When does the instrument written endorsement expire?

Asked by: 6631 views ,
Instrument Rating

I took an instrument ground school course 3 years ago, took practice tests and received a sign off to take the test. I did not test. I also completed self study king, Gleim, and asa programs. Is my 3 yr. old signoff still valid to take the instrument written? I cannot find any restrictions about this in the far's

    I believe that your 3 year old sign off is valid. There is no indication in the document for Conduct of Knowledge Tests that there is a time limitation for an initial test and once upon a time, far, far away I was a proctor for Knowledge Tests and I recall this being discussed, or noted, or somehow covered and I believe the answer was “no expiration.”

    However – before I got myself all ready to go I’d give the actual center you’re going to use to take the test a call and get their interpretation. If they say it’s 2 years, 1 year or 20 minutes, then you can choose to either show them they are incorrect (if indeed they are) or just find yourself an instructor willing to sign you off. I wouldn’t just turn up and hope the testing center sees things the same way without some research.
