It sounds like the FAA requirements are stricker and they could essentially have a line check every four months now at CAL
There have been a few questions asked about the line checks that are being given to the over age 60 pilots. When the FAA Age 60 rule was replaced by the Fair Treatment of Experienced Pilots Act, an over 60 pilot was required to be given a line check every six months. However, it varies somewhat from the time guidelines that happen prior to age 60. A pilot who is under age 60 is based on calendar months and has what has been known as early month, due month, or grace month. This does not apply to the over 60 pilot. For example, pilot X has a line check on Feb. 3 and it is passed. After Aug. 3 (exactly six months later), that pilot becomes illegal to fly a trip. The new rule does not allow that pilot to fly until Aug. 31 as it did prior to them turning 60. Also, because the timeline is much more stringent, Flight Operations will always try to get the line check accomplished as early as possible to prevent that pilot losing qualification. This usually means that four months after the previous line check, you are on the master list for a line check again.
