The question was, I thought, what the regulation says and how that affects your application for a pilot certificate/rating including the required logbook review by the examiner giving you the practical test. In the interest of ensuring that the person asking that question does not get turned back from the practical test for not meeting the prerequisites for that test, I provided an answer which guarantees the applicant will not have a problem on this issue.
If the applicant shows up with some of the required XC hours being on a flight where the landing farthest from the original point of departure was at an airport only 49.7nm away, the examiner is required by regulation and order to refuse the application and send the applicant home to complete the experience requirements of the governing regulations. If the FAA finds out after the fact that an examiner cheated on this and granted a certificate/rating to someone who did not actually meed the experience requirements for that certificate/rating at the time of the issuance, the examiner can be in serious trouble.
You may feel the spirit of the regulation should be observed rather than the letter of the law, but the FAA doesn't normally work that way, and in this instance, the letter of the law is a clear, objective standard which examiners do not have the discretion to waive. Further, if we're talking about the "spirit of the regulation", then where would you draw the line? 49.7? 49.5, which rounds up to 50 with two significant digits? 46, which rounds up on one significant digit? 40? 30? Just where does it stop, and what happens when one examiner allows "spirit" but another examiner requires "letter", or the examiners allows less for one applicant but not another on some subjective basis of the "quality" of the sub-50nm flight?
