Mr.Saunders needs to check his facts. The Marine Corps, Navy, and Airforce have all supported the Osprey from the start. The Army was an initial supporter but backed out in favor of more money for H60’s. I suppose he wants to get rid of the F22 now that it killed a test pilot!

Working on aircraft engines for 11 years in the military, we always used safety wiring for bolts and nuts. Why was these bolts not safety-wired?

The V-22 since the beginning has been haunted with crashes and death. The services tried to kill this program in the 80’s but it got shoved up their _ _ _ by Congress. They need to go away or sell them to a third world country.

Loose bolts can be attributed to a variety of causes –and they ARE ALWAYS a MAJOR concern for those inspecting/assembling and checking!
This problem HAS occurred before several times and places including NASA items! Incorrect machined screw threads a very serious art and science by the way, incorrectly measured/inspected threads, incorrectly marked/stamped identified type/grade of bolts, incorrectly assembled/stripped/damaged bolts, ..
Lockwire is also an art and science– a technique if you will — If it is not done properly it will NOT prevent bolts from loosening it may prevent them from becoming fully disengaged and free flying loose but that depends on how well it is done and quality of lockwire itself. Many tried and true military specifications for these items have been superceded,cancelled replaced by not so strict commercial specifications.

How about bolts and nuts that you can safety wire?

Did this grounding affect only USMC Ospreys or USAF too?

Sense Lock washers can’t be used in a lot of the areas on any aircraft. There are casalated nuts with cotter keys???. and self locking nuts that are great. So apparently some one failed to propertly torque the said nuts. Where was the Quialty control. or technical inspector at???.
