3 Point Primer Kit for Installation with Air Plains 180HP engine upgrade, STC SA4428SW.
If you have an existing Air Plains 172-180hp installation you very likely have the primer system that is original to the aircraft. The standard installation reuses the existing primer lines and reinstalls on the new engine. Air Plains has collaborated with Lycoming to provide a custom primer line kit for Air Plains new and existing customers.
If you have an Air Plains 172-180hp that was done prior to 2021 it is very likely the original primer system was reinstalled with the new engine. While the previous process works just fine, Air Plains has added an option to the upgrade kit now offering a new three point primer kit.
Approved Replacement Part Number:
172B, 172C, 172D, 172E, 172F, 172G, 172H. 172I, 172K, 172L, 172M, 172N and 172P model with STC SA4428SW.
