Good day to all! I am one of the personnel maintaining UH-1H and we have 30 UH1s in our fleet. Does anybody have ideas or references why the Main rotor (metal) blades we procure and use has differences in weight and length? We are encountering problems on the matching of Main rotor blades as this will cause aircraft vibration. Some blades have different locations on where the trim tab is located. We will greatly appreciate your response. email@example.com
I have recently found a bunch of New Old Stock T53 Vane blades marked Huey Engine 1967. The part number is 1-140-211-16 - some with 16N. I have looked through a ton of T53 manuals but cannot find this part. If anyone has any information or a diagram showing this piece I would be very grateful and would be happy to send you a vane blade in return for your help. Attached is a photo of one.
Thank You RT
