SB M20-264 + aileron control tube guide blocks

[Martin S.]

Evening gents,

i am planning to replace the aileron control links on my M20J for definite compliance with M20-264.

I've got two questions in this regard:

1.) The SB/AD differentiates between parts for pre-M20L, and for post-M20K aircraft (see attachment 1). Lasar sells a kit, claiming the parts validity for all Mooney models (see attachement 2). What am I overlooking here?

2.) Is there a difference between the Lasar kit and ordering the control link parts mentioned in the SB directly at the factory?

Also regarding the aileron control tubes:

During the AD compliance operation, I plan on replacing the aileron control tube guide blocks that are at the wing root (will add a foto when available). I could not identify the part numbers for these blocks from the IPC. Does anybody know the part numbers and/or the corresponding IPC drawing?

I used (with DER sign off) nylon blocks for the control tube guides.  The hole is slightly smaller, but still large enough to function.  Thus, protecting the tube better against the steel structures.  It is not as abrasive as the factory blocks.

Thanks John - thats a good tip. I checked the guides. Interestingly, one of them was lose. Maybe something that got overlooked by previous anuals. The blocks are fixed with two screws to a metal rail that can be accessed from within the cockpit. I reattached it. No more play and no more chafing to any metal parts.

I am not sure that I replaced the guides to the ailerons, but I did replace the ones in the belly.  The material that the factory used (I am blanking on its mane just now) is abrasive and the material itself can wear the rods.

Not quite where you would expect to find the part number, but here it is. #18&19
