Flight crew of a learjet, LR35, could not obtain a right main gear down and locked indication when approaching to land at an uncontrolled airport. The crew used the emergency gear down system which did not show a change in the gear down position. However, a successful landing was made with no gear failure. Crew referred to flight manual and home base maintenance and subsequently flew the aircraft to home base without incident.

Narrative:
Captain called for gear down, copilot said no right main indication. All resources to determine that gear was down, including blowing down gear were used. After successful landing, crew communicated with home base maintenance and referred to aircraft flight manual about returning aircraft to home base for maintenance. Home base is hio, hillsboro, or. Nothing could be found that indicated that the aircraft was unairworthy, aircraft was dead-headed to home base. After arriving at hio, logbook was filled out for trip, and problem was written up in maintenance log. After talking with maintenance, chief pilot was determined that a ferry permit should have been received for the dead-head flight to hio. It was determined that processes be put in place to review sits like this in a more timely manner to prevent a recurrence.

NOTHING COULD BE FOUND THAT INDICATED THAT THE ACFT WAS UNAIRWORTHY, ACFT WAS DEAD-HEADED TO HOME BASE. AFTER ARRIVING AT HIO, LOGBOOK WAS FILLED OUT FOR TRIP, AND PROB WAS WRITTEN UP IN MAINT LOG. AFTER TALKING WITH MAINT, CHIEF PLT WAS DETERMINED THAT A FERRY PERMIT SHOULD HAVE BEEN RECEIVED FOR THE DEAD-HEAD FLT TO HIO.
