Trigana had issued the Engineering Instruction (EI) identified by number B737-EI/32/083R1 with the title DVI Main Landing Gear Shimmy Damper Bolt. However, the EI did not reflect the content of Service Letter (SL) 737-SL-32-057-E issued by the Boeing such as the inspection of the apex bolt, regularly bleed the hydraulic manifold of the shimmy damper and define the maintenance interval. The absence of inspection requirement to the shimmy damper assembly might lead to the similar accident.Therefore, KNKT recommend to implement the Boeing SL 737-SL-32-057-E (or the latest revision) requirement.
