sekomel Posted April 7 Report Posted April 7 Hi everyone, After completing our recent landing gear maintenance, we noticed a slight misalignment between the main landing gears. Specifically, the left main landing gear appears to be slightly more inward-angled compared to the right side. It’s not a huge difference, but it’s noticeable. We’ve gone through the Mooney maintenance manuals in detail, but we couldn’t find any clear reference regarding alignment tolerances or adjustment procedures for this. Has anyone experienced something similar or have any insight into what might be causing this? Any recommendations on what we should check or measure would be greatly appreciated. By the way, no incident, damage, or anything else.. Best regards,
Flyler Posted April 7 Report Posted April 7 What parts were replaced? Edit: I should have mentioned, once you realize Mooney main landing gear look like this, you will go a little bit crazy. The angle of the ground, wing dihedral, and angle between your eyes and the gear will make them seem different every time. I'm sure if you measured the angle accurately, you would find some variance between all the gear too. 2

Former MS member and very helpful Canadian MSC owner Clarence/M20Doc previously commented: "Mooney landing gear have fixed length side braces, many sit at weird angles, less that 90 degrees to the surface. Pipers have adjustable side braces." 1
EricJ Posted April 8 Report Posted April 8 Yes, it's normal. There is no alignment spec or procedure for Mooney landing gear. 2
