Paper pilot certificates will expire March 31. You can either go online to convert paper pilot certificates to plastic or fill out a form and mail it to the FAA in Oklahoma City.Here is what the FAA regs say about the change:
FAR 61.19(h): Duration of pilot certificates. Except for a temporary certificate issued under §61.17 or a student pilot certificate issued under paragraph (b) of this section, the holder of a paper pilot certificate issued under this part may not exercise the privileges of that certificate after March 31, 2010.
