Certified logs
I have run into the same muddle. 23 years of airline computerized flight pay logs amounting to more than 15k hours plus logbook showing more than 5k hours before that. In addition to years of PC forms.
Rich and worthless plus Park won't represent me unless I have certified books. Luckily, there are still a few companies that will throw you in the box and let you show them what you can do. That usually takes care of the logbook problem.
If I went to my local Aviation agency or previous airline they would look at me in amusement when I ask for them to certify logbooks. You can get fake passports, licenses, and documents.....just how hard is it to fake logs? Few quid and company stamp?
