uh-1v rotor blade

blacklion...

You are asking WAY too much from the forum membership.

You need the BELL UH-1V (?) engineering drawings, material specs and the processes-specs. These are likely proprietary to either BELL or the DOD. There is one company I have heard of that migght supply drawings [$$$]... but may not have access to the specs.

Also You MUST have the failed article [blade] for detailed analysis [inspection and lab work].

I believe that this project is NOT practical in a field or "unofficial environment", UNLESS You have a lot [YES, A BOAT-LOAD] of failure analysis experience under Your belt. There will be MANY operational, maintenance, environmental, engineering and material aspects to consider that could factor in... or "cross-factor". This is based on my +,-20yrs of this kind of work [as a USAF DOD engr].

IF the helo is a US or foreign military acft... then the US DOD engineering folks [USA, USN or USAF depot engrs] should be the ones to get this failure analysis accomplished under a "HAP" [High Accident Potential] imperative [assuming that the acft safely landed]... if not the “mishap board" should have this done ASAP as part of the investigation.

IF the helo is a civilian acft, then a strong word to the FAA is required.
