Reviews

Sorry thread size and rolled forks are noted in description. I could not see the description while writing the review. The rest still applies

There never was a 5 year inspection in AD93-10-06 for the wing strut forks. That AD has also been superseded. The current AD is 2015-08-04 which requires the strut forks to be magnaflux inspected every 500 hours and replaced at 2000 hours time in service. Replace at 1000 hours time in service if on floats. There are no calendar inspection requirements for the forks in either AD only the unsealed wing struts. Some of the sealed wing struts use a different fork with larger threads which does not have the inspection requirements of this fork. If these are the smaller thread that should be noted with the thread size. The description should specify that the forks have rolled threads which is part of the AD to be approved.
