A few problems have crept up in last couple of months that have halted the check ride before it begins. Most of these issues can be corrected with a little attention from the recommending CFI. Here's what showed up in the last month:
One applicant showed up without the required night time
One applicant showed up without the required solo cross country time
One applicant showed up without a current solo endorsement
And another showed up missing all the required check ride endorsement
Please take the time to review the regs and double check that your applicant is meeting the requirements for the certificate and/or rating sought. Some people hi-lite or tab the each requirement in their log book. Other Instructors have a checklist that list the completion date of each requirement.
Sometimes there are questions about a particular requirement in CFR 61. If you have a question call your DPE or the FSDO to get a good answer.
Endorsements: NAFI has an endorsement book that is more current than the AC. I've got a few copies I'll give you if you need. There are stickers that you can get online that will help as well.
Examiners are NOT allowed to start a check ride until the applicant meets all the requirements in CFR 61 (or 141) and is properly endorsed. Its tough when we spend all that time preparing for the big day just to be sent home empty handed.
