Cover W & B Bell 412 Ep 36652

This document provides the results of an aircraft weighing for a Bell 412 EP (serial number 36574) registered as HU-418. The weighing was performed in Bandung, Indonesia to inspect the aircraft with 5,000 flight hours. The empty weight of the aircraft was measured to be 7,485 lbs with a longitudinal center of gravity of 140.160 inches and a lateral center of gravity of 0.302 inches. Additional details are provided on the scales used, measurement locations, and calculations to determine the basic airplane weight and center of gravity position.
