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.

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.
