Synopsis: The SPRING-00002-L/R-1 can possibly cause wear to the throttle shaft, as the spring rests against the throttle shaft. This potential wear is located at the base of the throttle shaft. To prevent this, a retaining plate has been designed for the spring to be captured in, and serve as a bearing surface for, the inboard leg of the spring. Wear caused by the spring to the throttle shaft does not require replacement or modification of the throttle shaft, as long as the wear has not reduced the diameter of the shaft below the existing minimum diameter of the shaft (the minimum diameter of the shaft is located at the base of the shaft, where the shaft enters the carburetor housing).

This is the only reported instance; no other fatigue-related nose gear failures have been reported. The failure occurred in the nose gear leg at the point where the leg tube meets the lower attachment bracket, and was caused by a fatigue crack that propagated across the tube. The crack occurred at a location that is not visually inspectable. It is, therefore, strongly recommended that owners of RV-12/RV-12iS aircraft with the original style nose gear leg (WD-1201) replace that part with the available updated, reinforced leg - part number WD-1201-1. NOTE: Only original WD-1201 legs, which were shipped prior to June 10t, 2019, are affected by this service bulletin. If you have received a WD-1201-1 gear leg since that time either with your kit or as a backorder item, it is not affected. NOTE: In addition, only if your RV-12 or RV-12iS is currently under construction, and you received your finishing kit prior to June 10, 2019, and you have not yet completed the following steps in your plans, please contact Van's Aircraft to order a replacement gear leg rather than ordering the retrofit kits listed below. RV-12iS: Section 46iS-05, Steps 1-7 : Original RV-12: Section 46-08, Steps 1-3 If you have already completed those steps, please follow the instructions that appear starting on the next page.
