Narrative:
At approximately XX00 I was in cruise in an small transport over the panoche VOR. I was in the process of relocating the aircraft from sacramento to santa barbara, ca. Somewhere in the vicinity of panoche VOR I fell asleep and awoke to find the aircraft in a diving right turn. I recovered the aircraft and returned to cruising altitude and proceeded to the santa barbara airport. Factors that contributed to this were the fatigue from a 3 day trip. I arrived at the hotel in sacramento at approximately ag:00 on 3/xx/90. I retired that night around midnight and then was awakened shortly after XD00 by a phone call from company operations. They wanted me to reposition an aircraft to santa barbara. I was scheduled to deadhead home on airlines that day. I feel that with the time change occurring and the short notification allowed me only 2-3 hours sleep. I feel the lack of normal rest and pressures from the company to relocate the aircraft were primary factors. The company should have realized the need for repositioning the aircraft prior to my arrival at the hotel the previous evening so that I could have planned proper rest. Even though the flight was conducted under far part 91, the company should have adhered to far part 135 crew rest requirements.

Title: ALT DEVIATION EXCURSION FROM CLRNC ALT, HEADING DEVIATION WHEN PLT FEEL ASLEEP DURING A FERRY FLT.
Narrative: AT APPROX XX00 I WAS IN CRUISE IN AN SMT OVER THE PANOCHE VOR. I WAS IN THE PROCESS OF RELOCATING THE ACFT FROM SACRAMENTO TO SANTA BARBARA, CA. SOMEWHERE IN THE VICINITY OF PANOCHE VOR I FELL ASLEEP AND AWOKE TO FIND THE ACFT IN A DIVING RIGHT TURN. I RECOVERED THE ACFT AND RETURNED TO CRUISING ALT AND PROCEEDED TO THE SANTA BARBARA ARPT. FACTORS THAT CONTRIBUTED TO THIS WERE THE FATIGUE FROM A 3 DAY TRIP. I ARRIVED AT THE HOTEL IN SACRAMENTO AT APPROX AG:00 ON 3/XX/90. I RETIRED THAT NIGHT AROUND MIDNIGHT AND THEN WAS AWAKENED SHORTLY AFTER XD00 BY A PHONE CALL FROM COMPANY OPS. THEY WANTED ME TO REPOSITION AN ACFT TO SANTA BARBARA. I WAS SCHEDULED TO DEADHEAD HOME ON AIRLINES THAT DAY. I FEEL THAT WITH THE TIME CHANGE OCCURRING AND THE SHORT NOTIFICATION ALLOWED ME ONLY 2-3 HRS SLEEP. I FEEL THE LACK OF NORMAL REST AND PRESSURES FROM THE COMPANY TO RELOCATE THE ACFT WERE PRIMARY FACTORS. THE COMPANY SHOULD HAVE REALIZED THE NEED FOR REPOSITIONING THE ACFT PRIOR TO MY ARR AT THE HOTEL THE PREVIOUS EVENING SO THAT I COULD HAVE PLANNED PROPER REST. EVEN THOUGH THE FLT WAS CONDUCTED UNDER FAR PART 91, THE COMPANY SHOULD HAVE ADHERED TO FAR PART 135 CREW REST REQUIREMENTS.
