Not only does the EU have restrictions on commercial flight with PIC over the age of 60. In some countries there is not part 121, 91 etc. It only has private or commercial flying. Some of these countries limit the age of the PIC in commercial operations to 60 (or 63). So you need to ask if your flight is commercial in nature, then apply the rule.
Also some countries don't publish an age 60 requirement. They refer to ICAO and adopt there advise as rule.
Always pays to check the AIP for that country if in doubt.
All of this seems stupid. How does a birthday limit the ability of that Pilot? One day at 59 years performing well and the next day at age 60 he is not fit to fly in commercial operations??
