RV-12/12iS Service Bulletins/Letters released 1/23/2023
The following service documents for the RV-12/12iS were released today.
NOTE: If you need to order SB or SL parts for multiple RV-12/12iS aircraft (unusual), it is important that you place one web store order per serial number. We will not ship multiples of these kits/parts for a single serial number. If you place multiple orders to cover multiple aircraft, specify the serial number for each order and we will work to combine the orders if they are shipping to the same person (assuming they are ordered in close proximity to each other of course). The SL and SB kits and part numbers described in each document are available to search and find on our web store. If one of the kits/parts shows "back ordered," it's just because the kit bundles are not yet updated in our system. You can go ahead and order today. Also, various sections in the RV-12/12iS kit assembly instructions (plans) were updated to coincide with these service doc releases and in some cases are called out in the SB docs to be referred to while complying with the service info. Those are uploaded and available on our website in the Service Information and Revisions section.
SB-00059 - RV-12iS Canopy Latch Block Improvement
Multiple reports from the field have shown that the canopy latch handle can be forced past the canopy latch block. Once past the block, it becomes impossible or very difficult to open the canopy without disassembling the handle from the outside or using destructive methods to force the latch back over the latch block. For this reason, a new canopy latch block has been designed to add a feature that prevents the canopy latch from being moved past the edge of the block. This is a fairly simple replacement of the canopy latch block with the new version, which can be completed in the aircraft cockpit. This part is now shipping in kits.
SB-00064 - RV-12/12iS Exhaust Flast Spring Installation
Addition of flat spring parts to the #1 exhaust tubes to address potential for slip joint separation and/or contact with engine cowl. This is a fairly simple operation that requires the removal of the engine cowl and camping on of the springs to the #1 exhaust tube. Thes parts are now shipping in powerplant kits.
SB-00067 - Reinforcement of the WD-1223 Counterbalance Arm
Data from the field suggests that the WD-1223 Counterbalance arm is subject to fatigue failure, which could result in the mass balance weights separating from the stabilator. Complying with this service bulletin will prevent the fatigue failures. There are a couple of methods of accessing the counterbalance arm, and the amount of time needed will vary by the method chosen. Note that if you remove the stabilator you may want to also install the optional SL-00068 spacer kits, described below. These parts are now shipping in kits (see the bulletin for details).
SL-00068 - Optional Stabilator Hinge Spacer Installation
Permanent optional shims are available to replace washer spacers and reduce the difficulty of installing/removing the RV-12/12iS stabilator. Installation of this shim kit will simplify and make less frustrating future removal and reinstallation of the stabilator. A one-time project, long-term simplification. Optional, and now included in shipping kits.
SL-00070 - Optional Fuel Tank Inspection Fitting
Describes the optional addition of a fitting to the top of the original model RV-12 tank to allow for easier inspection of the fuel strainer.
