Pete:
I don't believe too many Part 91 (private) operators follow this bulletin, but perhaps it's a requirement for other operators. There is a company that specializes in aircraft seat belts and advertises in Trade-A-Plane. They are at
www.aircraftseatbelts.com and they may be able to reweb the belts and certify them in compliance with the SB. Drop them a line at
info@aircraftseatbelts.com
Regards,
Ernie
PS. I hear that Jean, who attended last year's SOAPA Meeting, is back in the UK. Give her my regards.
