Service Bulletin #5 Correct Wheel Alignment
This SB #5 is advisory in nature.
When assembling landing gear, particularly wheel assembly, take care to ensure that alignment of the wheels is correct. The lineup of the wheel should be straight to ground travel path; toe-in and toe-out must be avoided. Toe-in will cause landing gear chatter.
Alignment is ensured by correct rotation of the landing gear shaft before pinning in place at the upper bulkhead fitting.
The following picture shows correct alignment. The green line denotes the vector of the ground roll relative to the tire.
The following picture shows incorrect alignment, which causes minor to severe gear chatter on takeoff and landing. The orange line is as incorrectly assembled; the green line is what it must be reset to.
