Good Luck...Had a neighbor whose AW certificate blew out of the cockpit of his Pietenpol. Even though he had an FAA signature in his logbook proving it was inspected, the signer had retired and they gave him paperwork from scratch wanting another 40 hours flown off locally,(it had over 300 hours on it).
Thankfully I got to fly off most of those hours for him. Hopefully since yours was issued by a DAR it will be easier.
