Narrative:
The above aircraft received an inspection in december at which time it was signed off as airworthy. The inspection program used to perform the inspection was a beech 150 hour/18 month primary inspection. The revision date of the service manual was jun/xa/95 which at the time of the inspection program/maintenance manual was believed to be current. The current revision of this manual is feb/96. This revision changes the inspection program to 200 hour/24 month inspection intervals. With this revision, the old inspection program became obsolete. Therefore, the aircraft was not inspected to the current revision and could be deemed as unairworthy. All airworthiness directive notes were complied with at the inspection, the aircraft is operated under part 91 and is flown less than 100 hours per yr. The error was discovered by FAA personnel performing a routine station inspection. The usage of an outdated manual was done in error by misreading the revision date. A current revision of this manual will replace the obsolete one.
