4. MQ9 load testing technical information.pdf

This is a technical maintenance manual chapter for the TPE331-10 Engine Lift Fixture (J-Hook), a specialized equipment component used for MQ-9 aircraft engine removal, installation, and storage container placement.

The TPE331-10 is an L-shaped lifting fixture featuring an anti-rotation mechanism with multiple attachment points along the spine and two stabilizing lanyard rings. Support equipment consists of a single torque wrench rated 40-200 in-lbs (local purchase). No specific consumables are required for maintenance. Pre-use inspection requires verification of overall serviceability, proper identification label attachment, and hardware security, with a critical warning that the maximum load limit is 750 pounds. The annual inspection procedure involves disassembly of the anti-rotation fixture, application of 1,384±138 pounds of test load to lifting clevis, a 30-second hold period, damage inspection, and nondestructive inspection (NDI) of welds per TO 33B-1-2 specifications. Assembly procedures specify precise torque specifications: anti-rotation fixture bolts to 50±2 in-lbs and hoisting ring to 60±2 in-lbs. Disassembly involves sequential removal of the hoisting ring, lifting clevis components (one bolt, washer, nut), and anti-rotation fixture components (two bolts, four washers, two nuts).
