some extra layers of rubber (presumably because they're holding more weight?) Exactly. Why would having a lower ply count rub on the brakes while a higher number does not? Ours didn't rub, they were just too light of tires for the job. The POH calls for 8 plys. What year Aztec do/did you own Jim?

"Louis L. Perley III" wrote: Don't know much about tires, but what does the number of ply's reference? A tire is built up of layers of some sort of fabric (called the cord). A heavy layer of rubber is then applied over the cord and tread is molded into the rubber. The number of plys is the number of layers of this fabric. If the layers of fabric are applied diagonally across the tire, it's called a "bias-ply" tire. If they are applied perpendicular to the tread, it's called a "radial" tire. Automobile tires are usually also "belted", which means that additional layers of some sort of material are laid between the plys in the same direction as the tread.
